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).
