Center Airbag 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 (AIRBAG SENSOR ASSEMBLY BRANCH WIRE)
- Disconnect the airbag sensor assembly connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Switch Condition Specified Condition D150-13 (CANH) - D150-22 (CANL) Ignition switch off 54 to 69 Ω TEXT IN ILLUSTRATION*a Front view of wire harness connector
(to Airbag Sensor Assembly)
Result:
NG
REPAIR OR REPLACE CAN BRANCH WIRE CONNECTED TO AIRBAG SENSOR ASSEMBLY (CAN-H, CAN-L)
Result:
OK
See step 4
- Disconnect the airbag sensor assembly connector.
- CHECK HARNESS AND CONNECTOR (AIRBAG SENSOR ASSEMBLY - 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 airbag sensor assembly connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition D150-25 (E1) - Body ground Always Below 1 Ω D150-26 (E2) - 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 D150-21 (IG2) - Body ground Ignition switch ON 11 to 14 V TEXT IN ILLUSTRATION*a Front view of wire harness connector
(to Airbag Sensor Assembly)
Result:
OK
REPLACE AIRBAG SENSOR ASSEMBLY
(Refer to REMOVAL [12/2015 - ] )
Result:
NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
- Connect the cable to the negative (-) battery terminal.
