CIRCUIT OPERATION
The ETACS-ECU operates the headlight automatic
shutdown function according to the following signals:
• Ignition switch (IG1)
• Driver's door switch
• Taillight switch
• Headlight switch
.
TECHNICAL DESCRIPTION (COMMENT)
If the function does not work normally, the input cir-
cuit system from the switches, the ETACS-ECU or
the front-ECU may be defective (refer to "CIRCUIT
OPERATION").
.
TROUBLESHOOTING HINTS
• The driver's door switch may be defective
• The column switch (lighting and turn-signal
switch) may be defective
• The ETACS-ECU may be defective
• The front-ECU may be defective
• The wiring harness or connectors may have
loose, corroded, or damaged terminals, or termi-
nals pushed back in the connector
