STOREDINJECTION MULTIPLEX SIGNAL ABSENT
NOTESSpecial notes:
Even though it is stored in the computer, this fault does not cause the warning light to
come on or a fault message, because the ABS system is not faulty.
Perform fault finding on the injection system using the diagnostic tool.
Note:
The injection computer does not always store these transient faults as quickly as the
ABS computer.
If no fault is stored in the injection computer, start the engine; if there is no fault
present, contact the Techline. After solving the injection system problem, erase
the faults from the ABS computer memory.
Priority in the event of a number of faults:
Deal with fault DF152 Multiplex network first if it is present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present when the engine is started up.
Perform a multiplex network test and an injection check (see MR413 Fault finding, 13B, Diesel injection or 17B,
Petrol injection) using the diagnostic tool.
If the fault is still present, contact the Techline.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.

Conditions for applying the fault finding procedure to stored faults:
The fault is declared present during a road test.
Carry out fault finding on the injection system (see MR413 Fault Finding, 13B, Diesel injection or 17B,
Petrol injection).
If the fault is still present, contact the Techline.
AFTER REPAIRClear the computer fault memory.

Fault finding - Fault Finding Chart
ALP 1 No dialogue with the ABS computer
NOTESOnly consult this customer complaint after a complete check with the diagnostic tool.
Check that the diagnostic tool is not causing the fault by trying to establish dialogue with a computer on another
vehicle. 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 carry out the necessary operations to obtain the correct voltage (9.5 V < Battery
voltage < 17.5 V, see MR411 Mechanical systems, 16A, Starting-charging).
Run fault finding on the multiplex network, using the diagnostic tool (see MR413 Fault finding, 88B, Multiplex).
Check the condition and position of the 15A and 20A fuses in the engine fuse and relay box.
Check the condition and position of the F10 5 A fuse in the Passenger compartment fuse box.
Consult section 81C, Fuses.
Check the connection and condition (possible damage to the wiring) of the connector of component 1094.
If the connector is faulty (see Technical Note 6015A, Repairing electrical wiring, wiring: Precautions for
repair), repair the connector, otherwise replace the wiring.
Check that the supply to the computer is correct:
●Connector of component 1094 disconnected, check the insulation and continuity of connection MAH
of component 1094 (tightness, oxidisation etc.).
●Connectors of component 1094 and R107 disconnected, check the insulation and continuity of
connection AP5 between component 1094 and intermediate connector R107.
●Check the insulation and continuity of connection AP5 between intermediate connector R107 and
component 1016.
●Connectors of component 1094 and R67 disconnected, check the insulation and continuity of
connections BP8 and BP14 between component 1094 and intermediate connector R67.
●Check the insulation and continuity of connections BP8 and BP14 between intermediate connector R67
and component 597.
If the connection or connections are faulty (see Technical Note 6015A, Electrical wiring repair, Wiring:
Precautions for repair), repair the connectors or wiring, otherwise replace the wiring.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.
