INSPECTION PROCEDURE

1.CHECK HARNESS AND CONNECTOR (BETWEEN YAW RATE AND DECELERATION SENSOR AND IG CIRCUIT)


    F045082E01

  1. Disconnect the yaw rate and deceleration sensor connector.

  1. Turn the ignition switch on.

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

    Voltage:
    Tester Connection
    		Specified Condition
    Y1-5 (IG) - Body ground
    		10 to 14 V



NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
OK


2.CHECK HARNESS AND CONNECTOR (BETWEEN YAW RATE AND DECELERATION SENSOR AND BODY GROUND)


    F045082E04

  1. Disconnect the yaw rate and deceleration sensor connector.

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

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



NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
OK

REPLACE YAW RATE AND DECELERATION SENSOR
