NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after a road test or an attempt to start the engine.
Special notes:
It is impossible to start the vehicle.
Use bornier Elé. 1681 for all operations on the injection computer connectors.
Check the UCH connections.
Check the injection computer connections.
Repair if necessary.
Test the multiplex network and carry out a complete fault finding procedure on the UCH.
Refer to the UCH Technical Note if a fault is declared present.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by a check with the diagnostic tool.

NOTES(Use the Wiring Diagrams Technical Note for the vehicle).
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:
