REFER to: Front Seats - System Operation and Component Description .
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B120A:01 | Passenger Seat Cushion Temperature Sensor: General Electrical Failure | If the passenger seat cushion blower motor temperature is outside the maximum temperature range, the SCME shuts down the passenger seat system and sets this DTC. |
| B120A:98 | Passenger Seat Cushion Temperature Sensor: Component or System Over Temperature | If the passenger seat cushion blower motor temperature is outside the maximum temperature range, the SCME shuts down the passenger seat system and sets this DTC. |
| B14BB:01 | Passenger Seat Cushion Thermal Electric Device: General Electrical Failure | If the outputs to the passenger seat cushion thermal electric device are shorted to ground or current flow is above a programmed threshold, the SCME shuts down the passenger seat system and sets this DTC. |
| B14BB:11 | Passenger Seat Cushion Thermal Electric Device: Circuit Short To Ground | If the outputs to the passenger seat cushion thermal electric device are shorted to ground or current flow is above a programmed threshold, the SCME shuts down the passenger seat system and sets this DTC. |
| B14BB:12 | Passenger Seat Cushion Thermal Electric Device: Circuit Short To Battery | If the outputs to the passenger seat cushion thermal electric device are shorted to voltage or current flow is below a programmed threshold, the SCME shuts down the passenger seat system and sets this DTC. |
| B14BB:13 | Passenger Seat Cushion Thermal Electric Device: Circuit Open | If the outputs to the passenger seat cushion thermal electric device are disconnected, open or current flow is below a programmed threshold, the SCME shuts down the passenger seat system and sets this DTC. |
| B14BB:1A | Passenger Seat Cushion Thermal Electric Device: Circuit Resistance Below Threshold | If the current flow of the outputs to the passenger seat cushion thermal electric device is above a programmed threshold, the SCME shuts down the passenger seat system and sets this DTC. |
| B14C0:11 | Passenger Seat Cushion Blower: Circuit Short To Ground | If the current to the passenger seat cushion blower exceeds a programmed threshold, the SCME shuts down the passenger seat system and sets this DTC. |
