CAN COMMUNICATION SYSTEM(for LHD without Central Gateway ECU) TERMINALS OF ECU
Operating the ignition switch, any switches or any doors triggers related ECU and sensor communication with the CAN, which causes resistance variation.
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.
CAUTION:Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the airbag system.
Note:Before measuring the resistance, leave the vehicle for at least 1 minute and do not operate the ignition switch, any switches or any doors. If doors need to be opened in order to check connectors, open the doors and leave them open.
After turning the cable disconnected from negative (-) battery terminal, 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.
When disconnecting the cable, some systems need to be initialized after the cable is reconnected.
