commandDiagnostic tool title Comments
AC029 High pressure circuit sealing testActivating this will request the injection system to detect a
leak on the high pressure circuit after a procedure has been
carried out. This is activated with the engine warm and
running and consists of unladen acceleration repeated 4
times.
AC056 Power-assisted steering
assembly relayActivating this actuates the power assisted steering pump.
AC060 Preheating warning lightActivating this actuates the preheating warning light on the
instrument panel.
AC061 Overheating warning light.Activating this actuates the engine overheating warning light
on the instrument panel.
AC068Injection fault warning light.Activating this actuates the injection fault warning light on
the instrument panel.
AC099Deactivation of electrical
consumersThis activation only deactivates the preheating function.
AC100End deactivation of electrical
consumersActivating this enables preheating to be authorised after the
injection computer has been programmed or reprogrammed
(see Replacement of components).
AC153 High-speed fan assemblyActivating this actuates the high speed fan relay to test the
supply to the high speed fan.
AC154 Fan low speed.Activating this actuates the low speed fan relay to test the
supply to the low speed fan.
AC155MIL warning lightThis activation controls the malfunction indicator light on the
instrument panel (emission control/EOBD warning light).
AC180 Air conditioning compressor
relay control.Activating this enables you to listen to the operation of the
air conditioning compressor.
AC212 New pump chamber fillingThis must only be activated after the high pressure pump
has been replaced (see Replacement of components).
This command is used to activate the pump repriming
sequence.
AC250 Heating resistor 1 relay.Activating this controls the heating resistor no. 1 relay to test
the heating resistor supply.

Is the timing set correctly? Carry out the necessary repairs.
Visually check the condition of the engine wiring harness.
Does the starter motor operate correctly (minimum engine
speed = 200 rpm)?Carry out the necessary repairs.
Is the compression in order? Carry out the necessary repairs.
Using the diagnostic tool, check that the injector codes (C2I) are correctly entered on the identification screen.
If not, configure the correct injector codes using command SC002 Enter injector codes

NOTESOnly address this customer complaint after a complete check with the diagnostic
tool.
Check that there are no obstacles that might impede the accelerator pedal travel (carpet, hard point, etc.).
Using the diagnostic tool, check that the injector codes (C2I) are correctly entered on the identification screen. If
not, configure the correct injector codes using command SC002 Enter injector codes
Visually check the condition of the engine wiring harness.
Is the clutch clearance set correctly?Carry out the necessary
repairs.
Check that the engine has not sucked up its oil (engine racing).
Check that the turbocharger is working properly.
Run TEST 11 Air line at the turbocharger.

When all the preparations are complete, start the engine and leave it running:
For 30 seconds at idle speed for Euro 4 type engines: K9K 714 - 718 - 740 - 792 - 796.
Let it idle for 2 minutesfor the euro 3 type engines: K9K 790 - 794.
Note:
These time periods must be respected for the test results to be interpreted correctly.
–Run command AC029 High pressure circuit sealing check
.The engine will automatically carry out a cycle of four accelerations to increase the rail pressure and measure
the internal injector leaks under these conditions.
–When the cycle has finished, run command AC029 High pressure circuit sealing test a second time to
obtain the correct return volume reading for each injector.
Switch off the engine at the end of the cycle.

If the engine does not start, only the static leakage can be measured, i.e. the leakage with the injector closed, not
actuated and under high pressure.
Make sure that the ignition circuit is working correctly (minimum engine speed 200 rpm).
Tooling required
–Mot. 1711 Injector flow measuring kit.
Or: Use 4 pipes with internal diameter 4mm and approximately 50 cm in length, and a test adapter (TEST
IMV).
Procedure
– Switch off the ignition,
– disconnect the return pipes from the four injectors,
– cap the pump venturi tube to prevent the low-pressure circuit from depriming,
– connect the four transparent pipes in place of the return pipes (Mot. 1711),
– disconnect the low pressure actuator from the pump (brown IMV connector) and connect a test IMV or the Mot.
1711,
– electrically disconnect the four injectors,
– switch on the ignition and engage the starter for 5 seconds,
– measure the amount of diesel fuel in each pipe.
If the return leakage is greater than 10 cm, replace the injector(s) (see MR 388 (Logan/Sandero) or MR 451
(Duster), MR 423 (Thalia 2/Symbol 2) or MR 374 (Kangoo VLL), Mechanical, 13B, Diesel injection, Diesel
injector: Removal - Refitting).
Switch off the ignition, and reconnect the four injectors electrically.
Disconnect the test low pressure actuator and reconnect the low pressure actuator connector to the pump.
Disconnect the four transparent tubes and reconnect the injectors return circuit. Switch on the ignition again, and
clear the injection faults using the diagnostic tool.
