The troubleshooting is intended specially for testing using the HHT.

Cables, connectors and fuses are also taken into account in the following tests.

If modifications/manipulations or improper repairs have been performed by third parties (e.g. driver, customer), the following test program can only be used to a limited extent. This also applies to the wiring diagram.
