FAQs: Mongoose Pro GM II Diagnostic & Programming

Here are a lot of questions and answers of Mangoose Pro GM II (the dealer or the copy), including software compatible (Tech2Win and GDS2), comparison with GM MDI & Tech 2 & Snap On Solus, diagnostic & programming & reprogramming issues….

I prefer Mangoose Pro II because of price...what do you think..will it work with my corsa d without problem? Or GM MDI better?

GM Mangoose PRO only for Opel/Vauxhall/GM with Tech2Win and GDS2.
Full coverage diagnostic and SPS programming
GM MDI can be use as a passthru for other software too
This is one of the difference
Both are good

I really just want to know what software and equipment I need to get me going with the GM Cars I actually have for diagnostics and programming.

GM Tech2 scanner or Tech2 software can used with gds2 or mvci, genuine is little high, but cheaper you can get from chine,
other is Mongoose Pro GM II, depend what exactly you want to do.

Is this Mangoose Pro GM 2 that is listed on Drew’s website?

Yes, this is the same as the Mongoose Pro GM2.

Can you buy the china clone of Mangoose GM2? If so, how much are they?

I bought mine for 70usd off obdii365.com

Will this interface perform diag. and programming on GM Global A vehicle (with SPS and GDS2)

Yes, the Mongoose Pro GM II will work with SPS, GDS2 and Tech2Win.

Is the MongoosePro GM II compatible with “Data Bus Diagnostic” Tool software?

Drew Tech has stated that as of early March 2015, the Mongoose Pro GM and the CarDAQ-M are both compatible with GM’s “Data Bus Diagnostic” Tool software.

When using Mangoose Pro GM II to SPS programming, does it program at the same speed as the GM MDI?

The MongoosePro appears to flash as quickly as the MDI.
The MongoosePro GM is definitely quicker than the Tech 2.

The MDI cost 4x more than the MongoosePro GM II but it is not 4x faster.

I have TIS2WEB, Tech2WIN, GDS2 & MDI. Is the MongoosePro GM II plug and play or does it needs to be configured?

The MangoosePro GM II is plug and play. Make sure to install the Tech2Win driver if you want to use the application.

Can this product be used as a replacement for mdi? Used for Tech2win and gds2?

MongoosePro GM II is compatible with Tech2win and GDS2 software for scan tool diagnostics, and it will flash GM-vehicles.

The MDI is a separate tool that is also compatible with Tech2win and GDS2.

Yes, the MongoosePro GM II is a replacement for the MDI.

Both tools do flashing.

Also, both tools require a subscription

Can you guide me the way to install Mangoose GM software?

First thing you need to do with this setup is access the Tech2Win driver settings.

Next trick I think is how to get security access.

Can the MDI do more than Mongoose Pro GM II can?

I already have a Tech 2 and a GM subscription and I need to be able to do the newer GM’s. Is there any reason not to buy this instead of the MDI? Will I be missing anything?

The Mongoose Pro GM II ALMOST does everything the MDI does. Currently that is:
– Module reflashing with SPS
– Diagnostics with Tech2Win software
– Diagnostics with GDS2 software.

UPDATE: The GDS2 software package includes the data bus diagnostic tool. Using the data bus diagnostic tool, the MDI will allow you to see voltage levels on the data bus, the Mongoose will not. The Mongoose will run the data bus diagnostic tool, but only partially.
Bosch corporate provides no support for installation and use of the MDI with GM software.
Drew does.
This is the big price difference.

Which tool do you recommend performing “advanced functions” on GM Vehicles? The cars I have are a 2003 Monte Carlo SS, and a 2009 Cadillac STS.

In order to perform “advanced functions” on GM Vehicles you are going to need something that talks with all the computers on the GM Vehicle.

The ones that I know of that do this are:

1) GM Tech 2 (will handle everything including programming the computers “updating calibrations”) This tool is being phased out but it’s still supported until they can get the MDI fully operational. Either way this works Stand Alone without a Laptop/PC.

