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 is lit.
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.
Perform a multiplex network test and run complete fault finding on the UCH (see 87B, Passenger compartment
connection unit) if the 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 another check with the diagnostic tool.
