INSPECTION PROCEDURE

  • HINT:
  • Operating the ignition switch, any switches or any doors triggers related ECU and sensor communication with the CAN, which causes resistance variation.
1.PRECAUTION
  • NOTICE:
  • After turning the ignition 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 ().
NEXT
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.

  • CAUTION:
  • For vehicles with an SRS system:
  • Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.
  • NOTICE:
  • When disconnecting the cable, some systems need to be initialized after the cable is reconnected ().
