Fault finding – Fault Finding Chart
ALP1 No dialogue with engine management computer
Try to establish dialogue with a computer on another vehicle to make sure that the diagnostic tool is not faulty.
Check the battery voltage and make the necessary adjustments to obtain a correct voltage (9.5 V < Battery
voltage < 17.5 V).
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.
disconnect the engine management computer.
try to establish dialogue with another computer.
if the fault is still present, reconnect the computer and proceed by elimination by successively disconnecting all the
following computers (according to wiring diagram and equipment): air conditioning, airbag, abs and esp, uch,
instrument panel, central communication unit, proximity sensor.
Try to establish dialogue after disconnecting each line:
if, after a disconnection, you manage to establish dialogue, perform the fault finding procedure for the relevant
computer.
perform fault finding on the multiplex network using the diagnostic tool.
Check for the presence and the condition of the injection fuses on the UPC, and/or the engine fuse box.
check the connection of the computer connectors and the condition of its connections.
Check the injection computer earths (quality, oxidation, earth bolts secure on the battery terminal).
Check that the supply to the computer is correct:
Earth on tracks H1, G4 and H4 of black 32-track connector A.
+ after ignition feed on track D1 of black 32 track connector A.
Check that the power supply to the diagnostic socket is correct:
+ before ignition feed on track 16.
+ after ignition feed on track 1.
Earth on tracks 4 and 5.
If dialogue has still not been established after these checks, contact the techline.
