7 Wire harness check
1) Connect connector to HVAC control module with ignition
switch turned OFF.
2) Measure voltage between “GRY/RED” wire terminal of
temperature control actuator connector and vehicle body
ground with ignition switch turned ON when temperature
selector is operation to HOT direction.
Is voltage 10 – 14 V?
Go to Step 11. Go to Step 8.
8 Wire harness check
1) Disconnect connector from HVAC control module with
ignition switch turned OFF.
2) Check for proper connection to HVAC control module
connector at “G51-3” and “G51-4” terminals.
3) If OK, measure resistance between “GRY/RED” wire
terminal of temperature control actuator connector and
“G51-4” terminal of HVAC control module connector.
Is resistance below 5
Ω ?
Go to Step 9. “GRY/RED” wire open
or high resistance
circuit.
