DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B1151:4B | Passenger Seat Cushion: Over Temperature | Sets when the SCME senses the right front cushion temperature has exceeded 110 deg.C (230 deg.F) for more than 4 seconds. When this DTC sets, the SCME disables the circuit until the ignition is cycled. |
| B1155:01 | Passenger Seat: General Electrical Failure | Sets when the SCME senses the right front heater element current draw has exceeded a specified threshold. When this DTC sets, the SCME disables the circuit until the ignition is cycled. |
| B1155:11 | Passenger Seat: Circuit Short To Ground | Sets when the SCME senses the right front heater element current draw has exceeded a specified threshold. When this DTC sets, the SCME disables the circuit until the ignition is cycled. |
| B1155:12 | Passenger Seat: Circuit Short To Battery | Sets when the SCME senses the right front heater circuit voltage is above a specified threshold when the driver is active. When this DTC sets, the SCME disables the circuit until the ignition is cycled. |
| B1155:13 | Passenger Seat: Circuit Open | Sets when the SCME senses the right front heater element current draw is less than a specified threshold. When this DTC sets, the SCME disables the circuit until the ignition is cycled. |
| B1155:1A | Passenger Seat: Circuit Resistance Below Threshold | Sets when the SCME senses the right front heater element current draw is more than a specified threshold. When this DTC sets, the SCME disables the circuit until the ignition is cycled. |
| B120A:01 | Passenger Seat Cushion Temperature Sensor: General Electrical Failure | Sets when the SCME senses the right front heater sensor voltage is out-of-range low or high. When this DTC sets, the SCME disables the circuit until the ignition is cycled. |
| B120A:11 | Passenger Seat Cushion Temperature Sensor: Circuit Short To Ground | Sets when the SCME senses the right front heater sensor voltage is out-of-range low. When this DTC sets, the SCME disables the circuit until the ignition is cycled. |
| B120A:15 | Passenger Seat Cushion Temperature Sensor: Circuit Short To Battery or Open | Sets when the SCME senses the right front heater sensor voltage is out-of-range high. When this DTC sets, the SCME disables the circuit until the ignition is cycled. |
Possible Causes
- Wiring, terminals or connectors
