Component Tests and General Diagnostics

ETACS (ELECTRONIC TIME AND ALARM CONTROL SYSTEM)

INSPECTION
Trouble diagnostics when using scan tool.
1. If the self-diagnostic function is in operation, CAN communication stops and LIN communication is converted into self-diagnostic communication.
2. Only BCM communicates directly with scan tool, and the other units perform self-diagnostic function by BCM through the mediator of CAN or LIN.
