DTC Descriptors

DTC B2897 02: Steering Column Lock Motor Lock Circuit Short to Ground

DTC B2897 05: Steering Column Lock Motor Lock Circuit High Voltage/Open

Diagnostic Fault Information

Circuit	Short to Ground	Open/High Resistance	Short to Voltage	Signal Performance
Steering Column Lock Motor Lock Signal	B2897 02	B2897 05	B2897 05	—

The vehicle theft deterrent subsystem provides the capability to lock or unlock the steering electrically. The steering column lock control module is allowed to unlock when power mode transitions to a non off power mode and an authenticated driver identification device is present. Once the column is unlocked, a crank request can be allowed.

Conditions for Running the DTC

•	The ignition is in OFF, ACCESSORY or RUN position.

•	The system voltage is between 9–16 V.

Conditions for Setting the DTC

B2897 02

The steering column lock enable input circuit is shorted to ground.

B2897 05

The steering column lock enable input circuit is open or shorted to battery.

Action Taken When the DTC Sets

•	DTC B2897 is stored in the steering column lock control module memory.

•	The steering column lock control module will command the driver information centre to display the service column lock warning message.

•	The steering column lock control module indicator is ON.

Conditions for Clearing the DTC

The steering column lock control module has received a lock command and detects no longer a malfunction in the steering column lock circuit.

Circuit/System Testing

Ignition OFF, disconnect the harness connector at the K60 Steering Column Lock Control Module.
Test for less than 10 Ω between the ground circuit terminals 6 and 7 and ground.

⇒	If greater than the specified value, test the ground circuit for an open/high resistance.

Verify that a test lamp illuminates between the B+ circuit terminal 5 and ground.

⇒	If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.

Ignition ON, verify that a test lamp illuminates between the ignition circuit terminal 3 and ground

⇒	If the test lamp does not illuminate, test the ignition circuit for a short to ground or an open/high resistance.

Test for less than 0.3 V between the control circuit terminal 4 and ground.

⇒	If greater than the specified value, test the control circuit for a short to voltage.

Disconnect the connector at the K84 Keyless Entry Control Module.
Test for less than 5 Ω between the K60 Steering Column Lock Control Module circuit terminal 4 and the K84 Keyless Entry Control Module circuit terminal 1.

⇒	If greater than the specified range, test the control circuit for a open/high resistance.

If all circuits test normal, test or replace the K60 Steering Column Lock Control Module. If the DTC resets replace the K84 Keyless Entry Control Module.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
