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
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.
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.
