NOTE: Also check intermediate connector A-03. If intermediate
connector A-03 is damaged, repair or replace the connector as
described in GROUP 00E, Harness Connector Inspection
.
Q: Is the wiring harness between condenser fan control
relay connector A-09X (terminal 1) and powertrain
control module D-132 (terminal 17) in good condition?
YES : Check that the air conditioning works normally.
NO : Repair the wiring harness. Check that the air
conditioning works normally.
STEP 14. Check the condenser fan motor.
When battery voltage is applied between the condenser fan
motor terminals, the motor should run.
Q: Is the check result normal?
YES : Go to Step 15.
NO : Replace the condenser fan motor.
STEP 15. Measure the resistance at condenser fan motor
connector A-26.
(1) Disconnect condenser fan motor connector A-26, and
measure the resistance at the wiring harness side.
(2) Measure the resistance value between terminal 2 and
ground.
• 2 ohms or less
Q: Does the measured resistance value correspond with
this range?
YES : No action to be taken.
NO : Go to Step 16.
