Volkswagen Tiguan Service and Repair Manual: Generator

General Information

Note

Check the generator. Refer to Wiring Diagrams, Fault Finding Electrical Systems and Installed Locations.

Generator on A Vehicle with the Start/Stop System:

Up to now, the generator and the voltage regulator were connect to the engine- and vehicle electrical system control module by a single cable. If the vehicle has the Start/Stop System, the information is transmitted to the data bus diagnosis interface via the LIN data bus. The data bus diagnosis interface then sends the information to the other control modules, such as the engine control module, via the CAN data bus.

B+ Wire, Securing on Generator

Caution

If the B+ wire is not tightened to the specification, the following risks may occur:

  • The battery is not completely charged.
  • The complete vehicle electrical system systems/electronics may fail (disabled vehicle).
  • Fire hazard due to sparking.
  • Damage to electronic components and control modules caused by excessive voltage.

Tighten the nut on the B+ wire -arrow- to 15 Nm.
