INSPECTION PROCEDURE

NOTICE:
  1. Turn the ignition switch off before measuring the resistance of the main wire and the branch wire.
  2. After the ignition switch is turned off, check that the key reminder warning system and light reminder buzzer are not in operation.
  3. Before measuring the resistance, leave the vehicle for at least 1 minute and do not operate the ignition switch, any switches or doors. If doors need to be opened in order to check connectors, open the doors and leave them open.
HINT:
Operating the ignition switch, any switches or any doors triggers related ECU and sensor communication with the CAN, which causes resistance variation.
1.DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL

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

    CAUTION:
    Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.
    NOTICE:
    1. w/ Navigation System (for HDD):
      After the ignition switch is turned off, the HDD navigation system requires approximately a minute to record various types of memory and settings. As a result, after turning the ignition switch off, wait a minute or higher before disconnecting the cable from the negative (-) battery terminal.
    2. When disconnecting the cable, some systems need to be initialized after the cable is reconnected.
