Tiptronic Switch F189, Checking

Special tools, testers and auxiliary items required 

• Multimeter
• Wiring diagram

Requirements 

• Fuse S231 OK.
• The Control Module with indicator unit in the Instrument Cluster Control Module J285 must be OK.
• The selector lever cable adjustment OK.
• The battery voltage must be at least 12.5 Volts.

• All electrical consumers must be switched off.
• The parking brake must be engaged.
• The selector lever must be in the "P" position.
• The Ground (GND) connections to transmission must be OK.

Procedure 

• Switch the ignition on.
• Depress the brake pedal and maintain depressed.
• Shift the selector lever into all positions.

The selector lever position must correspond with the Tiptronic Switch F189 indicator display unit.

• Switch the ignition off.

If the selector lever position does not correspond with the Tiptronic Switch F189 indicator display unit:

• Disconnect the Tiptronic Switch F189 electrical harness connector - 1  -.
• Check the electrical harness connector for damage, corrosion, loose or broken terminals.
• Repair any damage found to the electrical harness connector.

If the electrical harness connector is not OK:

• Repair the malfunction.

If the electrical harness connector is OK:

Checking voltage 

• Switch the ignition on.
• Using a multimeter, check the Tiptronic Switch F189 electrical harness connector terminal T10/7 to Ground (GND) for voltage.

Specified value, Battery voltage.

• Switch the ignition off.

If the specified value was not obtained:

• If necessary, repair the faulty wiring connection.

If the specified value was obtained:

Checking Ground (GND) 

• Using a multimeter, check the Tiptronic Switch F189 electrical harness connector terminal 10/31 to Ground (GND) connection for resistance.

Specified value: 1.5 Ω Max.

If the specification was not obtained:

• Check the wiring for a short circuit to each other, Battery (+), and Ground (GND).
• If necessary, repair the faulty wiring connection.

If no malfunction was found in the wiring and the resistance was OK:

Checking wiring 

If the manufacturers test box is being used, perform the following step.

Test Box 105 Pin VAG1598/31

If the manufacturers test box is not being used, perform the following step.

• Remove the Transmission Control Module (TCM) J217. Refer to → Transmission Control Module (TCM) J217, Replacing .

• Using a multimeter, check the Tiptronic Switch F189 electrical harness connector terminals to the Transmission Control Module (TCM) J217 electrical harness connector terminals for an open circuit.

Specified value: 1.5 Ω Max.

If the specification was not obtained:

• Check the wiring for a short circuit to each other, Battery (+), and Ground (GND).
• If necessary, repair the faulty wiring connection.

If no malfunction was found in the wiring and the resistance was not OK:

• Replace the Tiptronic Switch F189. Refer to
  • for 5 SPD. AUTOMATIC TRANSMISSION 01V
  • for 5 SPD. AUTOMATIC TRANSMISSION 01V FRONT AND ALL WHEEL DRIVE - INTERNAL COMPONENTS, SERVICING
  • for 6 SPD. AUTOMATIC TRANSMISSION 09L ALL WHEEL DRIVE
  , Tiptronic Switch F189, Removing and Replacing.

If no malfunction is found in the wiring and the resistance was OK:

• Replace the Transmission Control Module (TCM) J217. Refer to → Transmission Control Module (TCM) J217, Replacing .

Final procedures 

1. Check the DTC memory.
2. If necessary, erase the DTC memory. Refer to Diagnostic Mode 04 - Reset/Delete Diagnostic Data .
3. If the DTC memory was erased, generate readiness code. Refer to Readiness Code Description .
