Can Communication System -- Terminals Of Ecu |
- 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.
- 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.
- HINT:
- Operating the ignition switch, any switches or any doors triggers related ECU and sensor communication with the CAN, which causes resistance variation.
