NOTESConditions for applying the fault finding procedure to a stored fault:
the fault becomes present after:
– the ignition is switched on.
– the engine is started.
Special notes:
If the fault is present:
–the EOBD (European On Board Diagnostic) warning light is lit
–the level 2 warning light is lit for CC and 1.DEF,
–the level 1 warning light is lit for CO
Use bornier Elé. 1681 for all operations on the engine management computer
connectors.
After replacing an injector, run commands SC002 Enter injector codes (the IMA*
codes are read from left to right) and SC036 Reinitialise programming and follow the
procedure.
IMPORTANT:
– cylinder no.1 is located at the timing end.
– please observe the cleanliness guidelines and safety advice.
– do not disconnect the injectors with the engine running as this may damage the
engine
