The door modules supply battery positive voltage and ground on opposing mirror motor control circuits based on the position of the mirror switch.
• | System voltage must be between 9.0 and 16.0 volts. |
• | The ignition switch must be in the ON position. |
• | If the mirror motor up/left control circuit is shorted to battery voltage and the mirror is commanded down or right. |
• | If the mirror motor up/left control circuit is shorted to ground and the mirror is commanded up or left. |
The outside rearview mirror will not operate properly on all axes.
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.
