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 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 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 to Transmission Control Module (TCM) 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.

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) --> [ Transmission Control Module, Replacing ] Transmission Control Module, Replacing.

Final Procedures

After the repair work, the following work steps must be performed in the following sequence:

1. Check the DTC memory. Refer to --> [ Diagnostic Mode 03 - Read DTC Memory ] Diagnostic Modes 01 - 09.

2. If necessary, erase the DTC memory. Refer to --> [ Diagnostic Mode 04 - Erase DTC Memory ] Diagnostic Modes 01 - 09.

3. If the DTC memory was erased, generate readiness code. Refer to --> [ Readiness Code ] Monitors, Trips, Drive Cycles and Readiness Codes.
