NOTE: Sensor is located inside the transmission and is not accessible from the outside.

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

Requirements
- Respective fuses must be OK.
- Selector lever must be in -P- position.
- All electrical consumers such as, lights and rear window defroster must be switched off.
- Parking brake must be engaged.
- Ground (GND) connections to transmission must be OK.
- Ignition switched off.

Test sequence







- Disconnect 20-pin harness connector -2-.
Observe safety precautions.

- Check harness connector for contact corrosion and ingress of water.

If harness connector is not OK:
- Repair the malfunction.
- Erase DTC memory of Transmission Control Module (TCM), Diagnostic mode 4: Reset/erase diagnostic data. Diagnostic Mode 4: Reset/Erase Diagnostic Data
- Generate readiness code. Monitors, Trips, Drive Cycles and Readiness Codes

If harness connector is OK.
- Check wires to Transmission Control Module (TCM) according to wiring diagram.

Checking wires to Transmission Control Module (TCM)
- Connect test box to control module wiring harness. Test Box, Connecting For Wiring Test







- Check for open circuits in wires between test box and 20-pin harness connector to Transmission Control Module (TCM) according to wiring diagram.

Terminal 3 + socket 28
Terminal 4 + socket 29

Wire resistance: max. 1.5 Ohms

- Check wires for short circuit to each other, to vehicle Ground (GND) and to B+.
Specified value: Infinite Ohms

If no malfunctions are found in wires:
- Check resistance of Intermediate Shaft Speed Sensor -G265-.

Check sensor resistance
- Re-connect 20-pin connector.
- Check sensor resistance between test box sockets 28 + 29.
Specified value: 400 to 600 Ohms

- Check wires between test box sockets for short circuit to Ground (GND) and short circuit to B+ according to wiring diagram:

Socket 1 + 28
Socket 1 + 29
Socket 28 + 68
Socket 29 + 68

Specified value: Infinite Ohms

If specified values are obtained:
- Replace Transmission Control Module (TCM) -J217-.

If specified values are not obtained.
- Check internal wire in valve body:

If no malfunctions are found in the internal wires.
- Replace Intermediate Shaft Speed Sensor -G265-.
- Erase DTC memory of Transmission Control Module (TCM), Diagnostic mode 4: Reset/erase diagnostic data. Diagnostic Mode 4: Reset/Erase Diagnostic Data
- Generate readiness code. Monitors, Trips, Drive Cycles and Readiness Codes
