Inspection Procedure

HINT:

If the vehicle is in key cancel mode, change to normal mode (see CUSTOMIZE PARAMETERS ).

1. CHECK WHETHER DTC OUTPUT RECURS 
   1. Clear the DTCs (see DTC CHECK / CLEAR  ).

      HINT:

      After all DTCs are cleared, check if the trouble occurs again 5 seconds after the engine switch is turned on (IG).

   2. Check for DTCs again.

      OK: No DTC is output. 

   NG: GO TO DTC CHART (See  DIAGNOSTIC TROUBLE CODE CHART   ) 

   OK: GO TO NEXT STEP 

2. CHECK ENGINE SWITCH (SWITCH CONDITION) 
   1. Ensure the key is inside the cabin.
   2. Check that the engine switch indicator illuminates in green when the shift lever is in P or N and the brake pedal is depressed.

      OK: Engine switch indicator illuminates in green. 

   NG: GO TO ROOM OSCILLATOR DOES NOT RECOGNIZE KEY  (See ROOM OSCILLATOR DOES NOT RECOGNIZE KEY )

   OK: GO TO NEXT STEP 

3. READ VALUE OF INTELLIGENT TESTER OR TECHSTREAM (RELAY MONITOR)
