INSPECTION PROCEDURE

NOTICE:
* Turn the ignition switch off before measuring the resistance of the main wire and the branch wire.
* After the ignition switch is turned off, check that the key reminder warning system and light reminder buzzer are not in operation.
* 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.
