Q: Is the wiring harness between A/C compressor clutch relay connector
B-16X (terminal 2) and the ignition switch (IG2) in good condition?
YES:
It can be assumed that this malfunction is intermittent. Refer to
NOTE: Also check intermediate connector A-13, joint
connector C-04, junction block connectors C-214 and C-
215 for loose, corroded, or damaged terminals, or
terminals pushed back in the connector. If intermediate
connector A-13, joint connector C-04, junction block
connector C-214 or C-215 is damaged, repair or replace
the connector as described in HARNESS CONNECTOR

Q: Is the front blower relay continuity in good condition?
YES:
Go to Step 5.
NO:
Replace the front blower relay. The front blower motor should
operate normally.
STEP 5. Measure the voltage at front blower relay connector C-202.
1. Disconnect front blower relay connector C-202, and measure the voltage
at the junction block side.
2. Turn the i
gnition switch to the "ON"
position.

Q: Is the wiring harness between front blower relay connector C-202
(terminal 1) and the ignition switch (IG2) in good condition?
YES:
The front blower motor should operate normally.
NO:
Repair the wiring harness. The front blower motor should operate
normally.
STEP 7. Measure the voltage at front blower relay connector C-202.
1. Disconnect front blower relay connector C-202, and measure the voltage
at the junction block side.
NOTE: Also check junction block connector C-215 for loose,
corroded, or damaged terminals, or terminals pushed
back in the connector. If junction block connector C-215
is damaged, repair or replace the connector as
described in HARNESS CONNECTOR INSPECTION
.

Q: Is the wiring harness between front blower relay connector C-202
(terminal 5) and fusible link (1) in good condition?
YES:
The front blower motor should operate normally.
NO:
Repair the wiring harness. The front blower motor should operate
normally.
STEP 9. Check the wiring harness between A/C-ECU connector C-16
(terminal 9) and front blower relay connector C-202 (terminal 3).
NOTE: Also check junction block connector C-216 for loose,
corroded, or damaged terminals, or terminals pushed
back in the connector. If junction block connector C-216
is damaged, repair or replace the connector as
described in HARNESS CONNECTOR INSPECTION

Q: Is the wiring harness between A/C-ECU connector C-16 (terminal 9)
and front blower relay connector C-202 (terminal 3) in good condition?
YES:
Go to Step 10.
NO:
Repair the wiring harness. The front blower motor should operate
normally.
STEP 10. Check the wirin
g harness between front blower motor connector
C-111 (terminal 1) and front blower relay connector C-202 (terminal 4). NOTE: Also check junction block connector C-211 for loose,
corroded, or damaged terminals, or terminals pushed
back in the connector. If junction block connector C-211
is damaged, repair or replace the connector as
described in HARNESS CONNECTOR INSPECTION

Q: Is the wiring harness between front blower motor connector C-111
(terminal 1) and front blower relay connector C-202 (terminal 4) in good
condition?
YES:
The front blower motor should operate normally.
NO:
Repair the wiring harness. The front blower motor should operate
normally.
STEP 11. Check the front blower fan and motor operation.
When battery voltage is applied between the terminals, check that the motor
operates. Also, check that there is no abnormal noise.
Q: Is there any abnormal noise?
YES:
Go to Step 12.
NO:
Replace the front blower relay. The front blower motor should
o
perate normall
y.
NOTE: Also check junction block connector C-215 for loose,
corroded, or damaged terminals, or terminals pushed
back in the connector. If junction block connector C-215
is damaged, repair or replace the connector as
described in HARNESS CONNECTOR INSPECTION

.
2. Turn the ignition switch to the "ON" position.
3. Check if the DTC is set.
4. Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the check result satisfactory?
YES:
Go to Step 2.
NO:
Refer to
DIAGNOSTIC TROUBLE CODE CHART
.
STEP 2. Check the refrigerant level.
Use the refrigerant recovery station to remove all of the refrigerant, and then
calculate the amount of the refrigerant and charge it.
Q: Is the refrigerant level correct?
YES:
Replace the A/C-ECU.
NO:
Correct the refrigerant level (Refer to
REFRIGERANT LEAK
REPAIR PROCEDURE
). Check that the air conditioning works
normally.
