B2515
DTC B2515Circuit Description
The SCLCM controls the column lock motor using an internal lock relay, an internal unlock relay, and an internal lock enable relay. The lock and unlock relays provide a low input to the column lock motor. When the column needs to be locked the lock enable relay will energize the lock relay, which provides a high input to the lock side of the motor, energizing the motor to lock the steering column.
When the SCLCM receives the low input from the BCM the internal lock enable relay is energized and provides a high input to the lock side of the column lock motor. The unlock side of the column lock motor is grounded through the internal unlock relay within the SCLCM. The column lock motor will send an input back to the SCLCM indicating the motor is energized for the locked position. This results in the locking of the steering column.
Conditions for Running the DTC
^ DTCs B0005, B 1000, B 1327, B 1328, or B2907 are not set as current.
^ The condition must be present for 300 ms.
^ The condition must be present for 5 consecutive ignition cycles for a locking fault or one ignition cycle for an unlocking fault.
Conditions for Setting the DTC
This DTC will set when the SCLCM checks for a valid feedback signal, but the feedback is not what was expected. This indicates a fault in the motor feedback switch/motor circuit.
Action Taken When the DTC Sets
^ Stores a DTC B2515 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 motor feedback switch/motor 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.
Test Description
The numbers refer to the step numbers on the diagnostic table.
2. During the steering column electronic lock operation, listen for an audible click. Repeat the commands as necessary.
3. This test determines if the steering column electronic lock feedback circuit is operating properly.
