Solenoid Valves In Valve Body, Checking
Solenoid Valves In Valve Body, Checking
Recommended special tools and equipment
- VA.G 1526 multimeter or V.A.G 1715 multimeter
- V.A.G 1594 connector test kit
- Wiring diagram
Test requirements
- Respective fuses must be OK.
- Battery voltage must be at least 11.5 volts.
- All electrical consumers such as: lights and rear window defroster must be switched off.
- Parking brake must be engaged or else day time driving lights will be switched on.
- Ground (GND) connections to transmission must be OK.
- Selector lever must be in -P- position.
- Ignition switched off.
Test sequence (vehicles with 01M transmission)
- Disconnect 12-pin harness connector at transmission.
Observe safety precautions.
- Check harness connector for contact corrosion and ingress of water.
If harness connector is not OK:
- Repair the malfunction.
- Erase DTC memory of Transmission Control Module (TCM).
- Generate readiness code.
If harness connector is OK:
- Check resistance of solenoid valves.
Checking resistance of solenoid valves
- Re-connect 12-pin connector.
- Connect test box to control module wiring harness.
- Measure resistance of solenoid valves at test box between sockets:
NOTE: Resistance value is valid at approx. 20 degrees C. At higher temperatures, resistance value increases.
If one of the specified values is not obtained:
- Check wires to Transmission Control Module (TCM) according to wiring diagram.
Checking wires to Transmission Control Module (TCM)
- Disconnect 12-pin harness connector at transmission.
- Check wires between test box and 12-pin connector to Transmission Control Module (TCM) for open circuit according to wiring diagram.
Wire resistance: max. 1.5 Ohms
- Check wires for short circuit to each other.
Specified value: Infinite Ohms
If no malfunctions are found in wires:
- Replace circuit board or valve body.
- Erase DTC memory of Transmission Control Module (TCM).
- Generate readiness code.
Test sequence (Vehicles with 09G transmission)
- Disconnect 14-pin harness connector -2-.
Observe safety precautions.
- Check harness connector for contact corrosion and ingress of water.
If harness connector is not OK:
- Repair the malfunction.
- Erase DTC memory of Transmission Control Module (TCM).
- Generate readiness code.
If harness connector is OK:
- Check resistance of solenoid valves.
Checking resistance of solenoid valves
- Check resistances of solenoid valves at connector to the solenoid valves:
NOTE: Resistance value is valid at approx. 20 degrees C. At higher temperatures, resistance value increases.
If one of the specified values is not obtained:
- Replace respective solenoid valve.
- Erase DTC memory of Transmission Control Module (TCM).
- Generate readiness code.
If specified values are obtained:
- Check wires to Transmission Control Module (TCM) according to wiring diagram.
Checking wires to Transmission Control Module (TCM)
- Connect test box to control module wiring harness.
- Check wires between test box and 14-pin connector to Transmission Control Module (TCM) for open circuit according to wiring diagram.
Wire resistance: max. 1.5 Ohms
- Check wires for short circuit to each other.
Specified value: Infinite Ohms
If no malfunctions are found in wires:
- Replace Transmission Control Module (TCM) -J217-.
