If you encounter the diagnostic code B1712, it indicates that the mirror switch right input has been shorted to ground. This issue can lead to malfunctioning mirror controls, affecting overall vehicle functionality. To address this, begin by inspecting the wiring and connectors linked to the mirror switch. Look for any visible damage or corrosion that could be causing the short.
Next, perform a multimeter test on the mirror switch circuit. Disconnect the switch and check for continuity between the connector pins and the ground. A continuous path suggests a short circuit, necessitating further inspection of the wiring harness for any frayed or damaged wires.
After isolating the problem, consider replacing the mirror switch if it shows signs of failure during testing. Ensure to clean and secure all connections before reconnecting the system. Clear the code using a diagnostic tool to confirm that the issue has been successfully resolved. Regularly checking the electrical components can prevent recurrence of these issues.
Understanding B1712 Error Code
The B1712 error code indicates a fault where the mirror switch R input is shorted to ground. This often triggers a malfunction within the vehicle’s electronic systems, specifically affecting the adjustment controls for exterior mirrors.
To diagnose this issue, follow these steps:
- Inspect the wiring and connectors associated with the mirror switch. Look for visible damage or corrosion that could cause a short circuit.
- Use a multimeter to test the resistance of the mirror switch input. A reading of zero ohms suggests a direct short to ground.
- Check the vehicle’s ground points for integrity. A poor ground connection can mistakenly signal a short.
If the wiring and connections appear intact, the mirror switch itself may be defective. In this case, replacing the switch will likely resolve the issue.
For preventive measures, keep an eye on any unusual behavior from the mirror control system. Early detection can save time and repair costs.
| Step | Description |
|---|---|
| 1 | Inspect wiring and connectors for damage. |
| 2 | Test mirror switch input using a multimeter. |
| 3 | Check ground points for proper connectivity. |
| 4 | Replace the mirror switch if necessary. |
Address the B1712 error promptly to maintain the functionality of your vehicle’s mirror controls and avoid further electrical issues. Regular maintenance can help detect such problems early.
Common Symptoms of Mirror Switch Malfunction
If you notice that your vehicle’s mirrors do not adjust, it is likely due to a malfunctioning mirror switch. Signs of an issue include the mirror not responding to adjustments, or the switch feeling stuck or unresponsive. You may also experience intermittent functionality, where the mirrors only adjust sporadically.
Another symptom is a clicking or buzzing noise when you attempt to operate the mirror switch. This noise might indicate an electrical short or a mechanical failure within the switch. If you detect any burning smells or notice melted components around the switch, this signals a serious problem that requires immediate attention to prevent further damage.
Check for any warning lights on your dashboard related to the mirrors; this could indicate an electrical issue affecting the mirror system. Lastly, if the mirrors adjust in the wrong direction or only partially, this misalignment points to a faulty switch or connection issue.
For best practice, inspect the mirror switch and its connections regularly if you experience these symptoms. Conduct a visual check to ensure there are no visible signs of wear or damage. If issues persist, replacing the mirror switch is advisable to restore proper functionality and enhance driving safety.
Diagnosis Steps for B1712 Code
Begin your diagnosis by checking for visible damage in the wiring and connectors related to the mirror switch. Look specifically for frayed wires or corrosion which could signal a short circuit.
Next, utilize a multimeter to measure the resistance in the mirror switch circuit. Follow these steps:
- Disconnect the mirror switch from the vehicle harness.
- Set the multimeter to the resistance (ohms) setting.
- Measure the resistance between the mirror switch terminals.
A reading of zero indicates a short to ground, confirming the B1712 code. If resistance is within the manufacturer’s specifications, move to the next step.
Inspect the vehicle’s ground connections. Ensure that all ground points for the mirror switch circuit are clean and free of corrosion. Tighten any loose connections.
Check the vehicle’s body control module (BCM) for fault codes or malfunction indicators. A scan tool may reveal additional codes that could relate to the B1712, guiding further investigation.
If all components test well, examine the mirror switch itself:
- Reconnect the mirror switch.
- Activate the switch and monitor its behavior.
- Assess if moving the switch causes any changes in the reading on your multimeter.
If the switch still shows signs of a short or malfunctions, consider replacing it with a new component. After replacement, clear any fault codes from the BCM and retest the system.
Complete your diagnosis by reviewing the entire circuit for continuity. Use the wiring diagram to trace connections and verify that there are no additional shorts that may exist outside of the mirror switch.
Tools Required for Troubleshooting
To effectively troubleshoot the B1712 – Mirror Switch R Input shorted to ground issue, gather the following tools before you begin:
Multimeter
A multimeter is indispensable for measuring voltage, current, and resistance. Use it to check for short circuits and to test the continuity of wires leading to the mirror switch. Set the multimeter to the ohm setting to identify any unexpected resistance levels that indicate a short to ground.
Wire Strippers and Crimpers
Keep wire strippers and crimpers handy to repair any damaged wires. If you discover frayed or corroded wires, strip back the insulation and crimp on a new connector to ensure a reliable connection.
A wiring diagram for the vehicle can also be highly beneficial. It helps in pinpointing the exact connections involved in the mirror switch circuitry, allowing for a systematic approach to identifying issues.
Finally, a flashlight or work light will aid in illuminating tight spaces, ensuring you can see all components clearly while working. With these tools at your disposal, you’ll be well-equipped to tackle the shorted input issue efficiently.
Visual Inspection of the Mirror Switch Circuit
Begin with a clear visual examination of the mirror switch circuit to identify any obvious issues. Look for signs of physical damage, such as burnt spots or broken components.
Key Areas to Inspect
- Connector Pins: Check for corrosion, bent pins, or loose connections. Secure all connections to avoid intermittent faults.
- Wiring: Inspect the wiring harness for fraying, cuts, or signs of wear. Ensure all wires are properly insulated and securely attached.
- Switch Mechanism: Observe the mirror switch itself for any signs of sticking or malfunctioning. Test its operation manually to confirm movement is smooth.
- Ground Connections: Confirm that ground points in the circuit are clean and securely fastened. A poor ground can lead to short circuits.
Common Fault Indicators

Utilizing a flashlight can assist in spot-checking hard-to-reach areas. Maintain safety by disconnecting power before beginning the inspection. Address any findings immediately to prevent further complications.
Checking for Ground Short in Wiring Harness
Inspect the wiring harness for any signs of damage or wear. Look for frayed insulation, pinched wires, or exposed conductors. Focus on areas where the harness may flex or rub against metal components.
Utilize a multimeter to check for continuity between the ground wires and the vehicle chassis. Disconnect the battery to prevent accidental shorts during testing. Set the multimeter to continuity mode, connecting one probe to a ground point on the chassis and the other probe to each ground wire in the harness. A continuous beep indicates a short to ground.
Identifying the Short
Trace the wiring harness along its entire length, paying close attention to connectors and junctions. In some cases, connectors may have internal faults causing a ground short. Check these thoroughly by disconnecting each connector and retesting for continuity. If the short disappears upon disconnection, inspect the connector for corrosion or damage.
Repair Procedures
Should a ground short be found, secure the affected areas by soldering new wire sections or using heat-shrink tubing. Ensure all connections are properly insulated to prevent future shorts. Reorganize wiring to avoid contact with sharp edges or moving parts that may lead to wear over time.
| Action | Description |
|---|---|
| Visual Inspection | Check for physical damage to the wiring harness. |
