CAUTION
!
HVAC control module can not be checked by itself.
It is strictly prohibited to connect voltmeter to HVAC control module with couplers disconnected from
it.
HVAC control module and its circuits can be checked at HVAC control module wiring couplers by measuring voltage.
Voltage Check
1) Remove HVAC control module. Refer to “HVAC Control Module Removal and Installation in Section 7A”.
2) Connect HVAC control module and body control module couplers to HVAC control module and body control
module.
3) Check each terminal voltage with couplers connected by referring to “HVAC Control Module Voltage Table: ”.
