INSPECT PCM DTC (INSPECT GENERATOR CIRCUIT)
• Switch the ignition off.
• Connect the M-MDS to the DLC-2.
• Perform the PCM DTC inspection using the M-MDS.
• Are any DTCs displayed?
|
Yes
|
Go to the applicable DTC inspection.
|
|
No
|
Go to the next step.
|

|
INSPECT FUSE
• Switch the ignition off.
• Disconnect the negative battery terminal.
• Remove the METER2 15 A, ROOM 25 A, and INTERIOR 10 A fuses.
• Are the fuses normal?
|
Yes
|
Install the METER2 15 A, ROOM 25 A, and INTERIOR 10 A fuses, then go to the next step.
|
|
No
|
If the METER2 15 A fuse is blown:
• Refer to the wiring diagram and verify whether or not there is a common connector between METER2 15 A fuse and front climate control unit / rear climate control unit terminal.
If there is a common connector:
-
? Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground.
? Repair or replace the malfunctioning part.
If there is no common connector:
-
? Repair or replace the wiring harness which has a short to ground.
• Replace the fuse.
If the ROOM 25 A or INTERIOR 10 A fuse is blown:
• Refer to the wiring diagram and verify whether or not there is a common connector between ROOM 25 A fuse and front climate control unit / rear climate control unit terminal.
If there is a common connector:
-
? Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground.
? Repair or replace the malfunctioning part.
If there is no common connector:
-
? Repair or replace the wiring harness which has a short to ground.
• Replace the fuse.
If the fuse is damaged:
• Replace the fuse.
Then go to Step 7.

INSPECT IGNITION RELAY (IG1_STAB) FOR MALFUNCTION
• Remove the IGNITION relay (IG1_STAB).
• Inspect the IGNITION relay (IG1_STAB).
• Is the IGNITION relay (IG1_STAB) normal?
|
Yes
|
Go to the next step.
|
|
No
|
Replace the IGNITION relay (IG1_STAB).
Then go to Step 7.

|
Yes
|
Go to the next step.
|
|
No
|
Replace or charge the battery.
Then go to Step 7.
|
|
5
|
VERIFY FRONT AND REAR CLIMATE CONTROL UNIT CONNECTOR CONDITION
• Disconnect the front and rear climate control unit connector.
• Inspect the connector and terminals (corrosion, damage, pin disconnection).
• Are the connector and terminals normal?
|
Yes
|
Go to the next step.
|
|
No
|
Repair/replace the connector or terminal.
After repair procedure, go to Step 7.
|
|
6
|
INSPECT FRONT AND REAR CLIMATE CONTROL UNIT POWER SUPPLY CIRCUIT FOR OPEN CIRCUIT
• Inspect for continuity between the following terminals (wiring harness-side) and battery positive terminal.
-
? Front climate control unit terminal 1W
? Front climate control unit terminal 1U
? Rear climate control unit terminal X
? Rear climate control unit terminal V
• Is there continuity?
|
Yes
|
Go to the next step.
|
|
No
|
Refer to the wiring diagram and verify whether or not there is a common connector between front / rear climate control unit terminal and battery positive terminal.
If there is a common connector:
• Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit.
• Repair or replace the malfunctioning part.
If there is no common connector:
• Repair or replace the wiring harness which has an open circuit.
Go to the next step.
|

7
|
INSPECT CLIMATE CONTROL UNIT
• Reconnect the disconnected connectors.
• Connect the negative battery terminal.
• Clear the DTC from the climate control unit memory using the M-MDS.
• Perform the DTC inspection for the climate control unit using the M-MDS.
• Is the same DTC displayed?
|
Yes
|
Repeat the inspection from Step 1.
• If DTC U3003:16 or U3003:17 is displayed, replace the front climate control unit.
• If DTC U3006:16 or U3006:17 is displayed, replace the rear climate control unit.
Go to the next step.
|
|
No
|
Go to the next step.
|
|
8
|
VERIFY THAT NO OTHER DTCs ARE PRESENT
• Verify other DTCs displayed.
• Are any other DTCs displayed?
|
