Yaw Rate Sensor Communication Stop Mode [03/2014 - ]: Procedure
- CHECK CAN BUS WIRE FOR DISCONNECTION (YAW RATE SENSOR BRANCH WIRE)
- Turn the engine switch off.
- Disconnect the yaw rate and acceleration sensor connector.TEXT IN ILLUSTRATION
*1 Front view of wire harness connector
(to Yaw Rate Sensor) - Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Switch Condition Specified Condition F28-3 (CANH) - F28-2 (CANL) Engine switch off 54 to 69 Ω
NG → REPAIR OR REPLACE CAN BUS BRANCH WIRE OR CONNECTOR (YAW RATE AND ACCELERATION SENSOR BRANCH WIRE)
OK: Go to next step
- CHECK HARNESS AND CONNECTOR (POWER SOURCE TERMINAL)
- Turn the engine switch on (IG).
- Measure the voltage according to the value(s) in the table below.
Standard Voltage
Tester Connection Switch Condition Specified Condition F28-4 (IG) - Body ground Engine switch on (IG) 11 to 14 V TEXT IN ILLUSTRATION*1 Front view of wire harness connector
(to Yaw Rate Sensor)
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR (POWER SOURCE CIRCUIT)
OK: Go to next step
- CHECK HARNESS AND CONNECTOR (GROUND TERMINAL)
- Turn the engine switch off.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition F28-1 (GND) - Body ground Always Below 1 Ω TEXT IN ILLUSTRATION*1 Front view of wire harness connector
(to Yaw Rate Sensor)
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR (GROUND CIRCUIT)
OK → See step 4
- REPLACE YAW RATE SENSOR ASSEMBLY. Refer to REMOVAL [03/2014 - ]
