GENERAL INFORMATION

Some electrical components in the vehicle use relays to transmit an electrical signal to a circuit component. If a relay fails, the electrical component it controls will also not function properly.
Various relays are installed in different locations in the vehicle.
If you suspect that a relay is faulty, it can be removed and taken to a repair shop for testing. Faulty relays must be replaced.
