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 instrument panel module (IPM). 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 IPM and the transmission shift select switch park signal circuit is low, DTC B0005 will set.

This vehicle has DTCs which include DTC symptoms. For more information on DTC symptoms, refer to DTC Symptom Description in Vehicle DTC Information.
DTC Symptom | DTC Symptom Descriptor |
|---|---|
08 | 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 IPM 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
| • | 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. |
