NOTESPriority when dealing with a number of faults:
In the event of a combination of faults DF052 and DF026, DF027, DF028, and DF029,
the fault finding procedure remains the same in order to determine the faulty injector.
Special notes:
The engine stalls when the fault appears. The level 1 warning light illuminates along
with the message Faulty injection.
Switch off the ignition, check the condition and connection of the injector connectors.
Repair if necessary.
Switch off the ignition, disconnect the injectors (or the injector identified by DF026, DF027, DF028, DF029)
and switch the ignition back on.
Using the diagnostic tool, check for changes to DF052.
Is DF052 present or stored?
