Question about 1995 Saab 900

1 Answer

Code -ECM I have the code, thats not the problem. The problem is the disconnect from the ECM. I need to know how to reconnect the Code Request system back to the ecm so that I can put at least put the Radio code in and get my radoi to come back on? And all I know is what the mechanic told me was that he went under the dashboard to disconnect the Code System Request!

I see - I guess I didn't quite follow what you said. I have a friend at work who is a "Saab guy" and I'll ask him for you how to do this. Soon as we talk, I'll post up the information if he can give it to me.

    I did ask him about it and he had no clue what I was talking about, which surprises me because he's a Saab ninja when it comes to servicing. I'm not sure what to tell you honestly. I'll take a walk through the web and see what I can find out and will reply again here to let you know what, if anything, I find.

I have a Clifford 3102x two year old I disconnected battery on reconnect car won't start. Central locking works arms disarms but engine doesn't not turn over? Just red ignition light on dash.

The security code for the ecm needs to be reset also the ecm may need to be reflashed as leaving the battery disconnected has been known to wipe or corrupt the ecm
The ecm is the engine control module that contains the security system and the operating system for the correct running of the engine
Also get the starter motor solenoid checked
Refreshing means you get the ecm reloaded with the engine control software and the keys relearned to the security system

2003 saturn L300 p1780

DTC P1780 (3.0L (L81))

To improve shift feel, the transmission control module (TCM) may request that the engine control module (ECM) reduce engine torque during shift events. When such a request is received, the ECM responds by retarding the base ignition timing and notifying the TCM that the request has succeeded. If the ECM is unable to comply with the request, the ECM sends the TCM a message that the request has failed.
The torque reduction request is sent to the ECM through a communication network called the controller area network (CAN). Two circuits are used to communicate CAN data between the ECM and TCM. A fault in the CAN will not cause DTC P1780 to set by itself. If a CAN fault occurs, other DTCs will set before DTC P1780.
When the TCM receives a torque reduction failure message from the ECM, then DTC P1780 will set. DTC P1780 is a type C DTC. Take your pick of which you think this code is for , this or the TSB - technical service bulletin.

How can i tell if my computer has went bad on my 1997 chevy lumina 3.1?

Patrick, car places refer to the computer as the Engine Control Module, or the ECU.
According to "If you are having a bunch of codes that don't mean anything then you might have an ECM going bad, but first you need to make sure all of the powers and ground paths are clean and tight, then clear the system and run a relearn for the ECM, usually about 20 minutes driving normally will do this, if the check engine turns on again then have the codes read and repost back here for further diagnosis. The computer or ECM controls all of the fuel delivery, spark timing and on some vehicles the charging system, that is why it needs a good power and ground pathway, ECM's do fail but I have found that a lot of problems are related to either a power supply or ground, this can be very time consuming. "

"The ECM will remember that there was a failure and still have a light and a code, you need to clear the system before trying to retest, the best way to clear it is to disconnect the negative battery terminal, turn on the headlights, wait 30 seconds, turn off the headlights, reconnect the battery , start en"gine and drive normally, the ECM should relearn in about 20 minutes of driving unless there is still a hard fault then the check engine light will turn right back on and you can get the code..
One of the cheapest ways to replace an ECM is to pull one out of a wrecking yard.

Hi my A B S warning light is on i fixed the car myself but now cant get the light to go off can anyone help thanks

If you can't get it to reset by resetting the ECM then you still have a fault in the system that needs to be addressed. You can reset the ECM by disconnecting teh negative battery cable for 60 seconds then reconnecting it. Make sure you have the lock code for the radio written down before you try this as you will most likely have to re-enter that code after doing the rest.

What do these codes mean needs to be fixed. P1529 and P1723. Thank you

The TCM can request activation of the MIL lamp Via a communication line to the ECM. This is only a request from TCM to ECM to turn the MIL on. The fault code is stored in the TCM. Select Transaxle system on the Scantool and monitor DTC related automatic transaxle system.
DO ALL REPAIRS associated malfunction with A/T.
Is that all?

P1529 TCU Request for MIL On / Freeze Frame to ECU via CAN
1. This is only a request from TCM to ECM to turn the MIL on. The fault code is stored in the TCM. The Freeze Frame Data is stored in the ECM under the P1529 request code. Be sure to retrieve freeze frame data before clearing code P1529 from ECM. 2. Check the transaxle system.

What you probably have to do is enter a security code to unlock the radio - it's an anti-theft idea done by Saab, that Audi and BMW and others also do, to try and make it harder to re-sell stolen radios.

Go to the dealer with photo ID, the title to the car, and your registration - that way you prove who you are and that you own the car, and they can look up the code for you. They may charge you up to an hour's labor for this. Make sure they give you the code though, and don't just have a technician put it in. If you don't get the code from them, you'll have to pay them the next time too.