2) GM MDI (Some say there are limitations with some model years but others say it’s better since the updates) Of course using Tech2Win to mimic what the GM Tech 2 does) – This performs like a J2534 Programmer as a Pass Thru Device. DrewTech and companies like Ease Diagnostics make J2534 Pass Thru Devices that will do this as well. And they sell their own flavor of Diagnostics Scan Software. Keep in mind only the GM stuff will do EVERYTHING for GM Vehicles.

3) Snap On Solus (This will do a lot not only on GM Vehicles but others as well. And it can do some of the advanced functions like Automated Brake Bleed on the ABS unit just like the GM Tech 2 and GM MDI) – Keep in mind there are many functions that the Snap On won’t do. The Tech 2 and MDI will allows you the option to access and control everything on GM Vehicles.

4) Mongoose Pro GM II (It can do things as GM MDI does.) Even the cheap Mangoose China clone is able to recover and reprogram modules perfectly and works with the newer h***ed 2017 GDS2!!!

In summary, Magoose Pro GM II features:

Plug and play: yes!

GM diagnostics and programming: confirmed!

Module recover and reprogramming: confirmed!

SPS programming speed: fast!

“Data Bus Diagnostic” Tool software: compatible!

Tech2win, GDS2, SPS: compatible!

Mongoose Pro GM II ALMOST does everything the MDI does!

CANdi adapter for Tech 2: What’s it? Why? How to use/communicate?

CANdi adapter user manual for  GM Tech 2 clone scanner:

What’s the candi module?

What is the real purpose of the candi module?

What is the CANdi module used for?

What’s the physical interface and LED?

“NO CANDI Communication Established”?

What’s the candi module?

An industry change in protocol from OBD II to Controller Area Network (CAN) is ongoing. In order to perform diagnostics on a vehicle that uses the CAN interface, you will need the Tech 2 and a CAN diagnostic interface module. The CANdi module connects between the Tech 2’s diagnostic link cable and the OBD adapter.

The Controller Area Network Diagnostic Interface (CANdi) is an in-cable module that works with the existing Tech 2 components including the VCI, cables and adapters. Installed, the CANdi module is fully backward compatible with current tester functionality. The module powers up in a way that makes it transparent to the user.

That is, unless the Tech 2 enables features specific to the CANdi module. This allows the existing Tech 2 software to be used with no changes, whether or not the CANdi module is installed.

What is the real purpose of the candi module?

The CANDI module reads the CAN Network on cars that have it. Corvettes 2005 and newer use the CAN Network. Still use a OBDII connector but the Candi module is needed to read the data on the CAN Network.

What is the CANdi module used for?

The primary function of the CANdi module is to add CAN capability to the Tech 2 scan tool.

The CANdi module:

– support simultaneous communications on three CAN buses

– provides high speed UART communications with Tech 2

What’s the physical interface and LED?

CANdi adapter connects the Tech II by way of the existing Data Link Connector (DLC) Burndy Connector. The vehicle side connection remains unchanged using the existing adapter to interface between the Burndy connector and the SAE J1962 connector. When functioning properly, CANdi’s LED flashes. In the vent of a problem，the LED will be constantly illuminated.

How will you do with “NO CANDI Communication Established”?

How-to’s of CANDI module communication errors:

“CANdi module was not detected for Tech2”

Or

“NO CANDI Communication Established”

First, please make sure you plugged the candi adapter in to the car and the tech 2 before powering up

Then, disconnect the connector leaving the candi adapter going to the OBD port. Plug it back in and make sure its real snug, then plug it into the obd port. I need to do this every now and then with my clone one. Usually it works after. Suspect the pins arent making the best contact.

