- Before measuring the resistance of the CAN bus, turn the ignition switch
off and leave the vehicle for 1 minute or more without operating the key or
any switches, or opening or closing the doors. After that, disconnect the cable
from the negative (-) auxiliary battery terminal and leave the vehicle for 1
minute or more before measuring the resistance.
- After the ignition switch is turned off, there may be a waiting time before
disconnecting the negative (-) auxiliary battery terminal.
