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. |