Tech support from professionals:

1. With the car ignition off, connect the GM Tech2 and CANdi module (which is now one long cable).
   Power up the Tech
2.  You’ll get 12V from the DLC (now it takes me a half hour to find the “DLC means” Data Link Connector “and is what we also call the OBD2 connector, so be prepared to be stumped by TLA’s (Three Letter Acronyms)
3. At the main menu press F3-tool options
4. At the tool options screen select F9, CANdi Diagnostics
5. There are two tests on the next screen, run them both. The CANDI should talk to your 2004+ car
6. Either turn the ignition key of the car, or start it (for a C6 there is not an “on”).
7.  Press the EXIT button until the Tech 2 goes back to the main menu.
8. Select F0, Diagnostics.
9. Make sure you want to look at the module. You may be choosing body style; You may need the body code (sometimes the third character in the VIN) You may also be asked about certain options, like ZL6. They are on a tag in the glovebox.
10. After that you will be able to play with the Tech2 clone.

IMPORTANT: Sometimes, it’s just problem with candi, as when using on other cars without candi, it’s just perfect. So you should have a good candi such as . It’s just better, but still needs to connect a few times. So I you can buy another card 148. If not totally solved, rewrite the card to 143 and 136. Both work fine. That is, 148 is no good for candi. Could be corrupted software, or the card problem. These cards coming together with Tech 2 are not good sometimes. You’d better but china knock-offs from a man of his word to trust in. Here, obdii365.com is one of them you can go with.

Tech 2 and OPCOM: which is better for Opel steering angle sensor reset?

Here are tips and guides of Opel steering angle sensor (SAS) calibration, incl SAS GM scan tools and FAQs…

What is steering angle sensor:

The steering angle sensor (SAS) is a critical part of the ESC system that measures the steering wheel position angle and rate of turn. A scan tool can be used to obtain this data in degrees. The SAS is located in a sensor cluster in the steering column.

Opel Tech 2 and Op-com, which is better for SAS reset:

With Tech2 you don’t need a PIN code.
Saab doesn’t have PIN code like Opel.

How to reset Opel steering angle sensor:

Tech 2 steering angle sensor calibration:

(source: http://www.obdii365.com/wholesale/tech2-diagnostic-scanner-with-tis2000.html)

Here is the procedure with Tech2:
Calibrating the steering wheel angle sensor
Note
The wheel alignment must be correct before calibration is carried out.
1. Put the wheels straight ahead.
2. Connect the diagnostic tool.
3. Select Steering Angle Sensor Calibration. Follow the instructions displayed.
4. Read and clear diagnostic trouble codes.
5. Test drive the vehicle.

Op-com steering angle sensor calibration:

(source: http://www.obdii365.com/wholesale/opcom-2014v-firmware-1-95.html)

1. 1. Disconnect the battery and the steering angle sensor lose its basic setting
   2. Remove airbag and steering wheel following the usual precautions
   3. Move the center rotor of the CIM to align the 2 triangles
   4. Connect the op-com interface with computer via USB port than install the software
   5. Plug the op-com unit into the vehicle USB port after succeeded installing software
   6.  Op-com will turn out the ESP light but not very first and second time
   7.  Turn on the vehicle ignition switch and start the vehicle.
   8.  Drive in a short distance straight line on a level surface at the speed not higher than 20 km/h.
   9.  When the steering wheel is straight, stop the vehicle with the wheels pointed straight. Make sure the vehicle is not move again.
   10.  Come to the op-com main function menu, select “Op-com Diagnostic”>> Vehicle year “2006”>>Vehicle model “Astra-H”>>Body>>CIM (Steering Column Module. >> Measuring block 3>>Steering Angle Sensor offset – set to 0.00 by slightly moving steering wheel
   11.  Back to the CIM screen, select “Programming”. Enter the security code if the system asks for it. Then click “Yes” when the system accepts the security code.
   12.  Go back to the programming screen, select “Steering angle calibration”, if the system still showed steering angle calibrated, choose “No, choose Activate and waited”. Otherwise, select “Yes” when the system displays steering angle calibrated.
   13.  The ESP light then came on with ignition as normal and went out after a few seconds

FAQs: steering angle sensors (SAS)  

How long have steering angle sensors (SAS) been in use?These sensors have been in use on certain vehicles since the early 1990s, but became commonplace by 1998.

Why does the SAS need to be calibrated or reset after a wheel alignment?Because it is required by the OEM.

