Normal Operation and Fault Conditions
REFER to: Front Seats - System Operation and Component Description .
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B1209:01 | Driver Seat Back Temperature Sensor: General Electrical Failure | If the driver seat back blower motor temperature is outside the maximum temperature range, the SCME shuts down the driver seat system and sets this DTC. |
| B1209:98 | Driver Seat Back Temperature Sensor: Component or System Over Temperature | If the driver seat back blower motor temperature is outside the maximum temperature range, the SCME shuts down the driver seat system and sets this DTC. |
| B14BA:01 | Driver Seat Back Thermal Electric Device: General Electrical Failure | If the outputs to the driver seat back thermal electric device are shorted to ground or current flow is above a programmed threshold, the SCME shuts down the driver seat system and sets this DTC. |
| B14BA:11 | Driver Seat Back Thermal Electric Device: Circuit Short To Ground | If the outputs to the driver seat back thermal electric device are shorted to ground or current flow is above a programmed threshold, the SCME shuts down the driver seat system and sets this DTC. |
| B14BA:12 | Driver Seat Back Thermal Electric Device: Circuit Short To Battery | If the outputs to the driver seat back thermal electric device are shorted to voltage or current flow is below a programmed threshold, the SCME shuts down the driver seat system and sets this DTC. |
| B14BA:13 | Driver Seat Back Thermal Electric Device: Circuit Open | If the outputs to the driver seat back thermal electric device are disconnected, open or current flow is below a programmed threshold, the SCME shuts down the driver seat system and sets this DTC. |
| B14BA:1A | Driver Seat Back Thermal Electric Device: Circuit Resistance Below Threshold | If the current flow of the outputs to the driver seat back thermal electric device is above a programmed threshold, the SCME shuts down the driver seat system and sets this DTC. |
| B14BE:11 | Driver Seat Back Blower: Circuit Short To Ground | If the current to the driver seat back blower exceeds a programmed threshold, the SCME shuts down the driver seat system and sets this DTC. |
Possible Causes
- Wiring, terminals or connectors
