CAN COMMUNICATION SYSTEM(for RHD) TERMINALS OF ECU

Tech Tips

Operating the power switch, any switches or any doors triggers related ECU and sensor communication with the CAN, which causes resistance variation.


  1. DISCONNECT CABLE FROM NEGATIVE AUXILIARY BATTERY TERMINAL


    1. Disconnect the cable from the negative (-) auxiliary battery terminal before measuring the resistances of the CAN main wire and CAN branch wire.

      CAUTION:

      Wait at least 90 seconds after disconnecting the cable from the negative (-) auxiliary battery terminal to disable the SRS system.

      Note


      • Before measuring the resistance, leave the vehicle for at least 1 minute and do not operate the power 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 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 auxiliary battery terminal notice before proceeding with work.

      • When disconnecting the cable, some systems need to be initialized after the cable is reconnected.
