This can be caused by a short to ground, which can be a frustrating issue to deal with. However, with the right tools and knowledge, you can fix this problem yourself and save money on costly repairs.
Step 1: Diagnose the Problem
Before you can fix the issue, you need to diagnose the problem. Start by checking the fuse for the heated backlite input circuit. If the fuse is blown, replace it and see if the error code disappears. If the fuse is not the issue, you will need to check the wiring for any damage or breaks. Use a multimeter to test the wiring for continuity and check for any shorts to ground.
Step 2: Repair the Wiring
If you find any damage or breaks in the wiring, you will need to repair it. Start by cutting out the damaged section of the wire and stripping the ends. Then, use a wire connector to join the two ends together. Make sure to use the appropriate size connector for the wire gauge. Once the wiring is repaired, test the circuit again to see if the error code has disappeared.
Step 3: Replace the Backlite
If the wiring is not the issue, the problem may be with the backlite itself. Check the backlite for any damage or cracks. If you find any damage, you will need to replace the backlite. This can be a difficult task, so it’s recommended that you seek the help of a professional if you’re not experienced with this type of repair.
Step 4: Clear the Error Code
Once you have fixed the issue, you will need to clear the error code. Use an OBD-II scanner to clear the code and reset the system. This will ensure that the error code does not reappear and that the system is functioning properly.
