Broken or chafed wiring (open/short to battery or ground) to the passenger mirror
Corroded or loose connector at the mirror or body control module (BCM)
Failed mirror adjustment motor
Faulty mirror position/drive module or body control module output
Blown fuse or fusible link supplying the mirror circuit
Water intrusion or contamination in the mirror assembly

Read and record all body module/mirror-related DTCs with a scan tool
Attempt to operate passenger mirror from driver and built-in mirror controls and note behavior
Inspect fuses related to mirror/BCM circuits
Visually inspect mirror assembly and harness for damage, corrosion, or water
Wiggle harness and connectors while operating mirror to check for intermittent faults
Check for technical service bulletins (TSBs) relevant to mirror circuits

Command voltage to mirror motor: approx. battery voltage (~12 V) when driven high, or switched to ground when driven low (varies by design)
Motor coil resistance: typically low ohms (depends on vehicle — expect a measurable low resistance rather than open circuit)
Control signals from BCM may be switched power or PWM — command should change when mirror switch is operated
Ground continuity expected between mirror ground pin and chassis ground

Verify the code with a scan tool and clear then re-check to confirm repeatability.
Operate the passenger mirror while observing behavior and listen for motor noise; note direction(s) that fail.
Inspect visible wiring and connectors at the mirror and door for corrosion, pin damage, or water entry; repair as needed.
Check related fuses and fusible links; replace if blown and inspect cause of failure.
Backprobe the mirror connector while commanding movement: verify presence of battery voltage or switched ground on the appropriate pins and that signals change when the switch is operated.
Measure motor resistance (with connector disconnected) to check for open or shorted windings; compare to known-good spec if available.
Check continuity to the body control module output and to chassis ground; repair any open/shorts found.
If wiring and connector are good and correct drive signals are present but motor does not respond, replace the passenger mirror assembly or motor.
If motor and mirror test good but there is no proper command from BCM, diagnose the BCM/mirror module output circuit (module replacement or reprogramming may be required per manufacturer procedures).
After repairs, clear codes and verify proper operation and that the DTC does not return.
