Check Rear Window Defogger Switch Circuit BIS00108
1. CHECK REAR WINDOW DEFOGGER SWITCH OPERATION
With CONSULT-II
Check “REAR DEF SW ” in DATA MONITOR mode with CONSULT-II.
Without CONSULT-II
1. Turn ignition switch ON.
2. Check voltage between BCM connector and ground.
OK or NG
OK >> Rear window defogger switch circuit is OK.
NG >> GO TO 2. (with navi or display unit)
>> GO TO 4. (except with navi or display unit)
2. CHECK HARNESS CONTINUITY
1. Turn ignition switch OFF.
2. Disconnect BCM and A/C and AV switch connector.
3. Check continuity between BCM connector M3 terminal 9 and A/
C and AV switch connector M40 terminal 9.
4. Check continuity between BCM connector M3 terminal 9 and
ground.
OK or NG
OK >> GO TO 3.
NG >> Repair or replace harness.When rear window defogger switch is turned to ON

Example: Data link connector branch line open circuit
NOTE:
When data link connector branch line is open, transmission and reception of CAN communication signals
is not affected. Therefore, no symptoms occur. However, be sure to repair malfunctioning circuit.
When data link connector branch line is open, the screen-display of the CONSULT-II “SELECT SYSTEM”
screen may be the same as when the CAN communication line has short-circuit. However, symptoms dif-
fer depending on the case. See below chart for the differences.
