Yaw Rate Sensor Communication Stop Mode [12/2015 - 11/2017]: Procedure
- PRECAUTION NOTE:
After turning the ignition switch off, waiting time may be required before disconnecting the cable from the battery terminal. Therefore, make sure to read the disconnecting the cable from the battery terminal notice before proceeding with work (Refer to PRECAUTION [12/2015 - 08/2016] , or refer to PRECAUTION [08/2016 - ] ).
Result:
NEXT
See step 2
- DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL
- Disconnect the cable from the negative (-) battery terminal before measuring the resistances of the main wire and the branch wire.WARNING:
Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.
NOTE:When disconnecting the cable, some systems need to be initialized after the cable is reconnected (Refer to INITIALIZATION [12/2015 - 08/2016] , or refer to INITIALIZATION [08/2016 - 11/2017] )
Result:
NEXT
See step 3
- Disconnect the cable from the negative (-) battery terminal before measuring the resistances of the main wire and the branch wire.
- CHECK CAN BUS LINE FOR DISCONNECTION (YAW RATE SENSOR BRANCH WIRE)
- Disconnect the yaw rate sensor connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Switch Condition Specified Condition L6-3 (CANH) - L6-2 (CANL) Ignition Switch off 54 to 69 Ω TEXT IN ILLUSTRATION*a Front view of wire harness connector
(to Yaw Rate Sensor)
Result:
NG
REPAIR OR REPLACE CAN BRANCH WIRE CONNECTED TO YAW RATE SENSOR (CAN-H, CAN-L)
Result:
OK
See step 4
- Disconnect the yaw rate sensor connector.
- CHECK HARNESS AND CONNECTOR (YAW RATE SENSOR - POWER SOURCE)
- Connect the cable to the negative (-) battery terminal.NOTE:
When disconnecting the cable, some systems need to be initialized after the cable is reconnected (Refer to INITIALIZATION [12/2015 - 08/2016] , or refer to INITIALIZATION [08/2016 - 11/2017] )
- Disconnect the yaw rate sensor connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition L6-1 (GND) - Body ground Always Below 1 Ω - Measure the voltage according to the value(s) in the table below.
Standard Voltage
Tester Connection Switch Condition Specified Condition L6-4 (IG) - Body ground Ignition switch ON 11 to 14 V TEXT IN ILLUSTRATION*a Front view of wire harness connector
(to Yaw Rate Sensor)
Result:
OK
REPLACE YAW RATE SENSOR
(Refer to REMOVAL [12/2015 - 11/2017] )
Result:
NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
- Connect the cable to the negative (-) battery terminal.
