Forum rules


When you put a new thread up in the Workshop please put your car's year and model in the title, along with just a brief indicator of the problem.

Car Year - Car Model: Brief description of issue. EXAMPLE- 1999 9-3. Problems starting when hot

Please also add as much information as you can about the problem, to your post.

This will help us to help you, without having to ask basic details such as what car you have.

Threads with non-compliant titles will be moved to The Pit Lane (in which no replies can be posted, but the OP can edit the thread - upon which the thread will be released to the workshop forum)

Nb. Generic thread titles for truly generic issues that genuinely are not model or variant specific (such as "how do I change the spring in an forge wastegate actuator") are acceptable

**The first 5 posts for new users require individual moderator approval (which they will only get it if they are in line the rules of the forum). Please be patient and allow time for that to happen, and avoid duplicate postings.**

A friend has a 1995 9000 CSE which has failed the MOT due to warning lights for the airbags and ABS. The car cannot be driven to the Saab specialist (70 miles each way) so he has asked me if I know someone local. Now, I have a genuine Tech 2 but apparently the only plug in point is under the drivers seat and is green in colour and roundish probably 6 pin. I do not have a plug that would fit it in my tech 2 and the car probably pre dates tech 2 anyway. The owner has been told it is an ISAT system. Can anybody tell me what I need to access this and does anybody in the Aberdeen area have one? My knowledge of electricals is limited to knowing that they are powered by smoke, once it is released the component no longer works!

If you have a Tech-II you should also have the adapter lead to plug into the sockets under the seat. The ECU is OBDII compliant because its the same one that is used on the later cars. All the other in-car modules will work with Tech-II as well but you might need to plug into the Black socket instead.

There should be 1 or 2 rectangular plugs under the front edge of the seat, one green, one black, both the usual saab 2*4 pin H block connectors..

One is for ECU, one is for other car features.

Also you need V44 or earlier Tech II code.

Thanks guys, will have a look on a scrapper in the morning if it is a bit drier to see what is what then go and look at his car which is in the village a few miles away.

The adapter lead for the ISAT sockets is optional with Tech II. Not every official Tech II kit will have it. The ECU will only support OBDII after 1996. Prior to that the software didn't support it and in fact neither did the hardware in the respect that it didn't have the CPU power to run the OBDII software. Trionic 5.5 units that support OBDII have a 20MHz processor while earlier ones have a 16MHz processor. Even with that, OBDII doesn't work at higher RPM.
It doesn't matter, though, since Tech-II doesn't need OBDII to work.

As stated above, you will need the earlier Tech-II software to talk to a 9000. And the ISAT cable. The ABS fault light will clear itself once the fault is fixed. The SRS fault light must be cleared explicitly after fixing the fault.

If you don't have Tech-II with the correct cable and software then you will need to borrow an ISAT. We borrowed one to diagnose the SRS light on GirlySaabFan's '94 CSE Auto. That turned out to be due to one of the two SRS warning light bulbs being blown. Once fixed, we reset the light and all was fine :)

When I had 9k's the main reason for an SRS warning coming on was that the heater had leaked down onto the SRS ECU carefully located below it and corroded the terminal pins. Easiest way to cure it was to replace with another OK SRS ECU which automatically put the light out. (Then tape a sheet of polythene over the ECU to stop it happening again).

Later cars from about 1995 onwards had a plastic cover over them to stop this. There may have been a recall to retrofit it as well?
