NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present following a road test or after attempting to start the
engine.
Special notes:
Computer operating voltage: 9 V < PR071 < 16 V.
Battery voltage that is too low can cause the level 1 fault warning light to come on
thereby causing other faults to appear.
It is then not possible to start the engine.
Use bornier Elé.1681 or Elé.1590 for any operation on the injection computer
connectors.
Priorities when dealing with a number of faults:
If this fault is accompanied by DF226 Damper valve circuit 2.DEF: Fault external to
domain, ignore the latter fault as DF046 is the cause of this fault.
1.DEF
NOTESNone
Check the charge circuits:
Battery condition
Alternator condition (complete fault finding procedure)
Carry out the necessary repairs.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.
