disconnecting the car's battery, always interrogate the fault memories. Investigate stored faults and, once any
faults have been remedied, cancel the fault memory.
-
Control unit plugs should only ever be connected and disconnected while the ignition is turned off.
-
The removal and installation of components, relays, fuses etc. can cause faults to be stored in fault memories
capable of self diagnosis. Always interrogate the fault memories after completing work on the electrical system.
