DTC Fault Trigger Conditions
DTC | Description | Fault Trigger Conditions |
|---|---|---|
B1086:11 | Air Distribution Damper Motor: Circuit Short to Ground | This DTC sets when the module senses lower than expected voltage on an actuator motor circuit when voltage is applied to drive the motor, indicating a short to ground. The motor can move only in one direction. |
B1086:12 Air Distribution Damper Motor: Circuit Short to Battery | This DTC sets when the module senses higher than expected voltage on the actuator motor circuit when ground is applied to drive the motor, indicating a short to voltage. The motor can move only in one direction. | |
B1086:13 Air Distribution Damper Motor: Circuit Open | This DTC sets when the module senses no voltage on the actuator motor circuit when ground is applied to drive the motor, indicating an open circuit. The motor cannot move. | |
B11E7:12 Air Distribution Damper Position Sensor: Circuit Short to Battery | This DTC sets when the module senses greater than 5 volts on the actuator feedback circuit, indicating a short to voltage. | |
B11E7:14 Air Distribution Damper Position Sensor: Circuit Short to Ground or Open | This DTC sets when the module senses less than 1 volt on the actuator feedback circuit, indicating an open circuit or a short to ground. |
