Working With Tester
- Use only Volkswagen Vehicle Diagnostic Testers.
The Guided Functions button and the Guided Fault Finding button offer various functions. The 3 most important functions are:
- Adapting installation information
- Reading measurements for mandatory reporting
- Performing basic measurement
Adapting Installation Information
The Mechatronic recognizes other control modules in the vehicle by signals from the Data bus. Pressing the Adapt Installation Information button tells the Mechatronic to forget all communication partners.
All active partners are recognized the next time the ignition is turned on.
Faults cannot be >>created<< with this function. Always use the Adapt Installation Information after the following tasks:
- After installing a gearshift mechanism.
- After a different control module is installed, for example, engine, ABS or Gateway.
- After working on the steering wheel paddle.
Reading Measurements for Mandatory Reporting
It is necessary to upload the measurements before contacting the Technical Service Center.
Save the measurements in the diagnostic log so that all the necessary transmission data is available for analyzing the faults.
Performing Basic Measurement.
This is how the Mechatronic learns the important settings. Also important adjustments are learned new or reset to the preprogrammed points. Among others, these are the synchronizing points and the corner points for the engaging lever and the gear selector.
Do not perform a basic measurement without cause or without being requested.
-- Press the J743 Perform Mechatronic Basic Measurement screen button only:
- If the "Guided Fault Finding" requests it
- After a fault stored in the Diagnostic Trouble Code (DTC) memory was corrected
- After a dual clutch was installed
- Or after a Mechatronic was installed
