Rear End Door Window Defogger Switch
Inspection
S7RS0B9506012
1) Check rear end door window defogger switch for operation as follows.
a) Rear end door window defogger switch is built in HVAC control module (unit).
Remove HVAC control module (unit) referring to
“HVAC Control Unit Removal and Installation in
Section 7A” or “HVAC Control Module Removal
and Installation in Section 7B”.
b) Check that there is continuity between terminal (1) and terminal (2) of HVAC control module
(unit) when rear end door window defogger
switch is at ON position. (Rear end door window
defogger switch is kept in push.)
c) Check that there is no continuity between terminal (1) and terminal (2) of HVAC control
module (unit) when rear end door window
defogger switch is at OFF position.
If check result does not meet the above conditions,
replace HVAC control module (unit).
Rear End Door Window Defogger Relay
Inspection
S7RS0B9506013
1) Disconnect negative (–) cable from battery.
2) Remove junction block assembly for inspection of rear end door window defogger relay.
For removal, refer to “BCM (Included in Junction
Block Assembly) Removal a nd Installation in Section
10B”.
3) Remove rear end door window defogger relay (1) from junction block assembly (2).
4) Check that there is no continuity between terminal “c” and “d”. If there is continuity, replace relay.
5) Check that there is continuity between terminals “c” and “d” when a 12 V battery is connected to
terminals “a” and “b”.
If malfunction is found, replace it with a new one.

Inspection of BCM and its CircuitsS7RS0BA204018
BCM and its circuits can be checked at BCM wiring couplers by measuring voltage and resistance.
CAUTION!
BCM cannot be checked by itself. It is strictly prohibited to connect voltmeter or ohmmeter to BCM
with couplers disconnected from it.
Voltage Check1) Disconnect negative (–) cable at battery.
2) Remove BCM (included in junction block assembly) refe rring to “BCM (Included in Junction Block Assembly)
Removal and Installation”.
3) Connect connectors to BCM (1) and junction block assembly (2).
4) Check voltage at each terminal number of couplers connected. For connector and terminal number, refer to “Connector Layout Diagram of BCM and Junction Block Assembly”.
NOTE
• As each terminal voltage is affected by the battery voltage, confirm that it is 11 V or more when
ignition switch is ON.
• Voltage with asterisk (*) can not be measured by voltmeter because it is pulse signal. Check it with oscilloscope if necessary.
