Tool
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.

ALP1 No dialogue with the computer
NOTESOnly consult this customer complaint after a complete check with the diagnostic
tool.
Try to establish dialogue with a computer on another vehicle to check that the diagnostic tool is not faulty. If the
tool is not at fault, and dialogue cannot be established with any other computer on the same vehicle, the cause
could be a faulty computer interfering on the multiplex network. Check the battery voltage and make the necessary
adjustments to obtain a correct voltage (9.5 V < Battery voltage < 17.5 V).
Carry out fault finding on the multiplex network using the diagnostic tool (see88B, Multiplexing).
Check the presence and the condition of the injection fuses in the engine fuse box.
Check the connection of the injection computer connectors, component code 120 and the condition of its
connections.
Check the injection computer earths (quality, oxidation, tightness of earth bolts on the battery terminal).
Check that the supply to the computer is correct:
●NH or N between the earth and component 120.
●AP29 or AP15 between components 1016 or 260 and 120.
If the connection or connections are faulty and if there is a repair procedure (see Technical Note 6015A (Renault)
or Technical Note 9804A (Dacia), Electrical wiring repair, Wiring: Precautions for repair), repair the wiring,
otherwise replace it.

Ensure that the diagnostic socket, component code 225, has properly power supply:
●+ Before ignition feed on connection BP56 or BP10 of component 225.
●+ After ignition feed on connection AP10 of component 225.
●Earth on connections MAM and NC or MK and NA of component 225.
If the connection or connections are faulty and if there is a repair procedure (see Technical Note 6015A (Renault)
or Technical Note 9804A (Dacia), Electrical wiring repair, Wiring: Precautions for repair), repair the wiring,
otherwise replace it.
