Multi-media Module Receiver Assembly Communication Stop Mode [09/2015 - ]: Procedure
- PRECAUTION NOTE:
After turning the engine 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 [09/2015 - ] ).

See step 2
- DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL
- Disconnect the cable from the negative (-) 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 (-) 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 - ] ).

- Disconnect the multi-media module receiver assembly connector.
- CHECK HARNESS AND CONNECTOR (MULTI-MEDIA MODULE RECEIVER ASSEMBLY - BATTERY AND BODY GROUND)
- 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 [09/2015 - ] ).
