WIRING DIAGRAM

INSPECTION PROCEDURE

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

1. Turn the ignition switch off.

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

3. 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)

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

2. 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
