Diagnostic procedure

STEP

INSPECTION

ACTION
1
INSPECT REFRIGERANT PRESSURE SENSOR CONNECTOR
• Turn the ignition switch to the off position.
• Disconnect the negative battery cable.
• Disconnect the refrigerant pressure sensor 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 5.
2
INSPECT REFRIGERANT PRESSURE SENSOR
• Inspect the refrigerant pressure sensor. (See REFRIGERANT PRESSURE SENSOR INSPECTION [FULL-AUTO AIR CONDITIONER].)
• Is it normal?
Yes
Go to the next step.
No
Replace the refrigerant pressure sensor.
(See REFRIGERANT PRESSURE SENSOR REMOVAL/INSTALLATION [FULL-AUTO AIR CONDITIONER].)
3
INSPECT REFRIGERANT PRESSURE SENSOR CIRCUIT FOR OPEN CIRCUIT
• Disconnect the climate control unit connector and the refrigerant pressure sensor connector.
• Is there continuity between the following terminals of the climate control unit and the refrigerant pressure sensor?
― 1C—C
― 1J—A
― 1N—B
Yes
Go to the next step.
No
Repair the wiring harness.
4
INSPECT REFRIGERANT PRESSURE SENSOR CIRCUIT FOR SHORT TO POWER SUPPLY
• Is there a short circuit to power supply in the wiring harness between the following terminals of the climate control unit terminal and refrigerant pressure sensor?
― 1J—A
Yes
Repair the wiring harness.
No
Go to the next step.
5
VERIFY CLIMATE CONTROL UNIT CONNECTOR CONDITION
• 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.
6
VERIFY THAT SAME DTC IS NOT OUTPUT AGAIN
• Reconnect the disconnected connectors.
• Clear the past malfunction from memory.
• Verify DTCs.
• Is DTC P0532 or P0533 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. (See CLIMATE CONTROL UNIT REMOVAL/INSTALLATION [FULL-AUTO AIR CONDITIONER].)
No
Go to the next step.
7
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.
