INJECTOR CODE USE
NOTESOnly perform the tests if the statuses do not correspond with the system programming
functions.
YES
NO
Status ET104 is YES if the IMA option (individual injector correction) is activated in
the injection computer.
All the injectors have IMA codes etched on the bakelite body, but not all computers
use them.
In the case of a computer configured with the IMA option, the injector codes must be
entered into the injection computer in the following scenarios:
– when one or more injectors is replaced,
– when the injection computer is replaced,
– when the injection computer is reprogrammed.
If the injector codes are not programmed after these operations, fault DF276
Injector code programming will be present, and the engine will operate in defect
mode.
Run command SC002 Enter injector codes applying the procedure described in
the interpretation of this command.
Status ET104 is NO if the computer is not configured to interpret the IMA codes
(individual injector correction).
WARNING
A computer without the IMA option can be replaced by a computer with this option.
In this scenario status ET104 changes to YES after replacing the computer.
Fault DF276 Injector code programming will be present and the engine will operate
in defect mode.
In this case, run command SC002 Enter injector codes, applying the procedure
described in the interpretation of this command.
AFTER REPAIRCarry out a road test followed by another check with the diagnostic tool.

Run command SC002 Enter injector codes applying the procedure described in the
interpretation of this command.
If at the end of the procedure status ET104 remains FAULTY, contact the Techline.

RAIL PRESSURE
NOTESPerform this fault finding procedure:
– after the interpretation of fault DF053 Rail pressure regulation function,
– after an inconsistency for PR038 noted in the Parameters menu,
– after the interpretation of the fault finding procedure for AC011 Rail pressure
regulator,
– following a customer complaint (starting faults, poor performance, stalling, etc.).
Check the continuity and the absence of interference resistance on the following connections:
Injection computer, brown 48-track connector
B, track G3Track 2 of the rail pressure sensor connector
Injection computer brown 48-track
connector B, track A4Track 3 of the rail pressure sensor connector
Injection computer, brown 48-track connector
B, track C4Track 1 of the rail pressure sensor connector
If all these connections are correct, check for fuel pressure sensor power supply:
+ 5 V Track 3 of the rail pressure sensor connector
Earth Track 1 of the rail pressure sensor connector
Repair if necessary.
Check the sealing of the low and high-pressure diesel circuits (visual inspections, odour) pump housing,
overpressure valve, pipes, rail and injector unions, injector wells, etc.
If all of the previous checks are correct, switch the ignition on, wait for more than 1 minute and display PR038 Rail
pressure.
If the value is less than 50 bar, the rail pressure sensor is correct. If it is greater than this value, replace the rail
pressure sensor and tighten it to 35 ± 5 Nm.
AFTER REPAIRRepeat the conformity check from the start.

WRITE SAVED DATA
NOTESAll data must be backed up with command SC003 Backup computer data for this
command to be run.
Writing is carried out after the computer has been reprogrammed or replaced.
Confirming this command writes the data backed up using command SC003 Backup computer data.
The data is as follows:
– Vehicle-specific idle speed.
– Options available on the vehicle and managed by the computer (Example: Air conditioning).
– Injector calibration codes (if the vehicle is fitted with IMA).
– Programming of exhaust gas recirculation valve data.
They will configure the computer and will enable it to avoid:
– engine malfunction after reprogramming or replacing the computer,
– faulty interpretation of information provided by the CLIP tool.
AFTER REPAIRRestart the conformity check from the beginning.
