Common Troubleshooting Steps
When dealing with OBD-II code B1668, which indicates a “Mirror Driver Right/Left Motor Stalled,” it typically relates to issues with the power mirror system in a vehicle. Here are some common troubleshooting steps to help diagnose and potentially resolve the issue:
- Visual Inspection: **Check the Mirrors: Inspect the mirrors for any physical damage or obstructions that may prevent movement.
- **Wiring and Connectors: Look for damaged wires, loose connections, or corrosion in the wiring harness leading to the mirror motors.
- Check the Power Supply: **Fuses: Check the fuse related to the power mirrors. A blown fuse can prevent the motors from receiving power.
- **Voltage Test: Use a multimeter to check for voltage at the mirror connector when the mirror adjustment switch is activated.
- Test the Mirror Switch: **Functionality: Ensure that the mirror adjustment switch is functioning properly. A faulty switch can prevent the motors from receiving the signal to move.
- **Bypass Test: If possible, bypass the switch to directly apply power to the mirror motors to see if they respond.
- Motor Functionality: **Direct Power Test: If the wiring and switch are good, apply direct power to the mirror motor to see if it operates. If it does not move, the motor may be faulty and need replacement.
- **Resistance Check: Measure the resistance of the motor. If it shows an open circuit or very low resistance, the motor may be defective.
- Check for Obstructions: **Physical Blockage: Ensure there are no obstructions preventing the mirror from moving. Sometimes debris or ice can cause the motor to stall.
- Scan for Additional Codes: **Check for Other Codes: Use an OBD-II scanner to check for any additional trouble codes that may provide more context or indicate related issues.
- Reset the System: **Clear Codes: After performing repairs or adjustments, clear the trouble codes and see if the code returns after testing the mirrors again.
- Consult the Service Manual: **Specific Procedures: Refer to the vehicle’s service manual for specific troubleshooting procedures and specifications related to the mirror system.
- Professional Help: **Seek Assistance: If the issue persists after performing these steps, consider consulting a professional mechanic or an automotive electrician for further diagnosis. By following these steps, you should be able to identify the cause of the B1668 code and take appropriate action to resolve the issue.
