DESCRIPTION	Windshield wiper mode switch circuit malfunction
DETECTION CONDITION	• Short to ground in the windshield wiper mode switch circuit with the windshield wiper mode switch off.
POSSIBLE CAUSE	• Wiper and washer switch connector or terminals malfunction • Auto light/wiper control module connector or terminals malfunction • Short to ground in wiring harness between the following terminals: ― Wiper and washer switch terminal G—Auto light/wiper control module terminal V • BCM connector or terminals malfunction • Short to ground in wiring harness between the following terminals: ― Wiper and washer switch terminal I—BCM terminal 4J or auto light/wiper control module terminal K ― Wiper and washer switch terminal E—BCM terminal 4M or auto light/wiper control module terminal M ― Auto light/wiper control module terminal P—BCM terminal 4I • Windshield wiper and washer switch malfunction • Auto light/wiper control module malfunction • BCM malfunction

Diagnostic Procedure

STEP	INSPECTION		ACTION
1	CONFIRM BCM DTC • Clear the DTC using the M-MDS. (See CLEARING DTC [BCM].) • Perform the BCM DTC inspection using the M-MDS with the windshield wiper mode switch off. (See DTC INSPECTION [BCM].) • Is the same DTC present?	Yes	Go to the next step.
1		No	Go to Step 10.
2	INSPECT WIPER AND WASHER SWITCH CONNECTOR AND TERMINALS • Switch the ignition to off. • Disconnect the negative battery cable. • Disconnect the wiper and washer switch connector. • Inspect the connector and terminals (corrosion, damage, pin disconnection). • Is there any malfunction?	Yes	Repair or replace the connector or terminals, then go to Step 9.
2		No	Go to the next step.
3	INSPECT AUTO LIGHT/WIPER CONTROL MODULE CONNECTOR AND TERMINALS • Disconnect the auto light/wiper control module connector. • Inspect the connector and terminals (corrosion, damage, pin disconnection). • Is there any malfunction?
