NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after an attempt to start engine.
Special notes:
It is impossible to start the vehicle.
If the fault is present, the level 2 warning light will light up.
Use bornier Ele. 1681 or Ele. 1590 for any operation on the injection computer
connectors.
Check the UCH connections.
Check the injection computer connections.
Repair if necessary.
Test the multiplex network (see 38B, Multiplexing) and carry out a complete fault finding on the UCH.
Refer to the UCH Technical Note (see 87B, Passenger compartment connection unit) if the fault is displayed
as present.
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.

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after one attempt to start the engine, or with the engine
running.
Special notes:
If 6.DEF, 8.DEF or 12.DEF are present the level 1 warning light is lit.
If one of the other faults is present, the level 2 warning light comes on.
If 6.DEF 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).
Use bornier Ele. 1681 or Ele. 1590 for any operation on the injection computer
connectors.
Priority when dealing with a number of faults:
Deal with fault DF046 Battery voltage first if it is present or stored.
1.DEF to 5.DEF
7.DEF, 8.DEF
10.DEF
12.DEF to 14.DEFCheck the injection computer connections and the continuity of all the supplies.
Repair if necessary.
Clear the faults.
Switch off the ignition, wait 1 minute and switch the ignition on again.
If the fault is still present, contact the Techline and complete the fault finding log.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.
