Saab 2006 Rear Window Express Program Retrofit with Tech2

 Rear window "express-up" retrofit

So, as we all know, in 2006 and newer models, SAAB got rid of the express-up feature for the rear door windows when controlled from the driver's switchpack. Call it GM "decontenting" or maybe due to societal stupidity and potential lawsuits (?), whatever the reason, I really like the feature and it's always driven me nuts that the switches are there but don't work as they should. It's like dangling candy in front of a baby! :evil: I probably wouldn't even have thought to do this if SAAB hadn't kept using the driver's switchpack with double-detent rear window buttons! But they did. And I most always drive with my windows down, especially the drivers window and the window directly behind me (so I don't get buffeted in the face, try it sometime!).

So, with that said, here's how to retrofit express-up windows into your 2006+ sedan or Combi.

You'll need the following parts:

- Rear left window motor (6-pin version), part number 12788801
- Rear right window motor (6-pin version), part number 12788802

- Rear left window regulator (pinch-protection version), part number 12793730
- Rear right window regulator (pinch-protection version), part number 12793731

- Rear left door harness (w/6 pin motor connection), part number 12785580
- Rear right door harness (w/6 pin motor connection), part number 12785581

- GM Tech 2, CANdi box, security access with TIS2000 subscription

- Patience and a good chunk of time

Everything is literally plug and play once you've sourced the correct parts. Remove and replace the regulators, motors, and harnesses. Not hard to do at all. 

The only exception is if you have rear door speakers like I do (apparently not that common?). You'll have to transplant the speaker harness into the new harness to keep the speakers. Couple of thoughts on this: rear door speakers really don't do a whole lot, so it's not a deal-breaker if you don't feel like doing this. Or if you want, you can just make a new harness for the speakers. I wanted to do it factory-style, so I moved the harness, moved the pins, re-wrapped the harness, etc.

After everything is in, it won't work. Don't worry! You still need to program the RLDM and RRDM (rear left and right door modules). In comes the Tech 2:

1. Get security access.
2. Diagnostics, select year and car, select "All".
3. Add/Remove.
4. Remove both the RLDM and RRDM.
5. Add the RLDM and RRDM, specify "With Anti-Pinch Motors". Also select "EU" for Market just in case. Here's the tricky part, where I almost gave up! DO NOT SELECT THE YEAR OF YOUR CAR. It won't work. You have to "trick" the system. Select 2004 when it asks the year of the car.
6. Once the modules have been added back in, calibrate the rear window pinch protection just as you would the front windows. You'll hear a "beep" from the SID letting you know the windows have been calibrated.
7. Enjoy your express-up windows!

This may seem trivial but I literally yelped when it finally worked. 

 What good are auto-up windows if only 2 of the 4 work?

Hope that helps anyone else looking to do this!

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.

How to set up GM Tech2 clone scanner?

As titled, here’s little guide on set up a GM tech2 clone scan tool.

STEP 1
Buy a GM tech 2. The Tech 2 remains an essential tool through at least the 2010 model year. Clones are available from $200-$350.

SP23-1 (no case) verify that it includes the 32 MB card
SP23-B3 no case, with 32 MB card and TIS2000 software
SP23-C plastic box, with 32 MB card , TIS2000 and candi interface

It should arrive within a week (took 5 days for me) from Hong Kong.

Some prefer SP23-B3, no case. I bought the sp23-c with candi. The unit comes with a CD and stickers.  You made your choice.

STEP 2

Get out an old laptop or buy one online e-shop. It needs Windows XP and a serial port. I run a Dell D630. You can try USB to serial adapters or newer versions of Windows but do you want to mess around with getting old software to run on new computers?

STEP 3

Download cracked TIS2000 from the software on GM forums or use the CD in package and install it on the laptop.

STEP 4

The PCMCIA card comes pre-installed in the gm Tech2. It also comes with a bunch of adapters. You find the one that hooks under the dash. Connect that to the Candi module (that comes with the TEch2) and connect it under the dash. The candi module connects to the tech2. Turn on the tech 2 (the obd2 powers it, no need for wall or cigarette lighter power) and you can read DTCs and stuff.

STEP 5

Now if you want to make changes (such as comfort close or whatever you want to do) there is a menu item on the tech2 that says “Common Adjustments”. Go in there and pick the one you want. Hit ok and then the Tech2 will say it needs security access and tells you what to do to get it (which is basically disconnect the tech2….yes it powers down…and hook up the tech 2 via ethernet cable that is supplied that hooks into a ethernet/serial connector that is also supplied that you hook into the laptop.) Connect the AC adapter to the wall to power the Tech2. You fire up the TIS2000 software on the laptop and on the main screen it says “Get Security Access”. Click on that and it communicates with the Tech2. Click through a few screens and a minute later and it says Level 1 access granted. You unhook the tech2 from the laptop and head back to the car and go back in and change things to your hearts content. Where before it would ask you to get security access you don’t need to anymore.

To make things even easier instead of disconnecting the tech II from the car and having to power it while it communicates with the laptop (the AC adapters are flaky apparently) I just run an extension cord out to my car for the laptop. Disconnect the tech2 from the car when it prompts you to, reconnect it to the obd2 for power, and also to the laptops serial port. Do everything all connected up. It gets a bit crowded in there with a laptop and tech2 and cables, but they can just sit on the passenger seat.
