caution | During diagnosis, a diagnosis code
associated with other system may be set when the ignition
switch is turned on with connector(s) disconnected. On
completion, confirm all systems for diagnosis code(s). If
diagnosis code(s) are set, erase them all. |
warning | Since the radiator fan rotates during CAN
bus line diagnostics, make sure that no one is servicing the
engine compartment before diagnosing the CAN bus line. Since
the CAN communication stops when diagnosing the CAN bus
line, the ETACS-ECU detects the time-out of the engine-ECU,
and activates the radiator fan to prevent overheating as
fail-safe. |
