Why is the reverse light not working?
1 Answers
When reversing, the reverse light sends a reversing signal to people behind the vehicle. The main reasons for the reverse light not working are as follows: 1. The reverse light bulb is damaged and not functioning. 2. Faulty reverse gear switch in manual transmissions or faulty gear position switch in automatic transmissions. 3. The fuse in the reverse light circuit is blown. 4. Open circuit or poor contact in the reverse gear switch signal line. Self-inspection methods are as follows: 1. Test by honking the horn or turning on the signal light switch. If the horn sounds and the turn signal lights up, it indicates that the power line before the fuse is in good condition. Therefore, you can use a test light or the power short-circuit method to check for open circuits at the ammeter terminal, ignition switch terminal, light switch terminal, etc., in sequence. If the circuit connection is good, the light switch may be damaged. 2. If the horn does not sound when tested and the fuse has not tripped, it indicates an open circuit or poor connection somewhere in the power line before the fuse. If the fuse trips, it indicates a ground fault somewhere in the line after the fuse. You can disconnect the power lines of the horn and turn signal, then press the fuse button to test. If the fuse does not trip again and the lights turn on when the light switch is activated, it indicates a ground fault in the horn or turn signal circuit. If the fuse still trips, use the power short-circuit method to locate the ground fault in sequence. 3. If the test light shows good power at the light switch terminal, but when a certain position of the light switch is activated, the bimetal contacts frequently open and the light does not turn on, it indicates a ground fault somewhere in that light circuit. 4. While driving at night, if all the lights suddenly go out, stop the vehicle immediately and test the horn. If the horn sounds, it indicates that the power supply is still good, and you should still check the light circuit for ground faults or open circuits in sequence. If the horn does not sound, it may be due to the power line coming loose or breaking during driving. First, check the battery terminals for good connection, then proceed with the sequential inspection.
