B1586

Diagnostic Chart:

Refer To Outside Mirrors: LH Power Mirror W/Memory (A45)
Refer To Outside Mirrors: RH Power Mirror W/Memory (A45)

CIRCUIT DESCRIPTION
The LH mirror and the RH mirror horizontal position sensors are potentiometers. The driver door module (DDM) and the passenger door module (PFDM) determine the horizontal position of the mirrors based on the signal voltage from these sensors.

ACTION TAKEN WHEN DTC SETS
Memory movements on this axis are disabled. Manual movements are not disabled.

CONDITIONS FOR CLEARING THE DTC
When the door modules no longer sense the failure.

CONDITIONS FOR RUNNING THE DTC
The door modules must be powered up and have battery voltage applied.

CONDITIONS FOR SETTING THE DTC
The code will be set when the mirror horizontal position sensor voltage is above or below the associated range limits (within 10%) for 30 Seconds in the requested position. The voltage failure range limits that the module uses to set the code will vary from vehicle to vehicle and from module to module. Therefore, use the table below to determine what the failed voltage range limits are for your particular vehicle/module.

DIAGNOSTIC AIDS

IMPORTANT: After readjusting the mirror positions, be sure to reset the mirror memory switch to the new positions.
^ If this code is set as a history code, but not as a current code, remove the fuse for the door module that set the code for 10 Seconds, then reinstall it.
^ A sticking switch may cause this DTC to set.
