What Does B2567 Mean?
B2567 indicates the Body Control Module (BCM) has detected a fault in the reverse mirror output circuit. This system controls the automatic tilting or adjustment of the side mirrors when the vehicle is shifted into reverse gear. The BCM has identified either an open circuit, short circuit, excessive resistance, or lack of expected feedback from the mirror tilt/adjustment motor during reverse gear operation.
Common Causes
35%
Faulty mirror actuator motor or internal circuit failure in the mirror assembly
30%
Damaged, corroded, or loose wiring harness connections between BCM and mirror assembly
20%
Water intrusion or corrosion inside mirror housing causing short or open circuit
10%
Failed Body Control Module output driver circuit
5%
Blown fuse or open circuit in mirror power supply circuit
Diagnostic Steps
1
Step 1: Visually inspect both side mirror assemblies for physical damage, water intrusion, or corrosion. Check mirror connector terminals for corrosion, bent pins, or moisture. Disconnect and reconnect mirror connectors to ensure proper seating.
2
Step 2: Using a digital multimeter, check for power and ground at the mirror connector with ignition on. Verify battery voltage on power supply pin and continuity to ground. Compare readings to factory wiring diagram specifications.
3
Step 3: With transmission in reverse and ignition on, command mirror tilt operation using scan tool bi-directional controls (if available). Monitor for mirror movement and listen for actuator motor operation. Check for voltage changes at mirror connector during commanded movement.
4
Step 4: Perform resistance test on mirror actuator motor by disconnecting mirror connector and measuring resistance across motor terminals. Typical values range from 20-200 ohms depending on manufacturer. Compare to known good mirror or service specifications.
5
Step 5: Inspect wiring harness from BCM to mirror assembly for chafing, pinching, or damage, particularly in door hinge area and door jamb where flexing occurs. Perform continuity and resistance tests on all mirror circuit wires from BCM connector to mirror connector.
6
Step 6: If all circuits test normal, substitute mirror assembly with known good unit or swap left/right mirrors to determine if fault follows component. Clear codes and test operation in reverse gear. If fault persists with different mirror, suspect BCM output driver failure.

The most common cause of B2567 (Reverse Mirror Output Circuit Failure) is: Faulty mirror actuator motor or internal circuit failure in the mirror assembly
Typical repair costs for B2567 range from $150 to $650, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle is safe to drive and operate normally. This code only affects the convenience feature of automatic mirror tilt when in reverse gear. Manual mirror adjustment should still function. Repair at convenience, no immediate safety concern.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to B2567 to identify the root cause.
