NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to Next Step 

1. Clear the DTC (see DTC CHECK / CLEAR  ).
2. Turn the engine switch on (IG).
3. Check if the same DTC is recorded (see DTC CHECK / CLEAR  ).

   HINT:

   Reinstall the sensors, connectors, etc. and restore the vehicle to its prior condition before rechecking for DTCs.
