      Result 

      RESULT REFERENCE

      Result Proceed to
      CAN communication DTC Is not output. A
      CAN communication DTC Is output. B

      B: GO TO CAN COMMUNICATION SYSTEM  (See HOW TO PROCEED WITH TROUBLESHOOTING )

      A: Go to next step 

  2. PERFORM ACTIVE TEST USING TECHSTREAM (SPEED METER OPERATION) 
    1. Connect the Techstream to the DLC3.
    2. Turn the ignition switch to ON.
    3. Turn the Techstream on.
    4. Enter the following menus: Body Electrical / Combination Meter / Active Test.

      OK: 

      Vehicle speed displayed on the Techstream is almost the same as the actual vehicle speed measured using a speedometer tester (calibrated chassis dynamometer). 

      NG: Go to step 4 

      OK: REPLACE COMBINATION METER  (See REMOVAL )

  4. READ VALUE USING TECHSTREAM (FR/FL/RR/RL WHEEL SPEED) 
    1. Connect the Techstream to the DLC3.
    2. Turn the ignition switch to ON.
    3. Turn the Techstream on.
    4. Enter the following menus: Chassis / ABS/VSC/TRAC / Data List.

      OK: 

      Vehicle speed displayed on the Techstream is almost the same as the actual vehicle speed measured using a speedometer tester (calibrated chassis dynamometer). 

      Result 

      RESULT REFERENCE

      Result Proceed to
      OK A
      NG (w/o VSC) B
      NG (w/ VSC) C

      B: GO TO BRAKE CONTROL SYSTEM (w/o VSC)  (See HOW TO PROCEED WITH TROUBLESHOOTING )

      C: GO TO BRAKE CONTROL SYSTEM (w/ VSC)  (See HOW TO PROCEED WITH TROUBLESHOOTING )

      A: Go to next step 

  5. REPLACE SKID CONTROL ECU 
    1. Replace the skid control ECU with a new or a known good one (See REMOVAL (w/o VSC), REMOVAL (w/ VSC)).

      OK: 

      The operation of the speedometer returns to normal. 

      NG: REPLACE COMBINATION METER  (See REMOVAL )

      OK: END
