Valve Body Solenoid Valves, Checking

Valve Body Solenoid Valves, Checking

Special tools, testers and auxiliary items required

• Multimeter (VAG1526) or Multimeter (VAG1715)

• Connector test kit (VAG1594)

• Wiring diagram

Test Prerequisites

• 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 04 - Erase DTC Memory ] Diagnostic Mode 04 - Erase DTC Memory.

- Generate readiness code => [ Readiness Code ] Monitors, Trips, Drive Cycles and Readiness Codes.

If specified values are obtained:

- Check wires according to wiring diagram.

Wiring, Checking

- 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.

Wire resistance: max. 1.5ohms









- Also check wires for short circuit to each other.

Specified value: infinit ohms

If no malfunctions are found in wires:

- Replace Transmission Control Module (TCM) (J217) => [ Transmission Control Module, Replacing ] Transmission Control Module, Replacing.
