Valve Body Solenoid Valves, Checking

Diagnostic Procedures

Valve Body Solenoid Valves, Checking

Special tools, testers and auxiliary items required

• Multimeter (VAG1526) or multimeter (VAG1715)

• Connector test kit (VAG1594)

• Wiring diagram

Test requirements

• Respective fuses in fuse box (instrument panel, right) must be OK:

• Selector lever must be in P position.

• Ground (GND) connections to transmission must be OK.

• Ignition switched off.

Test sequence

- Disconnect 14-pin harness connector - arrow 2 - to solenoid valves (Solenoid Valve 1 (N88) to Solenoid Valve 6 (N93), Solenoid Valve 9 (N282), Solenoid Valve 10 (N283)).





Checking resistance

- Check resistances of solenoid valves at connector to the solenoid valves:









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

If one of the specified values is not obtained:

- Replace the respective solenoid valve.

- Erase DTC memory of Transmission Control Module (TCM) , Diagnostic mode 4: Reset/erase diagnostic data.

- Generate readiness code.

If specified values are obtained:

- Check wires according to wiring diagram.

Checking wiring

- Connect test box to control module wiring harness , connect test box for wiring test.

- Check wires between test box and 14-pin connector to Transmission Control Module (TCM) for open circuit according to wiring diagram.









- Also 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).
