Taillight Control Relay
NOTE:
Taillight control relay may also be referred to as tail relay or taillight relay.
- Turn ignition off. Remove taillight control relay. Taillight control relay is located in driver side junction block. See Figure.
- Note identification of electrical terminals on taillight control relay. See Fig 1. Using an ohmmeter, check that no continuity exists between terminals No. 3 and 5 on taillight control relay. Check that continuity exists between terminals No. 1 and 2 on taillight control relay.
- Using jumper wires, apply battery voltage and ground to terminals No. 1 and 2 on taillight control relay. Check that continuity now exists between terminals No. 3 and 5 on taillight control relay. See Fig 1. If continuity is not as specified, replace taillight control relay if defective.
