The P1630 fault code refers to the Theft Deterrent Learn Mode Activation. This code is triggered when the Engine Control Module (ECM) receives incorrect immobilizer data from the Body Control Module (BCM). Here’s how it works: The BCM sends pre-release information to the ECM through the serial data circuit.

The ECM then challenges the BCM, and both modules perform a calculation on this challenge. If the calculated response from the BCM matches the calculation performed by the ECM, the vehicle is allowed to start.

After that, the BCM sends the remaining immobilizer data to the ECM. If the immobilizer data sent by the BCM matches the data stored by the ECM, the engine is allowed to remain running. However, if the ECM receives incorrect immobilizer data from the BCM, it sets the P1630 fault code.

This fault code indicates a problem with the theft deterrent system’s learn mode activation.

It’s important to address this issue promptly to ensure the proper functioning of the immobilizer system and prevent unauthorized vehicle access.
