INSPECTION PROCEDURE

NOTICE:
  1. After replacing the brake actuator assembly, perform calibration (Toyota Fortuner RM000000XHR06WX.html).
  2. Before disconnecting the connector, make sure that there are no problems with the connection.
  3. After disconnecting the connector, make sure that the connector case and terminals are not deformed or corroded.
1.CHECK TERMINAL VOLTAGE (EXI TERMINAL)

  1. Set the vehicle to the center differential lock state using the transfer shift lever.

  1. Turn the ignition switch off.

REPLACE BRAKE ACTUATOR ASSEMBLY (Toyota Fortuner RM0000010K0010X.html)

3.CHECK HARNESS AND CONNECTOR (EXI CIRCUIT)

  1. Turn the ignition switch off.

  1. Disconnect the skid control ECU (brake actuator assembly) connector.

  1. Disconnect the center differential lock position switch (No. 3 transfer indicator switch) connector.

  1. Disconnect the C28 combination meter connector.

  1. Measure the resistance according to the value(s) in the table below.

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Condition
    S25-20 (EXI) - T4-2
    		Always
    		Below 1 Ω
    S25-20 (EXI) - Body ground
    		Always
    		10 kΩ or higher
    T4-1 - Body ground
    		Always
    		Below 1 Ω
