DSMDTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B14CB:11 | Seat Height Rear Position Feedback: Circuit Short To Ground | If a short to ground condition is present on the affected motor's position sensor (Hall-effect) feedback circuit, the DTC is set. After a DTC is set, a memory recall is not possible but the seat control switch can operate the associated motor in two-second increments. |
| B14CB:12 | Seat Height Rear Position Feedback: Circuit Short To Battery | If a short to voltage condition is present on the affected motor's position sensor (Hall-effect) feedback circuit, the DTC is set. After a DTC is set, a memory recall is not possible but the seat control switch can operate the associated motor in two-second increments. |
| B14CE:31 | Seat Horizontal Motor Output: No Signal | During self-test, the DSM attempts to operate the appropriate seat track motor and uses the motor's position sensor to monitor movement. If no motor movement is sensed, the DTC is set. The DSM retries motor operation on the next activation of the seat control switch. If no movement is detected after 250 milliseconds, the DSM disables the output. |
| B14CF:31 | Seat Recline Motor Output: No Signal | During self-test, the DSM attempts to operate the appropriate seat motor and uses the motor's position sensor to monitor movement. If no motor movement is sensed, the DTC is set. The DSM retries motor operation on the next activation of the seat control switch. If no movement is detected after 250 milliseconds, the DSM disables the output. |
| B14D0:31 | Seat Height Front/Tilt Motor Output: No Signal | During self-test, the DSM attempts to operate the appropriate seat track motor and uses the motor's position sensor to monitor movement. If no motor movement is sensed, the DTC is set. The DSM retries motor operation on the next activation of the seat control switch. If no movement is detected after 250 milliseconds, the DSM disables the output. |
| B14D2:31 | Seat Height Rear Motor Output: No Signal | During self-test, the DSM attempts to operate the appropriate seat track motor and uses the motor's position sensor to monitor movement. If no motor movement is sensed, the DTC is set. The DSM retries motor operation on the next activation of the seat control switch. If no movement is detected after 250 milliseconds, the DSM disables the output. |
| B1B89:11 | Seat Slide Motor Speed/Position Sensor: Circuit Short To Ground | If a short to ground condition is present on the affected motor's position sensor (Hall-effect) feedback circuit, the DTC is set. After a DTC is set, a memory recall is not possible but the seat control switch can operate the associated motor in two-second increments. |
| B1B89:12 | Seat Slide Motor Speed/Position Sensor: Circuit Short To Battery | If a short to voltage condition is present on the affected motor's position sensor (Hall-effect) feedback circuit, the DTC is set. After a DTC is set, a memory recall is not possible but the seat control switch can operate the associated motor in two-second increments. |
| B1B91:11 | Seat Tilt Motor Speed/Position Sensor: Circuit Short To Ground | If a short to ground condition is present on the affected motor's position sensor (Hall-effect) feedback circuit, the DTC is set. After a DTC is set, a memory recall is not possible but the seat control switch can operate the associated motor in two-second increments. |
| B1B91:12 | Seat Tilt Motor Speed/Position Sensor: Circuit Short To Battery | If a short to voltage condition is present on the affected motor's position sensor (Hall-effect) feedback circuit, the DTC is set. After a DTC is set, a memory recall is not possible but the seat control switch can operate the associated motor in two-second increments. |
| B1B93:11 | Seat Recline Motor Speed/Position Sensor: Circuit Short To Ground | If a short to ground condition is present on the affected motor's position sensor (Hall-effect) feedback circuit, the DTC is set. After a DTC is set, a memory recall is not possible but the seat control switch can operate the associated motor in two-second increments. |
| B1B93:12 | Seat Recline Motor Speed/Position Sensor: Circuit Short To Battery | If a short to voltage condition is present on the affected motor's position sensor (Hall-effect) feedback circuit, the DTC is set. After a DTC is set, a memory recall is not possible but the seat control switch can operate the associated motor in two-second increments. |
DDM DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B1C03:23 | Memory #1 Switch: Signal Stuck Low | If a short to ground is sensed on the switch input circuit during the DDM self-test, the DTC is set. If activity is sensed on the input circuit for greater than 2 minutes, the DTC is set as continuous. With the DTC set, any input signal on the circuit is ignored. |
| B1C04:23 | Memory #2 Switch: Signal Stuck Low | If a short to ground is sensed on the switch input circuit during the DDM self-test, the DTC is set. If activity is sensed on the input circuit for greater than 2 minutes, the DTC is set as continuous. With the DTC set, any input signal on the circuit is ignored. |
Possible Causes
- Wiring, terminals or connectors
- Memory SET switch
- Missing ignition status information
- Horizontal motor
- Seat track
- Seat backrest
