Diagnostic Procedure

STEP

INSPECTION

ACTION
1
INSPECT AMBIENT TEMPERATURE SENSOR CONNECTOR AND TERMINALS
•  Switch the ignition to off.
•  Disconnect the negative battery cable.
•  Disconnect the ambient temperature sensor connector.
•  Inspect the connector and terminals (corrosion, damage, pin disconnection).
•  Is there any malfunction?
Yes
Repair or replace the connector or terminals, then go to Step 6.
No
Go to the next step.
2
INSPECT AMBIENT TEMPERATURE SENSOR
•  Inspect the ambient temperature sensor.
•  Is there any malfunction?
Yes
Replace the ambient temperature sensor, then go to Step 6.
(See AMBIENT TEMPERATURE SENSOR REMOVAL/INSTALLATION [MANUAL AIR CONDITIONER].)
(See AMBIENT TEMPERATURE SENSOR REMOVAL/INSTALLATION [FULL-AUTO AIR CONDITIONER].)
No
Go to the next step.
3
INSPECT INSTRUMENT CLUSTER CONNECTOR AND TERMINALS
•  Disconnect the instrument cluster connector.
•  Inspect the connector and terminals (corrosion, damage, pin disconnection).
•  Is there any malfunction?
Yes
Repair or replace the connector or terminals, then go to Step 6.
No
Go to the next step.
4
INSPECT AMBIENT TEMPERATURE SENSOR CIRCUIT FOR SHORT TO GROUND
•  Ambient temperature sensor and instrument cluster connectors are disconnected.
•  Inspect for continuity between ambient temperature sensor terminal B (wiring harness-side) and body ground.
•  Is there continuity?
Yes
Repair or replace the wiring harness for a possible short to ground, then go to Step 6.
No
Go to the next step.
5
INSPECT AMBIENT TEMPERATURE SENSOR CIRCUIT FOR OPEN CIRCUIT
•  Ambient temperature sensor and instrument cluster connectors are disconnected.
•  Inspect for continuity between the following terminals (wiring harness-side):
―  Ambient temperature sensor terminal B—Instrument cluster terminal 1B
―  Ambient temperature sensor terminal A—Instrument cluster terminal 1C
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for a possible open circuit, then go to the next step.
6
VERIFY TROUBLESHOOTING COMPLETED
•  Make sure to reconnect all disconnected connectors.
•  Reconnect the negative battery cable.
•  Clear the DTC from the instrument cluster using the M-MDS.
•  Verify the instrument cluster DTC using the M-MDS.
•  Is the same DTC present?
Yes
Replace the instrument cluster, then go to the next step.
(See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
No
Go to the next step.
7
VERIFY THAT NO OTHER DTCs ARE PRESENT
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [INSTRUMENT CLUSTER].)
No
DTC troubleshooting completed.
