Common Troubleshooting Steps

The OBD-II code B1667 indicates a problem with the mirror driver motor, specifically that the up/down motor is stalled. This can occur in vehicles equipped with power mirrors. Here are some common troubleshooting steps to diagnose and potentially resolve the issue:

• Visual Inspection:
• Check the mirror assembly for any physical damage or obstructions that may prevent the mirror from moving.
• Inspect the wiring harness and connectors for signs of damage, corrosion, or loose connections.
• Check the Power Supply:
• Use a multimeter to check for voltage at the mirror motor connector when the mirror control switch is activated. Ensure that the correct voltage is present.
• If there is no voltage, trace the wiring back to the switch and check for continuity and any breaks in the wiring.
• Test the Mirror Switch:
• The mirror control switch itself may be faulty. Test the switch for proper operation using a multimeter. If the switch is not functioning correctly, it may need to be replaced.
• Inspect the Mirror Motor:
• If the switch is functioning, the issue may lie with the mirror motor itself. Disconnect the motor and test it directly with a power source to see if it operates. If it does not move, the motor may be faulty and require replacement.
• Check for Obstructions:
• Ensure that there are no physical obstructions preventing the mirror from moving. Sometimes debris or ice can block the movement.
• Clear the Code:
• After performing the above checks and repairs, clear the OBD-II code using a scan tool and test the mirror operation again. Monitor for any reoccurrence of the code.
• Consult the Service Manual:
• Refer to the vehicle’s service manual for specific wiring diagrams and troubleshooting procedures related to the mirror system.
• Professional Diagnosis:
• If the issue persists after performing these steps, it may be best to consult a professional mechanic or technician who can perform more advanced diagnostics. By following these steps, you should be able to identify the cause of the B1667 code and take appropriate action to resolve the issue.
