DTC

Description

Fault Trigger Conditions

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.
