Self-diagnosis of the vehicle voltage control unit II

Fault table for the vehicle voltage control unit

Note
♦
All the possible faults which can be detected by the vehicle voltage control unit and can be displayed by
-V.A.G 1552- are listed below according to the 5-digit fault code.
♦
Before replacing components found to be defective first check the wiring and plug connections to these compo-
nents as well as the earth cables according to the current flow diagram.
♦
After repair always interrogate the fault memory using vehicle system tester -V.A.G 1552- and erase the memory.
♦
All static and sporadic faults are stored in the fault memory. A fault is detected as static if it exists for at least 2
seconds. If the fault is then no longer present, it is stored as a sporadic (temporary) fault. „/SP" appears on the right
of the display.
♦
After switching on the ignition, all the faults which exist are set to sporadic and are not stored as static faults unless
they continue to exist after completing the check.
♦
If a sporadic fault no longer occurs during 50 driving cycles (ignition on for at least 5 minutes, road speed > 30 km/
h), it is erased.
