Specified value: 1.5 Ohms Max.

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, lose or broken terminals.

-

If necessary, repair the faulty wiring connection.

If no malfunction is found in the wiring:

-

Erase the DTC memory.  

-

Perform a road test to verify repair.

If the DTC does not return:
Repair complete, Generate readiness code.  See: Powertrain Management/Computers and Control Systems/Testing and Inspection/Monitors, Trips, Drive
Cycles and Readiness Codes

-

End diagnosis.

If the DTC does return and no malfunction is detected in the wiring and the voltage supply was OK:

-

Replace the Direct Shift Gearbox (DSG) Mechatronic J743.

Final procedures

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

1. Check the DTC memory.  
2. If necessary, erase the Direct Shift Gearbox (DSG) Mechatronic J743 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.
