Fault table
Notes:
-
◆ The fault table is listed according to the 5 digit fault code on the left.
-
◆ Explanation of the fault types (e.g. "open circuit/short circuit to earth"):
=> Fault reader operating instructions
-
◆ Before renewing components indicated as being faulty, check the wiring and connectors to these components as well as the earth connections using current flow diagram. This is particularly relevant if faults are output as "occurring sporadically" (SP).
