Test Procedure

Step	Procedure	Result / Action to Take
1	PERFORM: Preliminary Check to verify the customers complaint. Refer to PRELIMINARY CHECK -- Was Complaint verified?	YES: Go to Step 2 NO: Gather more Information from customer about the complaint
2	Remove the transmission control module. Refer to the appropriate service information for removal and installation procedures. Disconnect the transmission control module electrical harness connector. Check the electrical harness connector for damage, corrosion, loose, or broken terminals. Repair as necessary. -- Do any DTC's return:	YES: GO TO: Step 3 NO: GO TO: Step 5
3	The ECM must remain connected for the following step. The central terminal resistor is located in the ECM. Using a multimeter, check the DSG Transmission Mechatronic -J743- electrical harness connector terminals T20e / 15 to T20e / 10 for resistance. Specified value: 60 to 72 Ω (at approx. 20° C) -- Was Value obtained?	YES: GO TO: Step 4 NO: CHECK: wiring for open, high resistance, short or electrical connector for damage, corrosion, loose or broken terminals REPAIR: faulty wiring or connector GO TO: Step 5
4	REMOVE: Engine Control Module - J623-. Refer to appropriate service information. Using a multimeter, check the CAN bus circuit between terminal T20e / 15 of the DSG Transmission Mechatronic -J743- and terminal T94 / 68 of the Engine Control Module -J623- for resistance. Using a multimeter, check the CAN bus circuit between terminal T20e / 10 of the DSG Transmission Mechatronic -J743- and terminal T94 / 67 of the Engine Control Module -J623- for resistance. SPECIFIED VALUE: 0.5 Ω (± 0.3 Ω) -- Was Value obtained?	YES: Remove the Engine Control Module -J623-. Refer to the appropriate service information for removal and installation procedures. Check each CAN circuit for a short to ground, short to voltage, open circuit or high resistance. If no malfunction is found in the wiring: Replace the DSG Transmission Mechatronic -J743-. Refer to the appropriate service information for removal and installation procedures. GO TO: Step 5 NO: If the specified resistance value was not obtained and no malfunction is found in the wiring: Replace the Engine Control Module -J623-. Refer to the appropriate service information for removal and installation procedures. GO TO: Step 5
5	Final Procedure Perform a road test to verify repair. Do any DTC's return:	YES: Check the DTC memory. Refer to DIAGNOSTIC MODE 03 - READ DTC MEMORY . Perform the diagnostic procedure for that DTC. NO: Repair is complete, Generate readiness code. Refer to READINESS CODE . Return vehicle to Customer
