The following will aid in the diagnosis of which of the high pressure fuel pumps is noisy.

16

NOTE: carry out the diagnostic routine on a cold engine (less than 95°F / 35°C) at idle speed
with the hood open.
Carry out the following routine while listening for the suspected fuel pump noise. As the fuel pumps are
deactivated in turn, it should be possible to determine which pump is noisy as the metallic 'clicking'/
'rasping' noise will stop when that fuel pump is no longer running. Replace only a noisy pump; if no
difference can be determined from either pump during the routine, further diagnostics will be required into
the source of the noise. In the unlikely event that both pumps are suspected to be noisy, contact the
Technical Helpline for further advice.

&
cAUTION: a Jaguar Land Rover-approved Midtronics battery power supply must be connected to
the vehicle battery during SDD diagnosis/ module programming.

! CAUTION: ensure all ignition ON/OFF requests are carried out; failure to perform these steps may
cause damage to control modules in the vehicle.

NOTE: the Jaguar Land Rover-approved diagnostic tool must be loaded with DVD144.01 v.225 or
later.

NOTE: the primary function of the following routine is to assist in determining pump performance.
In this bulletin the test is being utilized for an audible fault. The test will conclude with a pass or fail. if
the test concludes with a pass, this does not indicate the pump is not causing an audible fault.
