      A35-14 (S) - Body ground M (or S), "+" or "-" Ignition switch ON 11 to 14 V*
      Not in M (or S), "+" or "-" Ignition switch ON 0 to 1.5 V*
      TEXT IN ILLUSTRATION

      *a Front view of wire harness connector
      (to ECM)

      HINT: 

      *: The voltage will drop slightly due to the turning on of the back up light.

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK → See step   10 

  5. CHECK HARNESS AND CONNECTOR (BATTERY - PARK/NEUTRAL POSITION SWITCH)

      Tester Connection Switch Condition Specified Condition
      B14-1 (RB) - Body ground Ignition switch ON 11 to 14 V
      TEXT IN ILLUSTRATION

      *a Front view of wire harness connector
      (to Park/Neutral Position Switch)

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: Go to next step 

  6. INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY 
    1. Inspect the park/neutral position switch assembly. Refer to INSPECTION - Step 1 .

    NG → See step   11 

    OK: Go to next step
