Inspection Procedure

NOTE: When replacing the ABS and TRACTION actuator assembly, perform zero point calibration (See CALIBRATION  ).
  1. PERFORM ACTIVE TEST BY INTELLIGENT TESTER (SLIP INDICATOR LIGHT) 
    1. Connect the intelligent tester to the DLC3.
    2. Start the engine.
    3. Select the "SLIP INDI LIGHT" in the ACTIVE TEST and operate the SLIP indicator light by the intelligent tester.

    4. Check that "ON" and "OFF" of the SLIP indicator light are indicated on the combination meter when using the intelligent tester.

      OK: Turn the SLIP indicator light on or off in accordance with the intelligent tester. 

    NG: Go to step 2 

    OK : REPLACE ABS AND TRACTION ACTUATOR ASSEMBLY 

  2. INSPECT TRACTION CONTROL SWITCH 
    1. Remove the traction control switch.
