Re: No Start condition and No PCM communications

Now that I know the year of the car, the PO1637 is still alternator and battery related. An improper voltage level has been detected on the charge indicator control circuit. This code can be erased by the scanner and you can see if it set the code again before you diagnosis the problem further.

The B1000 code is set within the SRS module and would probably need to be replaced, not the air bags. 

It might be cheaper to have a certified mechanic diagnosis the car instead of replacing parts at random. It is also very dangerous messing around with air bags if you don't have the knowledge of the SRS Airbag system. Just a spark of static electricity or probing the wrong wire could set of an air bag without warning causing bodily injury.

Re: No Start condition and No PCM communications

The battery and alternator were checked locally and no issues. Maybe it is all from sitting on the lot for a while? The SRS module, where is it located on this vehicle and shouldn't it be a simple and safe replacement job?

Re: No Start condition and No PCM communications

Clear all of the codes first and see which codes come back.

To replace the module you first have to disable the Air Bag system. The interior has to be removed which includes the seats and carpet and center console if equipped. The module is in the center of the vehicle. If the area is not clean, wet in any way or rusty which can cause the improper installment of the module could set off the air bag system.

This is not a system to mess around with. If you don't have the proper tools, working environment and scan tool and if the procedure is compromised by shock to the module or improper torque of the module could set off the system causing bodily injury.

It may be cheaper to have the SRS system checked out by a certified mechanic for this repair.

Re: No Start condition and No PCM communications

The instructions for adding a key FOB for the 2002 Grand Prix didn't work from the 1999 one. Are there any more specific instructions that you can find? Thank you...

Re: No Start condition and No PCM communications

The program procedures are almost identical. You can only program a total of 4 FOBs for the vehicle. You may have to erase all of the programmed ones and install the ones you have.

This is the program procedure for the 1999 Pontiac Grand Prix.

Turn the ignition switch from the ACC position to the OFF position, then back to the ACC position within 1 second. This action causes the BCM to enter the diagnostic/program mode. The BCM may flash and chime Diagnostic Trouble Codes (DTCs) . The number of flashes and chimes equals the DTC number. If there are DTCs in memory, record the DTCs.

Open and close any vehicle door. You should hear a chime if you are in the diagnostic/program mode.

Press and hold the lock and unlock buttons at the same time on the keyless entry transmitter for 14 seconds.

At the 7-second mark, you may hear a chime. This chime feedback indicates that the transmitter has been resynchronized.

Continue holding the lock arid unlock buttons until hearing another chime sound at the 14-second mark. This chime feedback indicates that the transmitter has been programmed successfully.

Repeat step 5 for the rest of the transmitters (for a total of 4 transmitters).
Exit the BCM diagnostics/programming mode by turning the ignition switch to the LOCK position.

Reinstall the MALL PGM Fuse.

Re: No Start condition and No PCM communications

Let me ask again, what are the programing procedure for a 2002 Pontiac Grand Prix GT 3.8L ???

I could not program the new FOB from the old instructions.

Re: No Start condition and No PCM communications

This is the programming procedure for the 2002 Pontiac Grand Prix 3.8 from the Alldata website.

IMPORTANT: All transmitters which are to be recognized by the remote control door lock transmitter (RCDLR) must be programmed in a single programming sequence. If the system is placed in program mode it will erase all previously programmed transmitters upon the receipt of the programming signal from the first transmitter. Up to four transmitters can be programmed. Do not operate or program the transmitters in the vicinity of other vehicles that are in the keyless entry program mode. This prevents the programming of the transmitters to the incorrect vehicle.

Remove the ignition key from the ignition lock cylinder.
Close all of the doors.
Remove the MALL PGM fuse from the fuse block.
Insert the ignition key into the ignition lock cylinder.
Turn the ignition to ACC. The body control module (BCM) will perform the following in order to identify the type of BCM installed in the vehicle:
Flash the seat belt indicator 1, 2, or 3 times.
Chime 1, 2, or 3 times.
Turn the ignition to OFF, and then back to ACC within 1 second. The BCM may begin to chime and flash diagnostic trouble codes (DTC's). If the BCM has stored any DTC's, refer to Diagnostic System Check - Body Control System in Body Control System.
Open and then close any vehicle door. The BCM will chime in order to confirm that the programming mode has been entered.
Press and hold the transmitter LOCK and UNLOCK buttons simultaneously for approximately 14 seconds.
IMPORTANT: After approximately 7 seconds the BCM will chime once to confirm that synchronization has been completed. After approximately 14 seconds the BCM will chime a second time to confirm that the programming has been completed.

Repeat the previous step in order to program each additional transmitter.
Remove the ignition key from the ignition lock cylinder.
Install the MALL PGM fuse into the fuse block.
Operate the functions of each transmitter in order to verify correct system operation.

There is also a resynchronization procedure, I listed it below.

Resynchronization may be necessary due to the security method used by the remote keyless entry system. The transmitter does not send the same signal twice to the remote control door lock receiver (RCDLR).
The RCDLR will not respond to a signal that has been sent previously. This prevents anyone from recording and playing back the signal from the transmitter.
Resynchronization may be necessary under the following conditions:
The battery in the transmitter is very weak.
The battery in the transmitter was replaced.
The battery in the vehicle has been in a low or no charge condition for an extended period of time.
In order to resynchronize the transmitter with the RCDLR, perform the following steps:
Stand within 1.5 meters (5 ft) from the vehicle.
Simultaneously press and hold the LOCK and UNLOCK buttons on the transmitter for 7 seconds . The horn should chirp in order to confirm synchronization.
