CIRCUIT OPERATION
When the lighting switch is set to "TAIL" position, the 
"TAIL" signal is sent through the column-ECU (incor-
porated in the column switch) to the front-ECU. If the 
front-ECU receives the "TAIL" signal through the col-
umn-ECU, the front-ECU turns on the taillight relay 
(incorporated in the front-ECU), thus causing the tail-
lights to illuminate.

.

TECHNICAL DESCRIPTION (COMMENT)
If the taillights do not illuminate normally, the column 
switch or the front-ECU may be defective.

.

TROUBLESHOOTING HINTS

• The column switch (taillight switch) may be defec-

tive

• The front-ECU may be defective
