Direct Shift Gearbox (DSG) Mechatronic J743 electrical harness connector terminals
18 to 16
18 to 19

Specified value: battery voltage.

If the specified value was not obtained:

-

Check the wiring connection for an open circuit, short circuit to Battery (+) or Ground (GND).

-

Check the wiring connection for damage, corrosion, loose or broken terminals.

-

If necessary, repair the faulty wiring connection.

If the wiring and voltage were OK:

-

Replace Direct Shift Gearbox (DSG) Mechatronic J743.

Final procedures

After the repair work, the following work steps must be performed in the following sequence:

1. Check the DTC memory. 
2. If necessary, erase the DTC memory. 
3. If the DTC memory was erased, generate readiness code. See: Powertrain Management/Computers and Control Systems/Testing and

Inspection/Monitors, Trips, Drive Cycles and Readiness Codes

-

End of diagnosis.
