CAUTION / NOTICE / HINT

Note


  • To measure the resistance of the CAN bus, turn the power switch off, wait at least 1 minutes without operating any keys or switches or opening or closing the doors, disconnect the auxiliary battery, wait at least 1 minutes again, and then measure the resistance.

  • After turning the power switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work.
