Inspection Procedure

1. Drive the vehicle and check if the function of the speedometer in the combination meter is normal.

   OK: 

   Actual vehicle speed and the speed indicated on the speedometer are the same. 

   HINT:

   The vehicle speed sensor is functioning normally when the indication on the speedometer is normal.

NG: GO TO  COMBINATION METER

2. Measure the resistance according to the value(s) in the table below.
   STANDARD RESISTANCE SPECIFIED CONDITION
   
   

   Tester connection	Condition	Specified condition
   SPD - E2-15	Ignition switch OFF	Below 1

NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: GO TO NEXT STEP 

1. Disconnect the multi-display connector E25 and combination meter connector E2.
2. Measure the resistance according to the value(s) in the table below.
   STANDARD RESISTANCE SPECIFIED CONDITION
   
   

   Tester connection	Condition	Specified condition
   SPD - Body ground	Ignition switch OFF	10 k or higher

   HINT:

   If the resistance between terminal SPD and body ground is less than 10 k, there may be a short in a wire harness, connector, or ECU.

NG: REPAIR OR REPLACE HARNESS OR CONNECTOR OR EACH ECU
