WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2003 Volkswagen EuroVan, 2002 Volkswagen EuroVan, 2001 Volkswagen EuroVan, 2000 Volkswagen EuroVan, and 1999 Volkswagen EuroVan. However, it is still accessible from the selected car via links, so may be relevant.
- Cruise control system
- Ignition timing influences
Not only the engine control module, but also other control modules exchange information via the data bus - as in this example.
If the automatic transmission control module detects that signals are missing or faulty, the data bus itself, another system or a component of another system may be defective.
