Solenoid Valves In Valve Body, Checking

Solenoid valves in valve body, checking

Recommended special tools and equipment
- V.A.G 1526 multimeter or V.A.G 1715 multimeter
- V.A.G 1594 connector test kit
- Wiring diagram

Test requirements
- Selector lever must be in -P- position.
- Ground (GND) connections to transmission must be OK.
- Ignition switched off.

Test sequence

- Connect test box to control module wiring harness.

Checking resistance

- Measure resistance of solenoid valves at test box between sockets:






Note: Resistance value is valid at approx. 20°C. At higher temperatures, resistance value increases.

If one of the specified values is not obtained:
- Check wires according to wiring diagram.

Checking wiring
- 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 relevant solenoid valve.

- Erase DTC memory of Transmission Control Module (TCM).
- Generate readiness code.
