Solutions
Suggest to repair at workshop as soon as possible.
1. Check if there is check light or error message in the meter cluster, identify the malfunction item.
2. Use the professional diagnose device to test the light bulb. If the bulb light up, it might be the reverse gear signal could not transmit over, causing the controller did not light up the bulb. Need to check the reverse gear signal wiring.
3. If the bulb is not light up, take it out and check if it is broken. If it is broken, use the multimeter to check the wiring to determine if there is any other problem in the wiring. Replace with new bulb with same power rating after confirming no error in the wiring.
