B0005

DTC B0005

Circuit Description
The steering column lock control module (SCLCM) receives a discrete input from the automatic transmission shift lever and a serial data input from the body control module (BCM). 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. The SCLCM compares the serial data input to the discrete input. If the SCLCM receives a column lock enable command from the BCM and the transmission shift select switch park signal circuit is low, DTC B0005 will set.

DTC Descriptor
This diagnostic supports the following DTC:
DTC B0005 In Park Switch

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
^ DTC B0005 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
^ DTC B0005 is stored in the SCLCM memory.
^ The SCLCM will command the driver information center (DIC) to display the Service Column Lock Now message.

Conditions for Clearing the MIL/DTC

Steps 1 - 6:

^ 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.
