Multi-media Module Receiver Assembly Communication Stop Mode [09/2015 - ]: Procedure
- PRECAUTION NOTE:
After turning the power switch off, waiting time may be required before disconnecting the cable from the auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the auxiliary battery terminal notice before proceeding with work (Refer to PRECAUTION [09/2015 - ] ).

See step 2
- DISCONNECT CABLE FROM NEGATIVE AUXILIARY BATTERY TERMINAL
- Disconnect the cable from the negative (-) auxiliary battery terminal before measuring the resistances of the CAN main wire and the CAN branch wire.WARNING:
Wait at least 90 seconds after disconnecting the cable from the negative (-) auxiliary 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 [09/2015 - ] ).
