Diagnostic Procedure
Step |
Inspection |
Action |
|
---|---|---|---|
1
|
VERIFY CLIMATE CONTROL UNIT CONNECTOR CONDITION
• Switch the ignition off.
• Disconnect the negative battery cable.
• Disconnect the climate control unit connectors.
• 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 malfunctioning vehicle wiring harness, connector, or terminal.
After repair procedure, go to the next step.
|
||
2
|
VERIFY CONNECTOR CONDITION
• Disconnect the following each sensor/actuator connectors.
• Inspect the connector and terminals (corrosion, damage, pin disconnection).
• Are the connector and terminals normal?
|
Yes
|
Go to the next step.
|
No
|
Replace the malfunctioning part.
After replace procedure, go to the next step.
|
||
3
|
INSPECT EACH SENSOR/ACTUATOR
• Inspect the following each sensor/actuator.
• Is it normal?
|
Yes
|
Go to the next step.
|
No
|
Replace the malfunctioning sensor/actuator.
After replace procedure, go to the next step.
|
||
4
|
INSPECT EACH SENSOR/ACTUATOR CIRCUIT FOR SHORT TO GROUND
• Inspect for continuity between the following terminal (wiring harness-side) and body ground:
• Is there continuity?
|
Yes
|
Refer to the wiring diagram and verify whether or not there is a common connector between climate control unit terminal 1N and each sensor/actuator terminals.
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.
Go to the next step.
|
No
|
Go to the next step.
|
||
5
|
VERIFY THAT SAME DTC IS NOT OUTPUT AGAIN
• Reconnect the disconnected connectors.
• Connect the negative battery cable.
• Clear the past malfunction from memory.
• Verify DTCs.
• Is DTC U200D:11 output?
|
Yes
|
Repeat the inspection from Step 1.
• If the malfunction does not recur, go to the next step.
• If the malfunction recurs, replace the climate control unit.
Go to the next step.
|
No
|
Go to the next step.
|
||
6
|
VERIFY THAT NO OTHER DTCs ARE PRESENT
• Verify other DTCs displayed.
• Are any other DTCs output?
|
Yes
|
Perform the corresponding DTC inspection.
|
No
|
DTC troubleshooting completed.
