Exhaust Heat RECIRCULATION System Circuit [02/2014 - 11/2016]: Procedure
- CHECK HARNESS AND CONNECTOR (COMBINATION METER ASSEMBLY - TEMPERATURE SWITCH - BODY GROUND)
- Disconnect the F22 combination meter assembly connector.
- Disconnect the P2 temperature switch connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance (Check for Open)
Tester Connection Condition Specified Condition F22-5 (TWS2) - P2-2 (TWS2) Always Below 1 Ω P2-1 (GND) - Body ground Always Below 1 Ω Standard Resistance (Check for Short)
Tester Connection Condition Specified Condition F22-5 (TWS2) or P2-2 (TWS2) - Body ground Always 10 kΩ or higher Result
Result OK NG
Result:
NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
Result:
OK
Go to next step
- CHECK COMBINATION METER ASSEMBLY
- Turn the power switch on (IG).
- Disconnect the P2 temperature switch connector.
- Check the water temperature receiver gauge in the combination meter assembly.
Result
Result Proceed to Water temperature receiver gauge needle jumps from normal value to HI side A Water temperature receiver gauge needle jumps to HI side and stays there even after the connector is disconnected B Water temperature receiver gauge needle does not move from normal value even after the connector is disconnected C
Result:
A
END
Result:
C
