HINT:

Start the inspection from step 1 when using the hand-held tester, and start from step 2 when not using the hand-held tester.

1. 1 READ VALUE OF HAND-HELD TESTER 
   1. Connect the hand-held tester to the DLC3.
   2. Turn the ignition switch to the ON position and press the hand-held tester main switch on.
   3. Select the item below in the DATA LIST, and read the displays on the hand-held tester.

   ALL: 

   HAND-HELD TESTER VALUE
   
   

   Hand-held Tester Display	Measurement Item/Range (Display)	Normal Condition
   VEHICLE SPD((1))	Wheel speed sensor (FR) reading / min.: 0 km/h (0 MPH, max.: 326 km/h (202 MPH)	Actual vehicle speed
   (1) ABS Data

   1. NG GO TO FLOW CHART OR PROBLEM SYMPTOMS TABLE (ABS WITH EBD & BA TRAC & VSC SYSTEM) (See  HOW TO PROCEED WITH TROUBLESHOOTING  . 
   2. OK: GO TO NEXT STEP 
2. 2 CHECK HARNESS AND CONNECTOR(SKID CONTROL ECU - COMBINATION METER ASSY)
