If failure “DF345 : Supply 5 volts potentiometers and sensor s” is
present or memori zed, it must be treated as most important .
Conditions for diagnostic appl ication at memorized failure:
Se t the contact on, then enter in dia logue with the computer
Or activation of the actua tor control “ AC 010 : Fuel pump relay”.
RECOMMEND ATIONS REMARK : This failure is most important. So it must be treated before
t he next ones.
* If the failure is memorized with OBD indicator on, check in the context
part, if state “ET241 : Fuel pump control cir cuit” corresponding to the
OBD indicator lighting request is affir mative. In this case , proceed as
per bellow mentioned method
