Solenoid Valves in Valve Body, Checking
WARNING: This page is about a different car, the 2006 Audi A4, 2005 Audi A4, 2004 Audi A4, 2003 Audi A4, and 2002 Audi A4. However, it is still accessible from the selected car via links, so may be relevant.
This procedure is used to diagnose all Solenoid Valves in the valve body.
Special tools, testers and auxiliary items required
- Multimeter
- Wiring diagram
Requirements
- The Solenoid Valve fuses 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 elector lever must be in the "P" position.
- The Ground (GND) connections to transmission must be OK.
Procedure
- Disconnect the Solenoid Valve electrical harness connector.
- Check the electrical harness connector for damage, corrosion, lose 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 resistance
- Using a multimeter, check the Solenoid Valve electrical harness connector terminals at the Solenoid Valve electrical harness connector for resistance.
| Solenoid Valve | Electrical Harness Connector Terminal | Specified Value (Approx. 20°C) |
|---|---|---|
| Solenoid Valve 1 N88 | 12 to 8 | 55.0 - 65.0 Ω |
| Solenoid Valve 2 N89 | 12 to 9 | 55.0 - 65.0 Ω |
| Solenoid Valve 3 N90 | 12 to 4 | 55.0 - 65.0 Ω |
| Automatic Transmission Pressure Regulating Valve 1 N215 | 12 to 2 | 4.5 - 6.5 Ω |
| Automatic Transmission Pressure Regulating Valve 2 N216 | 12 to 3 | 55.0 - 65.0 Ω |
| Automatic Transmission Pressure Regulating Valve 3 N217 | 12 to 7 | 4.5 - 6.5 Ω |
| Automatic Transmission Pressure Regulating Valve 4 N218 | 12 to 11 | 55.0 - 65.0 Ω |
If any of the specified values are not obtained:
- Replace the faulty Solenoid Valve/Regulating Valve. Refer to , Removing and Replacing.
If the specified values are obtained:
Checking wiring
- Install the Adapter F/VAG1598 (68 Pin) VAG1598/22. 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
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 Solenoid Valve electrical harness connector terminals to the Transmission Control Module (TCM) J217 electrical harness connector terminals for an open circuit.
| Solenoid Valve | Electrical Harness Connector Terminal | Transmission Control Module (TCM) J217 electrical connector terminals or test box sockets |
|---|---|---|
| Solenoid Valve 1 N88 | 12 | 52 |
| 8 | 30 | |
| Solenoid Valve 2 N89 | 12 | 52 |
| 9 | 33 | |
| Solenoid Valve 3 N90 | 12 | 52 |
| 4 | 32 | |
| Automatic Transmission Pressure Regulating Valve 1 N215 | 12 | 52 |
| 2 | 5 | |
| Automatic Transmission Pressure Regulating Valve 2 N216 | 12 | 52 |
| 3 | 1 | |
| Automatic Transmission Pressure Regulating Valve 3 N217 | 12 | 52 |
| 7 | 29 | |
| Automatic Transmission Pressure Regulating Valve 4 N218 | 12 | 52 |
| 11 | 4 |
Specified value: 1.5 Ω Max.
If the specified value 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 is found in the wiring and the resistance was not OK:
- Replace the faulty Solenoid Valve/Regulating Valve. Refer to , 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
- Check the DTC memory.
- If necessary, erase the DTC memory. Refer to Diagnostic Mode 04 - Reset/Delete Diagnostic Data .
- If the DTC memory was erased, generate readiness code. Refer to Readiness Code Description .
