Exhaust Heat RECIRCULATION System Circuit [11/2016 - ]: Procedure

1. Disconnect the F124 combination meter assembly connector.
2. Disconnect the P2 temperature switch connector.
3. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   F124-7 (TWS2) - P2-2 (TWS2)	Always	Below 1 Ω
   P2-1 (GND) - Body ground	Always	Below 1 Ω
   F124-7 (TWS2) or P2-2 (TWS2) - Body ground	Always	10 kΩ or higher

Result: 

NG 

REPAIR OR REPLACE HARNESS OR CONNECTOR 

Result: 

OK 

Go to next step 

1. Turn the power switch on (IG).
2. Disconnect the P2 temperature switch connector.
3. Check the water temperature receiver gauge in the combination meter assembly.

   Result	Proceed to
