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.
