| B1B89:31 | Seat Slide Motor Speed/Position Sensor: No Signal | This DTC sets when the DSM does not receive any signal from the Hall-effect sensor, integral to the horizontal motor. |
| B1B90:11 | Seat Tilt Motor Relay: Circuit Short To Ground | This DTC sets when the DSM detects the front height motor relay (integral to the DSM) is stuck or a short to ground is present in the front height motor output circuit. |
| B1B90:15 | Seat Tilt Motor Relay: Circuit Short To Battery or Open | This DTC sets when the DSM detects the front height motor relay (integral to the DSM) is stuck or a short to voltage is present in the front height motor output circuit. |
| B1B91:31 | Seat Tilt Motor Speed/Position Sensor: No Signal | This DTC sets when the DSM does not receive any signal from the Hall-effect sensor, integral to the front height motor. |
| B1B92:11 | Seat Recline Motor Relay: Circuit Short To Ground | This DTC sets when the DSM detects the recline motor relay (integral to the DSM) is stuck or a short to ground is present in the recline motor output circuit. |
| B1B92:15 | Seat Recline Motor Relay: Circuit Short To Battery or Open | This DTC sets when the DSM detects the recline motor relay (integral to the DSM) is stuck or a short to voltage is present in the recline motor output circuit. |
| B1B93:31 | Seat Recline Motor Speed/Position Sensor: No Signal | This DTC sets when the DSM does not receive any signal from the Hall-effect sensor, integral to the recline motor. |
| B1B94:24 | Seat Height Up Switch: Signal Stuck High | This DTC sets when the DSM detects the rear height control switch is stuck in the up position or a short to ground is present on the rear height switch input circuit for greater than 30 seconds. |
| B1B95:24 | Seat Height Down Switch: Signal Stuck High | This DTC sets when the DSM detects the rear height control switch is stuck in the down position or a short to ground is present on the rear height switch input circuit for greater than 30 seconds. |
| B1B96:24 | Seat Slide Forward Switch: Signal Stuck High | This DTC sets when the DSM detects the horizontal control switch is stuck in the forward position or a short to ground is present on the horizontal switch input circuit for greater than 30 seconds. |
| B1B97:24 | Seat Slide Backward Switch: Signal Stuck High | This DTC sets when the DSM detects the horizontal control switch is stuck in the rearward position or a short to ground is present on the horizontal switch input circuit for greater than 30 seconds. |
| B1B98:24 | Seat Tilt Up Switch: Signal Stuck High | This DTC sets when the DSM detects the front height control switch is stuck in the up position or a short to ground is present on the front height switch input circuit for greater than 30 seconds. |
| B1B99:24 | Seat Tilt Down Switch: Signal Stuck High | This DTC sets when the DSM detects the front height control switch is stuck in the down position or a short to ground is present on the front height switch input circuit for greater than 30 seconds. |
| B1C00:24 | Seat Recline Up Switch: Signal Stuck High | This DTC sets when the DSM detects the recline control switch is stuck in the up position or a short to ground is present on the recline switch input circuit for greater than 30 seconds. |
| B1C01:24 | Seat Recline Down Switch: Signal Stuck High | This DTC sets when the DSM detects the recline control switch is stuck in the down position or a short to ground is present on the recline switch input circuit for greater than 30 seconds. |
Possible Causes
- Fuse
- Wiring, terminals or connectors
- Seat control switch
- Horizontal motor
- Seat track
- Seat backrest
- DSM
Visual Inspection and Diagnostic Pre-checks
- Verify RJB fuse 9 (25A) is OK.
