- Switch off ignition.
- Separate plug connection at transmission.
- Measure voltage in transmission wiring harness using a multimeter.
- Switch on ignition.
Measure direct voltage with multimeter between 5 and 4Specified value
- Voltage [8,5...16,4] V
Question
- Is the measurement value OK?
YES
The measurement value is OK.Further causes

Test K cable to control unit Y3/8n4 (Fully integrated transmission control (VGS) control unit).
Operation number of operation texts and work units or standard texts and flat rates:27-0641Test prerequisite
- The power supply of component Y3/8n4 (Fully integrated transmission control (VGS) control unit) is OK.
Test sequence
- Switch on ignition.
- Test voltage at component X11/4 (Diagnosis test connector).
- If several control modules are connected to a K-wire, the voltage can be measured even if an open circuit exists.
