Eclipse V6-3.0L SOHC (2003)
Taillight Relay Circuit
CIRCUIT OPERATION
When the lighting switch is set to "TAIL" position, the "TAIL" signal is sent through the column-ECU (incorporated in the column switch) to the
front-ECU. IF the front-ECU receives the "TAIL" signal through the column-ECU, the front-ECU turns on the tail light relay (incorporated in the
front-ECU), thus causing the tail lights to illuminate.
TECHNICAL DESCRIPTION (COMMENT)
If the tail lights do not illuminate normally, the column switch or the front-ECU may be defective.
