Inspection Procedure

NOTE: When replacing the skid control ECU, perform initialization of linear solenoid valve and calibration (see INITIALIZATION  ).
  1. CHECK DLC3 (TS VOLTAGE) 
    1. Turn the power switch ON (READY).
    2. Measure the voltage of the DLC3.

      Standard voltage 

      TESTER CONNECTION SPECIFIED CONDITION

      Tester Connection Specified Condition
      D1-12 (TS) - D1-4 (CG) 10 to 14 V

    NG : Go to step   3

  2. CHECK WIRE HARNESS (SKID CONTROL ECU - DLC3) 
    1. Disconnect the S8 ECU connector.
    2. Measure the resistance of the wire harness side connectors.

      Standard resistance 

      TESTER CONNECTION SPECIFIED CONDITION

      Tester Connection Specified Condition
      S8-32 (TS) - D1-12 (TS) Below 1 Ω
      S8-32 (TS) - Body ground 10 kΩ or higher

    NG : REPAIR OR REPLACE HARNESS AND CONNECTOR
