INSPECTION PROCEDURE

1.CHECK CONNECTOR CONNECTION CONDITION (TORQUE SENSOR - POWER STEERING ECU)

  1. Check the installation condition of the torque sensor connector.

    OK:
    Torque sensor connector is securely connected to the power steering ECU.


NG
CONNECT CONNECTOR SECURELY
OK


2.CHECK POWER STEERING ECU

  1. Turn the ignition switch on (IG).

  1. Measure the voltage of the ECU.

    Standard voltage:
    Tester Connection
    		Condition
    		Specified Condition
    h2-4 (TRQF) - h2-1 (TRQG)
    		Always
    		3.35 to 3.37 V
    h2-3 (TRQV) - h2-1 (TRQG)
    		Always
    		8.5 to 10.5 V


NG
REPLACE POWER STEERING ECU
OK


3.INSPECT TORQUE SENSOR

  1. Turn the ignition switch on (IG).

  1. Measure the voltage of the ECU.

    Standard voltage:
    Tester Connection
    		Condition
    		Specified Condition
    h2-6 (TRQ1) - h2-1 (TRQG)
    		Steering wheel not turned (without load)
    		2.3 to 2.7 V
    Steering wheel turned to right with vehicle stopped
    		2.5 to 4.04 V
    Steering wheel turned to left with vehicle stopped
    		0.95 to 2.5 V
    h2-2 (TRQ2) - h2-1 (TRQG)
    		Steering wheel not turned (without load)
    		2.3 to 2.7 V
    Steering wheel turned to right with vehicle stopped
    		0.95 to 2.5 V
    Steering wheel turned to left with vehicle stopped
    		2.5 to 4.04 V

  1. Add the voltage measured at terminal TRQ1 minus 2.5 V to the voltage measured at terminal TRQ2 minus 2.5 V.

    OK:
    Below 0.4 V (Absolute value)
