DTC's relating to CAN-BUS (U0121-U1110):

CAUTION: During diagnosis, a DTC associated with other system may be set when the ignition switch is turned on with connector(s) disconnected. On completion, confirm all systems for DTCs. If DTCs are set, erase them all.

NOTE: Do not replace the engine control module (ECM) [M/T] or the powertrain control module (PCM) [A/T] until a through terminal check reveals there are no short/open circuits.

NOTE: Check that the ECM [M/T] or the PCM [A/T] ground circuit is normal before checking for the cause of the problem.

NOTE: After the ECM [M/T] or the PCM [A/T] detects a malfunction, a diagnostic trouble code is recorded the next time the engine is started and the same malfunction is re-detected. However, for items marked with a " * ", the diagnostic trouble code is recorded on the first detection of the malfunction.
