Circuit Description

The body control module (BCM) provides an output to the driver switch assembly through the passenger door lock switch lock control circuit for controlling automatic door lock and keyless entry lock functions.

Conditions for Setting the DTC
    • The BCM detects a short to ground on the passenger door lock switch lock control circuit for greater than 60 seconds.
    • The BCM detects a short to battery on the passenger door lock switch lock control circuit for greater than 1 second.

Action Taken When the DTC Sets
    • The BCM stores DTC B3152 or B3153 in memory.
    • The BCM will disable the output and all operations of the output until the fault no longer exists.

Conditions for Clearing the DTC
    • The BCM no longer detects the short to ground on the passenger door lock switch lock control circuit for greater than 60 seconds.
    • The BCM no longer detects the short to battery on the passenger door lock switch lock control circuit for greater than 1 second.
    • 100 consecutive ignition cycles have been recorded without the DTC being detected.
