INSPECTION PROCEDURE

1.CHECK CAN BUS LINE FOR DISCONNECTION (YAW RATE SENSOR SUB BUS LINE)

  1. Turn the ignition switch off.



    G026359E16

  1. Disconnect the yaw rate sensor connector (Y1).

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

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Value
    Y1-3 (CANH) - Y1-2 (CANL)
    		Disconnect the negative auxiliary battery cable
    		54 to 69 Ω



NG
REPAIR OR REPLACE YAW RATE SENSOR SUB BUS LINE OR CONNECTOR (CAN-H, CAN-L)
OK


2.CHECK WIRE HARNESS (IG, GND)


    G026359E17

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

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Value
    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
    		Condition
    		Specified Value
    Y1-5 (IG) - Body ground
    		Ignition switch on
    		10 to 14 V



NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
OK

REPLACE YAW RATE SENSOR
