DTC	Error Message	Diagnostic Procedure	Malfunction Criteria and Threshold Value	Secondary Parameters with Enable Conditions	Monitoring Time Length	Frequency of checks, MIL Illum
U0001	High Speed CAN Communication Bus	-- Check the CAN-Bus terminal resistance. Refer to CAN-BUS TERMINAL RESISTANCE, CHECKING .	CAN message, No feedback	Battery voltage, 9.49-16.5 V	0.5 Seconds	2 DCY
U0100	Lost Communication with ECM/PCM A	-- Check the CAN-Bus terminal resistance. Refer to CAN-BUS TERMINAL RESISTANCE, CHECKING .	Failure of all CAN engine messages, Time out more than 490 ms Failure of all CAN engine messages but not all CAN messages, Time out more than 1010 ms	No bus off error No error failure of all CAN messages No error failure of all CAN engine messages Terminal 15 Voltage, > 9 V for more than 500 ms > 500 ms after reset	1 Second
U0101	Lost Communication with TCM	-- Check the CAN-Bus terminal resistance, Direct Shift Gearbox (DSG) Mechatronic -J743- to Motronic Engine Control Module (ECM) - J623-. Refer to DSG MECHATRONIC J743 CAN-BUS TERMINAL RESISTANCE, CHECKING .	Checksum check Failed Message counter check failed Time out check No message received by ECM	-	0.5 Seconds	2 DCY
U0302	Software Incompatibility with Transmission Control Module	-- Replace the Direct Shift Gearbox (DSG) Mechatronic -J743-. Refer to DSG TRANSMISSION MECHATRONIC -J743-, TRANSMISSION REMOVED .	AT vehicle ECM coded as MT vehicle	-	800 ms	-
U0404	Invalid Data Received From Gear Shift Control Module	-- Check the CAN-Bus terminal resistance, Selector Lever -E313- to Motronic Engine Control Module (ECM) - J623-. Refer to CAN-BUS TERMINAL RESISTANCE AND SELECTOR LEVER E313 TO MOTRONIC ENGINE CONTROL MODULE J623, CHECKING .	If the value of message counter is permanent, constant, or change exceeds a threshold, increment an event counter maximum change of message counter > 5	No failure of selector lever CAN messages Terminal 15 voltage > 4 V for more than 500 ms	50 ms	Continuous 2 DCY