When did OEMs begin requiring SAS reset with alignment?Some as early as 2003, others as recently as 2008, though some 2008 models were specified as early as 2002. Hunter’s WinAlign software has always provided vehicle specific screens that advised technicians that special equipment and software would be required to complete the alignment.

Why am I just now hearing that SAS need service?Because many newer on-board systems such as electronic stability control and electric power steering rely on accurate input of the driver’s intentions. This input is provided by the SAS)

Why do some OEMs require SAS reset in conjunction with alignment on only particular models or model year of vehicles?Each OEM has their own specific selection criteria on which vehicles are affected.

Why don’t all OEMs require reset after alignment?Each OEM has its own service requirement criteria. Most OEMs have only added the requirement in the last few years. Some as recently as 2008.

Does the SAS need to calibrated or reset if thrust angle is not changed during the wheel alignment?Yes. Thrust angle is only one of many conditions causing the SAS to report a value other than zero when the front wheels are steered straight-ahead based on the thrust angle.

Why do some SAS reset procedures require the vehicle to be driven a given distance to complete the procedure?Each vehicle manufacturer develops the SAS reset procedure based on the technology and design of the system. In some cases, a test drive is needed for the vehicle’s ECM to verify proper operation. CodeLink will indicate which specific vehicles require a test drive.

Do SAS automatically calibrate themselves after the vehicle has been driven a given distance?On some vehicles, SAS is automatically calibrated; on other vehicles, it is not. In either case, OEM mandates determine whether SAS reset is required after wheel alignment. Always follow the OEM’s recommended service procedures.

What may happen if the SAS requires calibration or reset and the process is ignored?A variety of symptoms may result from a SAS reporting inaccurate information. Examples of such symptoms may be a shutdown of the electronic stability control system, untimely application of individual brakes, steering wheel vibration or a vehicle that drifts of pulls in one direction.

GM Tech 2 works with Hummer: Yes or No?

This is about GM Tech 2 scan tool for Hummer troubleshooting and programming.

Can I have a cheap Tech 2 for Hummer?

Yep. Both the original and HQ clone can work for your car.

Where can I get a working clone at a good price?

http://www.obdii365.com/wholesale/tech2-diagnostic-scanner-with-tis2000.html

Why my Hummer is not shown in the GM vehicle list?

That little short list is incorrect and only shows a few of the earlier than 2007 CAN bus vehicles.

Tech 2 clone for both troubleshooting and programming Hummer?

I’ve used my Tech2 on my 08 many times for troubleshooting not programming

But I think it should be able to program Hummer.

Anyone has good success of Hummer H3?

My H3 has had a CEL on – po452. I checked it with the tech 2. Well it pulls 3 codes, po455 (large evap leak), po442 (small evap leak), and po449 (vent solenoid control).

Tech 2 is possible to program for Hummer H2 above the year 2007… what to do in that case?

Actually it does the programming just fine on newer than 2007 GM vehicles BUT you must pay for an ACDelco TDS subscription for vehicles above 2007 and you would use the CANDI module that comes with many of the Tech2’s for working with CAN bus vehicles. You can subscribe for it.

This is ONLY needed if you want to program or update the software in a module. ALL of the build in diagnostics and testing for vehicles up to 2013 works without the subscription or the older TIS2000 software. You only need those for doing actual programming. The older TIS2000 software – that is what has the programming was discontinued in 2007. TIS2000 does have the actual programming for all vehicles up to 2007. After 2007 GM went to the TDS system.

You can also get a newer style MDI or MDI 2 for diagnostics and programming. The catch with those. They have NO screen or built in software and you must pay for a subscription from from ACDelco TDS to use an MDI.

Other brand units, a very select few can do actual programming and use the pass-through method. NONE have the diagnostics that the actual Tech2 scanner or MDI interface (with the subscription) will have. Check with Autel and see if they have the full diagnostics and re-calibration for the rear air suspension on a Hummer H2. Not going to happen, there is too little demand for them to hack and reverse engineer that particular bit of code in a Tech2 to figure out the diagnostics and then write programming for that for their tool.
