The P1632 fault code refers to the Theft Deterrent Start Disable Signal Receiver. This code is related to the vehicle’s theft deterrent system, which includes the Engine Control Module (ECM), Powertrain Interface Module (PIM), and Body Control Module (BCM).

The theft deterrent system is designed to prevent unauthorized vehicle operation by authenticating the security code 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 ensure 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 P1632 fault code indicates a problem with the receiver that receives the theft deterrent start disable signal.
