STOREDCYLINDER 2 INJECTOR CIRCUIT
CC.1 : Short circuit to + 12 V
CO : Open circuit
CC : Short circuit
1.DEF : Injector control
NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the engine has been started.
Special notes:
If CC.1, CC, or 1.DEF is present, the level 2 warning light is lit.
If CO is present the level 1 warning light is lit.
If CO is still present, the OBD warning light will come on after three consecutive driving
cycles (starting + 5 seconds + switching off the ignition and waiting for 1 minute).
If the fault is present, the injection on cylinder 2 is disabled.
Use bornier Ele. 1681 or Ele. 1590 for any operation on the injection computer
connectors.
WARNING
This fault may appear if the wiring harness has been damaged.
Follow the procedure described in the Wiring Check in the Introduction.
This test enables the condition and the conformity of the engine wiring harness to be checked.

STOREDBATTERY VOLTAGE
1.DEF : Excess voltage
2.DEF : Undervoltage
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.
1.DEF
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,
–Check the continuity and absence of interference resistance of the following connections:
+ 12 V Supply relay track 5track M2 connector B of the engine management
computer
track 4 of Protection and Switching Unit
grey connectortrack G1 connector A of the engine management
computer
Battery earthtracks G4, H4, H1 injection computer connector A

STOREDCOMPUTER SUPPLY VOLTAGE
1.DEF : Voltage outside permitted range of values
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.
Carry out a road test followed by another check with the diagnostic tool.
