Circuit Description

The first input the module needs to see is the vehicle in the park position (automatic transmission shift lever). When the shift lever is in the park position, the switch internal to the automatic transmission shift lever closes sending a high input to the SCLCM.

Conditions for Running the DTC
    • DTCs B1327 or B1328 are not set as current.
    • The condition must be present for 300 ms.
    • The condition must be present for 5 consecutive ignition cycles.

Conditions for Setting the DTC
    • This DTC will set when the SCLCM receives a column lock enable command from the BCM and the transmission shift select switch (park) signal circuit is low.
    • There is a short to ground, or an open in the transmission shift select switch (park) signal circuit.

Action Taken When the DTC Sets
    • Stores a DTC B0005 in the SCLCM memory.
    • The SCLCM will command the Service Column Lock Now to turn ON in the DIC.

Conditions for Clearing the MIL/DTC
    • The SCLCM no longer detects a malfunction in the transmission shift select (park) signal circuit.
    • A history DTC will clear after 50 consecutive ignition cycles if the condition for the malfunction is no longer present.
    • Use a scan tool.
