2. Disconnect the yaw rate sensor connector (D28).
3. Measure the resistance according to the value(s) in the table below.

   Standard resistance

   Tester Connection	Condition	Specified value
   D28-2 (CANL) - D28-3 (CANH)	Ignition switch off	54 to 69 Ω

NG → REPAIR OR REPLACE YAW RATE SENSOR SUB BUS LINE OR CONNECTOR 

OK: Go to next step 

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

   Standard resistance

   Tester Connection	Condition	Specified Condition
   D28-1 (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 Condition
   D28-5 (IG) - Body ground	Ignition switch ON	10 to 14 V

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK → See step   3
