Solenoid Valves In Valve Body, Checking
Solenoid Valves In Valve Body, Checking
Recommended Special Tools, Workshop Equipment, Testers, Measuring Instruments and Auxiliary Items
- V.A.G 1526 portable multimeter or V.A.G 1715 multimeter
- Adapter set V. A. G 1594
- Wiring diagram
Test Conditions
- Respective fuses must be OK
- Battery voltage must be at least 11.5 V.
- All electrical consumers such as, for example, lights and rear window defroster must be switched off.
- The parking brake must be applied, otherwise the daytime running lights are switched on.
- The Ground (GND) connections to transmission must be OK.
- Selector lever must be in "P" position.
- Ignition switched off.
Test Sequence
- Disconnect 14-pin connector - 2 -.
Observe safety precautions.
- Check harness connector for contact corrosion and ingress of water.
If harness connector is not OK:
- Repair the problem.
- Erase DTC memory of TCM. Diagnostic Mode 04 - Erase DTC Memory
- Generate readiness code. Generate Readiness Code
If harness connector is OK:
- Check resistance of solenoid valves.
Checking Resistance of Solenoid Valves
- Check resistances of solenoid valves at connector to solenoid valves:
NOTE: Resistance value is valid at approx. 20 degrees C. At higher temperatures, resistance values increase.
If one of the specified values is not attained:
- Replace corresponding solenoid valve.
- Erase DTC memory of TCM. Diagnostic Mode 04 - Erase DTC Memory
- Generate readiness code. Generate Readiness Code
If the specified values are achieved:
- Check wiring to TCM according to wiring diagram.
Wiring to TCM, Checking
- Connect test box to control module wiring harness. Test Box, Connecting For Wiring Test
- Check wires between test box and 14-pin connector to Transmission Control Module (TCM) for open circuit according to wiring diagram.
Wiring resistance: max. 1.5 Ohms
- Also check wires for short circuit to each other.
Specification: Infinite Ohms.
If no fault is detected in the wiring:
- Replace Transmission Control Module (TCM) -J217-.
