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. |
