INSPECTION PROCEDURE

HINT:
Operating the ignition switch, any switches or any doors triggers related ECU and sensor communication with the CAN, which causes resistance variation.
1.DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL

  1. Disconnect the cable from the negative (-) battery terminal before measuring the resistances of the main wire and the branch wire.

    CAUTION:
    Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.
    NOTICE:
    When disconnecting the cable from the negative (-) battery terminal, some systems need to be initialized after the cable is reconnected (Toyota Fortuner RM000002HD2002X.html).

  1. Disconnect the Y1 yaw rate sensor connector.

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

    Standard Resistance:
    Tester Connection
    		Switch Condition
    		Specified Condition
    Y1-3 (CANH) - Y1-2 (CANL)
    		Ignition switch off
    		54 to 69 Ω

REPAIR OR REPLACE YAW RATE SENSOR BRANCH WIRE OR CONNECTOR (CANH, CANL)
OK


3.CHECK HARNESS AND CONNECTOR (YAW RATE SENSOR - BATTERY AND BODY GROUND)

  1. Reconnect the cable to the negative (-) battery terminal.

    NOTICE:
    When disconnecting the cable from the negative (-) battery terminal, some systems need to be initialized after the cable is reconnected (Toyota Fortuner RM000002HD2002X.html).

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

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Condition
    Y1-1 (GND) - Body ground
    		Always
    		Below 1 Ω

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

    Standard Voltage:
    Tester Connection
    		Switch Condition
    		Specified Condition
    Y1-4 (IG) - Body ground
    		Ignition switch ON
    		11 to 14 V
