Pinpoint Test D : The Adjustable Steering Column Is Inoperative In One Or More Directions
Refer to Adjustable Steering Column for schematic and connector information.
Normal Operation and Fault Conditions
REFER to: Steering Column - System Operation and Component Description .
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. |

Yes GO to D5 No REPAIR the circuits. - Measure:
- D5 CHECK THE ADJUSTABLE STEERING COLUMN TILT MOTOR OPERATION
- Connect Adjustable Steering Column Tilt Motor C2250.
- Connect a fused jumper wire:
Positive Lead Measurement / Action Negative Lead Positive battery terminal C2602A-2
- Momentarily connect a fused jumper wire:
Positive Lead Measurement / Action Negative Lead C2602A-5 Ground
Does the tilt motor move the steering column when the fused jumper wire is connected to ground?
Yes GO to D6 No INSTALL a new adjustable steering column tilt motor. REFER to: Steering Column Tilt Motor . - D6 CHECK THE ADJUSTABLE STEERING COLUMN TELESCOPIC MOTOR OPERATION
- Connect Adjustable Steering Column Telescope Motor C227.
- Connect a fused jumper wire:
Positive Lead Measurement / Action Negative Lead Positive battery terminal C2602A-6
- Momentarily connect a fused jumper wire:
Positive Lead Measurement / Action Negative Lead C2602A-1 Ground
Does the telescopic motor move the steering column when the fused jumper wire is connected to ground?
Yes GO to D7 No INSTALL a new power adjustable steering column telescopic motor. REFER to: Steering Column Telescopic Motor . - D7 CHECK FOR CORRECT BCMB (BODY CONTROL MODULE B) OPERATION
- Disconnect and inspect all BCMB electrical connectors.
- Repair:
- corrosion (install new connector or terminal - clean module pins)
- damaged or bent pins - install new terminals or pins
- pushed-out pins - install new pins as necessary
- 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.
