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.

Check the charge circuits:
–Condition of the battery.
–Condition of the alternator (full fault finding procedure).
–Carry out the necessary repairs.
2.DEF

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,

NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after several starting attempts, or with the engine running.
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.
Use bornier Ele. 1681 or Ele. 1590 for any operation on the injection computer
connectors.
Check continuity and make sure there is no interference resistance on the following connection:
injection computer black 32-track connector A, track D1 track 1 UPC black connector
Repair if necessary.
Check fuse F5D (5A) located on the UPC.
Check the condition of the injection control unit supply relay (50A) located on the relay plate in the engine
connection unit under the Protection and Switching Unit (no false contacts, or oxidation on the relay mounting
clips).
Repair if necessary.
If the fault does not recur, start the engine and wait 1 min.
Carry out a road test and check the system faults.
If there are no faults, fault finding is complete.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.
