Circuit Description
The driver door module supplies battery positive voltage to the power mirror switch. When the mirror direction switch is placed in the up or down position, the appropriate signal circuit is switched to battery voltage. The driver door module senses the voltage change and activates the selected outside rearview mirror in the appropriate direction.
Conditions for Running the DTC
| • | Battery voltage must be between 9.0-16.0 volts. |
| • | The ignition switch is in the ON position. |
Conditions for Setting the DTC
The driver door module senses an active state on both the mirror switch up and down signal circuits greater than 3 seconds.
Action Taken When the DTC Sets
The driver door module will ignore the continuous inputs from the switch. The driver door module will respond to all other valid switch inputs.
Conditions for Clearing the DTC
When the fault is no longer present, the door module changes the current DTC to a history DTC. The door module will clear the history DTC after 50 fault free ignition cycles, or in response to a scan tool command.
