REAR AIR CONDITIONING DIAGNOSIS

TSB Revision

HEATER, AIR CONDITIONING AND VENTILATION

55A-54

DIAGNOSIS

STEP 1. Check the rear A/C switch (temperature control 
switch).

Connect the tester between the connector terminal number 3 
and number 5, between the terminal number 5 and number 13 
and make sure that the resistance value changes slowly within 
the standard value.

Standard value: 0 

 3 k

Q: Is the check result normal?

YES :  Go to Step 2.
NO :  Replace the rear air-conditioner switch.

STEP 2. Measure the resistance at rear A/C control unit 
connector E-20.

(1) Disconnect rear A/C control unit connector E-20, and 

measure at the wiring harness side.

(2) Turn the rear fan switch to the "ON" position.
(3) Turn the Rear fan control switch to the "OFF" position.

(4) Measure the resistance between terminal 13 and ground.

• The measured value should be 2 ohms or less.

Q: Does the measured resistance value correspond with 

this range?
YES : 
 Go to Step 5.
NO :   Go to Step 3.
