Circuit/System Testing

  1. Verify that there are no DTCs in the BCM.
    • If there are any DTCs in the BCM, diagnose those DTCs first.
  2. Ignition ON. Monitor the Park Switch (Auto) in the BCM Keyless/Remote Start Data with a scan tool. Shift the transmission range selector in and out of Park. Verify that the scan tool display changes between Active and Inactive.
    • If the Park Switch (Auto) does not change between Active and Inactive, test or repair the BCM park signal circuit.
  3. Ignition ON. Monitor the Column Lock Relay Signal in the Chassis Data with a scan tool. Shift the vehicle into Park and turn off the ignition. Verify that the scan tool display changes from Off to On.
    • If the BCM Column Lock Relay Signal does not change between OFF and ON, test or repair the steering column lock control circuit.
    • If the steering column lock control circuit is OK, test or replace the BCM.
  4. If all circuits test normal, replace the SCLCM.
