DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B1663 | Seat Driver Front Up/Down Motor Stalled | 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 will retry motor operation on the next activation of the seat control switch. If no movement continues to be monitored after 250 milliseconds, the DSM disables the output. |
| B1664 | Seat Driver Rear Up/Down Motor Stalled | 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 will retry motor operation on the next activation of the seat control switch. If no movement continues to be monitored after 250 milliseconds, the DSM disables the output. |
| B1665 | Seat Driver Forward/Backward Motor Stalled | 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 will retry motor operation on the next activation of the seat control switch. If no movement continues to be monitored after 250 milliseconds, the DSM disables the output. |
| B1666 | Seat Driver Recline Motor Stalled | During self-test, the DSM attempts to operate the recliner motor and uses the recliner motor position sensor to monitor movement. If no motor movement is sensed, the DTC is set. The DSM will retry motor operation on the next activation of the seat control switch. If no motor movement is still monitored after 250 milliseconds, the DSM disables the output. |
| B1703 | Seat Driver Recline Forward Switch Circuit Short to Battery | If voltage is sensed on the switch input circuit during the DSM Self-Test, the DTC is set. If voltage 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. |
| B1707 | Seat Driver Recline Rearward Switch Circuit Short to Battery | If voltage is sensed on the switch input circuit during the DSM Self-Test, the DTC is set. If voltage 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. |
| B1711 | Seat Driver Front Up Switch Circuit Short to Battery | If voltage is sensed on the switch input circuit during the DSM Self-Test, the DTC is set. If voltage 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. |
| B1715 | Seat Driver Front Down Switch Circuit Short to Battery | If voltage is sensed on the switch input circuit during the DSM Self-Test, the DTC is set. If voltage 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. |
| B1719 | Seat Driver Forward Switch Circuit Short to Battery | If voltage is sensed on the switch input circuit during the DSM Self-Test, the DTC is set. If voltage 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. |
| B1723 | Seat Driver Rearward Switch Circuit Short to Battery | If voltage is sensed on the switch input circuit during the DSM Self-Test, the DTC is set. If voltage 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. |
| B1727 | Seat Driver Rear Up Switch Circuit Short to Battery | If voltage is sensed on the switch input circuit during the DSM Self-Test, the DTC is set. If voltage 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. |
| B1731 | Seat Driver Rear Down Switch Circuit Short to Battery | If voltage is sensed on the switch input circuit during the DSM Self-Test, the DTC is set. If voltage 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
