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 < operating voltage < 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 Ele. 1681 or Ele. 1590 for any operation on the injection computer
connectors.

NOTESNone
Check the charge circuits:
–Condition of the battery.
–Condition of the alternator (full fault finding procedure).
–Carry out the necessary repairs.
2.DEF
NOTESNone
With the ignition off, measure the voltage across the battery terminals.
If the voltage is less than 11.5 V, test the battery.
If the battery is faulty, replace the battery then test the charge circuit.
With the ignition on and the with the starter motor turning, measure the voltage between the battery terminals
If the voltage drops below 9.6 V, check the tightness and condition of the battery terminals.
Repair if necessary.
If the terminals are in good condition, test the battery.
If they are faulty, replace the battery.
If the starter is cranking the engine correctly, but the fault is still present,
