Taillight Relay Circuit

LIGHTING: LIGHTING SYSTEM: Taillight Relay Circuit
- Taillight Relay Circuit

DESCRIPTION

* The running light relay assembly receives the light control switch TAIL signal to control the taillight relay.

HINT
* If only one taillight does not illuminate, check the bulb or wire harness related to the bulb.
* The taillight relay is installed in the instrument panel junction block, so unlike conventional relays, it cannot be removed for inspection.
