CIRCUIT OPERATION
At the same time that the turn-signal lamps are illu-
minated, the ETACS-ECU sends a signal to illumi-
nate the turn-signal lamp indicator via the CAN bus
line.
.
TECHNICAL DESCRIPTION (COMMENT)
If the turn-signal indicator does not illuminate nor-
mally, connector(s), wiring harness in the CAN bus
lines, the ETACS-ECU or the combination meter may
be defective.
.
TROUBLESHOOTING HINTS

Refer to configuration diagrams GROUP-80
The wiring harness or connectors may have
loose, corroded, or damaged terminals, or termi-
nals pushed back in the connector
The combination meter may be defective
