DTC Fault Trigger Conditions 

DTC Description Fault Trigger Conditions
B1375:11 Steering Column Tilt Motor: Circuit Short To Ground This DTC sets when the BCMB senses the tilt motor current draw has exceeded a specified threshold. When this DTC sets, the BCMB disables the circuit until the ignition is cycled.
B1375:15 Steering Column Tilt Motor: Circuit Short To Battery or Open This DTC sets when the BCMB senses the tilt motor circuit voltage is above a specified threshold when the driver is active. This DTC will also set if the BCMB senses the tilt motor circuit voltage current draw is less than a specified threshold when the driver is active. When this DTC sets, the BCMB disables the circuit until the ignition is cycled.
B137E:11 Steering Column Telescope Motor: Circuit Short To Ground This DTC sets when the BCMB senses the telescope motor current draw has exceeded a specified threshold. When this DTC sets, the BCMB disables the circuit until the ignition is cycled.
B137E:15 Steering Column Telescope Motor: Circuit Short To Battery or Open This DTC sets when the DSM senses the telescope motor circuit voltage is above a specified threshold when the driver is active. This DTC will also set if the BCMB senses the telescope motor circuit current draw is less than a specified threshold when the driver is active. When this DTC sets, the BCMB disables the circuit until the ignition is cycled.

    • Connect the BCMB electrical connectors.

    • Operate the system and determine if the concern is still present.

    Is the concern is still present? 

    Yes  CHECK OASIS for any applicable service articles: TSB, GSB, SSM, or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, INSTALL a new BCMB. REFER to: Body Control Module B (BCMB) .
    No  The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
