Fault codes 16486 ... 16990

Note
The fault table is arranged according to the 5-digit fault code on the left.
♦
The SAE code which is displayed on the right next to the fault code (e.g.. P0107) can be ignored (at present only
♦
valid for USA).
Explanations regarding fault types (e.g. „open circuit or short-circuit to earth") µ Operating instructions for the ve-
♦
hicle system tester.
If parts are output as faulty: First check all cables and connectors to these components as well as the earth con-
♦
nections according to the Current Flow Diagram. Only if no fault is detected here should the part be replaced. This
applies in particular if faults are shown as „sporadic" (SP).
If „literature" appears in the display of the vehicle system tester -V.A.G 1552- look for the text required in the fault
♦
table under the fault code.
