Fault table
Fault table
  Note
t  The fault table is ordered according to the 5-digit fault code on the left.
t  Explanations on fault types (e.g. “open circuit/short-circuit to earth”): → Operating instructions of vehicle system tester.
t  If parts are output as faulty: First test all of the cables and plug connections to these components as well as the earth cables of the system according to the current flow diagram. Replace component only if these tests do not reveal any fault. This applies in particular if the fault is shown as sporadic (SP).
