INSPECTION PROCEDURE

NOTICE:
  1. Before disconnecting the connector, make sure that there are no problems with the connection.
  2. 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 4WD state using the transfer shift lever.

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

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

    Standard Voltage:
    Tester Connection
    		Condition
    		Specified Condition
    A13-17 (EXI) - Body ground
    1. Ignition switch ON
    2. Transfer shift position H4
    		Below 1.5 V

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

  1. Set the vehicle to the 2WD state using the transfer shift lever.

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

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

    Standard Voltage:
    Tester Connection
    		Condition
    		Specified Condition

3.CHECK HARNESS AND CONNECTOR (EXI CIRCUIT)

  1. Turn the ignition switch off.

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

  1. w/ Differential Vacuum Actuator Assembly:
    Disconnect the 4WD detection switch (differential vacuum actuator assembly) connector.
    w/o Differential Vacuum Actuator Assembly:
    Disconnect the 4WD position switch (No. 3 transfer indicator switch) connector.

  1. w/ Differential Vacuum Actuator Assembly:
    Disconnect the 4 wheel drive control ECU connector.

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

    Standard Resistance:
    w/ Differential Vacuum Actuator Assembly:
    Tester Connection
    		Condition
    		Specified Condition
    A13-17 (EXI) - C31-3 (ADD)
    		Always
    		Below 1 Ω
    A13-17 (EXI) - C37-8 (ADD)
    		Always
    		Below 1 Ω
    A13-17 (EXI) - Body ground
    		Always
    		10 kΩ or higher
    C31-4 (GND) - Body ground
    		Always
    		Below 1 Ω
    w/o Differential Vacuum Actuator Assembly:
    Tester Connection
    		Condition
    		Specified Condition
    A13-17 (EXI) - C28-2
    		Always
    		Below 1 Ω
    A13-17 (EXI) - Body ground
    		Always
    		10 kΩ or higher
    C28-1 - Body ground
    		Always
    		Below 1 Ω
