OR
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.

NOTESPriorities when dealing with a number of faults:
Deal with fault DF026 Front right wheel speed sensor circuit first if it is present.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present during a road test (in excess of 12 mph (20 km/h)
for 2 minutes).
Check the condition of the axle assemblies (impacts, damage, etc.) and the conformity and good condition of the
tyres.
Check that the braking system (condition of brake pads, sealing, sticking, bleed, bearing clearance, etc.) is in
good condition.
Visually inspect the condition of the target (for clogging, metallic contamination, bearing grease, etc.) and clean
using compressed air if necessary.
If there is a lot of grease on the target, contact the Techline.
Check that the wheel speed sensor mounting is in good condition.
Check the conformity of the target (condition, number of teeth = 48) using the special command SC001 Check
target teeth.
If there is non-conformity, replace the target.
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.
