P1677 Fault Code: Understanding The Description And Troubleshooting Steps
The P1677 fault code relates to the immobilizer function deactivation in the vehicle theft deterrent system. This system consists of the Engine Control Module (ECM), Powertrain Interface Module (PIM), and Body Control Module (BCM).
Its purpose is to prevent unauthorized vehicle operation by authenticating security codes programmed into these modules. When the ignition is turned on or the door is unlocked with the remote key, the BCM and key exchange security data to verify the correct key is being used. Once the correct key is confirmed and the ignition is turned on, the PIM and BCM exchange data to confirm the correct BCM and PIM are being used. After confirming the correct key, BCM, and PIM, the PIM and ECM exchange data to allow the vehicle to start. The data exchange processes involved in this authentication use encrypted data exchanges between each of the devices.
The P1677 fault code indicates a problem with the immobilizer function deactivation, which may require further diagnosis and repair to ensure proper vehicle operation.
FAQ
