Shifter ASMT: Testing and Inspection

Selector Lever Voltage Supply, Checking

Special tools, testers and auxiliary items required
- Multimeter.
- Wiring diagram.

Test requirements
- The Direct Shift Gearbox (DSG) Mechatronic J743 fuses OK.
- Battery voltage at least 12.5 volts.
- All electrical consumers such as, lights and rear window defroster, switched off.
- Selector lever in "P".
- A/C switched off.
- Ground (GND) connections between engine/transmission/chassis OK.
- Ignition switched off.

Test procedure
- Perform a preliminary check to verify the customers complaint. General Diagnosis

Start diagnosis
- Remove the selector mechanism, far enough to gain access to the Selector Lever E313 electrical harness connector - A -.







- Disconnect the Selector Lever E313 electrical harness connector - A -.

Checking voltage supply, terminal 30
- Using a Multimeter, check the Selector Lever E313 electrical harness connector terminals 10 to 1 for voltage.

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 specified value was obtained:

Checking voltage supply, terminal 15
- Using a Multimeter, check the Selector Lever E313 electrical harness connector terminals 9 to 1 for voltage.

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:
- Erase the DTC memory. Diagnostic Mode 04 - Erase DTC Memory
- Perform a road test to verify repair.

If the DTC does not return:
Repair complete, Generate readiness code. Readiness Code
- End diagnosis.

If the DTC does return and no malfunction is detected in the wiring and the voltage supply was OK:
- Replace the Selector Lever E313.
- Assembly is performed in the reverse of the removal.

Final procedures
After repair work, the following work steps must be performed in the following sequence:
1. Check the DTC memory. Diagnostic Mode 03 - Read DTC Memory
2. If necessary, erase the Direct Shift Gearbox (DSG) Mechatronic J743 memory.
3. If the DTC memory was erased, generate readiness code. Readiness Code

- End of diagnosis.
