Safelock on 2006 Pontiac Torrent. Randomly prevents starting. Seems to reset after a day or so. Is there a way to disable


It is the passlock system not safelock An you can't just disable it . It is software program into the BCM - body control module an the PCM - powertrain control module .Simply disconnecting the wires from the ignition to the BCM will render your vehicle useless . If an when the security symbol light is on you need to have it checked for DTC'S - diagnostic trouble codes . A GM dealer ,Chevy , Buick , Cadillac etc.... we know Pontiac is no longer around. Everything will work except the PCM will not let the fuel injectors work .
Passlock?"¢ System
The theft deterrent system has been incorporated into the body control module (BCM). The theft deterrent system is provided in order to prevent the vehicle operation if the correct key is not used in order to start the vehicle. The ignition key allows the lock cylinder to rotate. The cylinder rotation produces an analog voltage code in the Passlock?"¢ sensor. This voltage code is received by the BCM. The BCM compares the voltage code to the previously learned voltage code. If the codes match, a serial data message is sent from the BCM to the powertrain control module (PCM). The message enables the fuel injector operation.
The design of the Passlock?"¢ system is to prevent vehicle theft by disabling the engine unless the ignition lock cylinder rotates properly by engaging the correct ignition key. The system is similar in concept to the Passkey system. However, the Passlock?"¢ system eliminates the need for any key mounted components. The components of the Passlock?"¢ system are as follows:
?€¢
The ignition lock cylinder


?€¢
The ignition switch


?€¢
The Passlock?"¢ sensor


?€¢
The BCM


?€¢
The security indicator


?€¢
The PCM

How do I reset 2002 Chevy venture check engine light? !


First of all the check engine code you can reset by disconecting negative terminal on your baterry. If you have scaning tool you can do that easy. If not go to the Advanve Auto Parts or Auto Zone they will reset it for you at no charge. Secondly you check engine light stays on since the PCM trows out trouble code. Check that also to se what type of code you have. It could cost you a lot of money if you don't address it on time. Good Luck.

I have trouble starting my van and later on the check light came on (P1607). The car can no longer start but sometimes when I fiddle with the battery it would start up again and when it does it runs fine....


P1607 means "powertrain control module (PCM) internal circuit malfunction". According to the factory service manual, a low battery condition can cause this. This code can also pop up after the battery has been jump started.

You need to reset the PCM. To do this, turn the ignition switch off. Remove the No. 13 fuse (7.5Amp) from the passenger's under dash fuse/relay box for at least 10 seconds. Put the fuse back in. That should complete the reset.

Now to check again for the code: turn the ignition switch to on (not start.) Wait 30 seconds. If the check engine light stays OFF, turn the ignition switch off and wait 10 seconds. Turn the ignition switch back to on (not start). Wait 10 seconds. If the check engine light stays OFF, you had an intermittent fault and it has now been reset--everything is fine. If the check engine light comes back on during these checks, have the code that set read out. If the code is P1607 again, then you may have to have the PCM tested at the dealership for an internal fault.

How to reset the check engine on a 208 chevy


Just disconnect the battery (negative terminal) and turn the headlight switch on for about 15 minutes. This should reset the PCM. Otherwise go to Advance and have them hookup the code reader and reset the codes. Thanks

2002 Chev Siverado,2500hd duamax dielsel. Changed the two batteries becuase the others died. Now I cannot start the engine. The engine truns over good. The security light flashes.


It sounds like the anti theft pass key's have most it's memory and needs to be reset. Try this, it takes about 30 min to do. 30-Minute Learn Procedure 1. Turn ON the ignition, with the engine OFF. 2. Attempt to start the engine, then release the key to ON; the vehicle will not start. 3. Observe the SECURITY tell tale light. After approximately 10 minutes, the light will turn OFF. 4. Turn OFF the ignition switch, and wait 5 seconds. 5. Repeat steps 1 through 4 - two more times - for a total of 3 cycles of 10 minutes. 3x10 = 30 minutes. The vehicle is now ready to relearn the Passlock Sensor Data Code and/or passwords on the next ignition switch turn from OFF to CRANK Important: Turn the Ignition Switch OFF. The vehicle learns the Passlock Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle. 6. Start the engine. The vehicle has now learned the Passlock Sensor Data Code and/or password. 7. With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100 ignition cycles. Without a scan tool you may have momentary starter interruptions while history clears itself. Good luck and hope this helps, keep me posted, be glad to help
