Injector fault
Check the injector and surrounding area for evidence of fuel
leakage. Disconnect the injector and check for evidence of fuel
leakage in the connector. Rectify as necessary. Clear the DTCs.
Reconnect the injector and start the engine. Allow to warm up
and allow to idle (cylinder balance diagnosis is now active). If the
DTC resets, check for blow-by etc. and rectify as necessary. Clear
the DTCs and recheck. Carry out a compression test only if the
DTC resets. If the above tests are all within range, install a new
injector.

1. WARNINGS:
Do not carry out any repairs to the fuel system with the
engine running. The fuel pressure within the system can be as
high as 1700 bar (24,656 lb-sq-in). Failure to follow this
instruction may result in personal injury.
Do not smoke or carry lighted tobacco or open flame of
any type when working on or near any fuel related
components. Highly flammable vapors are always present and
may ignite. Failure to follow these instructions may result in
personal injury.
If fuel contacts the eyes, flush the eyes with cold water
or eyewash solution and seek immediate medical attention.
Place the vehicle in a well ventilated, quarantined area
and arrange ' No Smoking/Petrol Fumes' signs about the
vehicle.
Wait at least 30 seconds after the engine stops before
commencing any repair to the high-pressure fuel injection
system. Failure to follow this instruction may result in personal
injury.
Wash hands thoroughly after fuel handling, as prolonged
contact may cause irritation. Should irritation develop, seek
medical attention.
Do not carry or operate cellular phones when working on
or near any fuel related components. Highly flammable vapors
are always present and may ignite. Failure to follow these
instructions may result in personal injury.
• CAUTIONS:
Before using the cleaning fluid, protect all electrical
components and connectors with lint-free non-flocking material.
Make sure that all parts removed from the vehicle are
placed on the lint-free non-flocking material.
Make sure that any protective clothing worn is clean and
made from lint-free non-flocking material.
Make sure that clean non-plated tools are used. Clean
tools using a new brush that will not lose its bristles and fresh
cleaning fluid, prior to starting work on the vehicle.
Use a steel topped workbench and cover it with clean,
lint-free non-flocking material.
Make sure the workshop area in which the vehicle is being
worked on is as clean and as dust free as possible. Foreign
matter from work on clutches, brakes or from machining or
welding operations can contaminate the fuel system and may
result in later malfunction.
Using a new brush that will not lose its bristles, brush
cleaning fluid onto the components being removed and onto
the surrounding area.
2. Using a pneumatic vacuum gun, remove all traces of cleaning
fluid and foreign material.
3. Dispose of any used cleaning fluid and the brush after
completing the repair.
