STOREDWHEEL SPEED CONSISTENCY
CC.1 : short circuit to + 12 V
1.DEF : interference
NOTESSpecial notes:
This fault indicates that the wheel speeds are inconsistent with each other. The
computer does not know how to determine which one is faulty.
Priorities when dealing with a number of faults:
Deal with faults DF006, DF007, DF026 and DF027 first, even when stored.
Conditions for applying the fault finding procedure to stored faults:
The fault appears after a road test at a speed of > 36 mph (60 km/h) on a winding road.
Check the condition of the axle assemblies (impacts, damage, etc.) and the conformity and good condition of the
tyres.
Ensure that the braking system is in good condition (condition of the linings, tightness, grip, bleeding, bearing play,
lubricant on the targets, etc.).
Check that the wheel speed sensor mountings are in good condition.
Check the sensor/target air gap over one wheel revolution: 0.1 mm < wheel air gap < 1.2 mm.
Check the conformity of the target (condition, number of teeth = 48) using the specific command SC001 Check
target teeth.
Repair if necessary.
Carry out a visual check on the connection and condition of the sensor and computer connectors Check the
connection and condition of the connections (tracks 31, 32, 33 and 34) on the 52-track intermediate black
connection R2 under the front left-hand seat. Repair if necessary.
If all the checks are correct, clear the computer's fault memory.
Exit the fault finding procedure and carry out a road test. 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.

STOREDINJECTION MULTIPLEX SIGNAL ABSENT
NOTESSpecial notes:
Although the fault is stored in the computer, it is not caused by ABS/ESP components,
but it indicates that the ESP is deactivated due to an injection frame transmission fault.
Run fault finding on the injection system.
Note:
The injection does not always store these transient faults as quickly as the ABS/ESP
system. If no fault is stored in the injection computer, start the engine; if there is no fault
present, contact the Techline.
Once the fault in the injection system has been repaired, clear the ABS/ESP computer
fault memory.
The injection multiplex signal is transmitted to the ABS/ESP computer via the
Protection and Switching Unit.
Priorities when dealing with a number of faults:
Deal with faults DF152 and DF153 first, whether they are present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present when the engine is started up.
Check the condition and correct locking of the blue PEH connector of the UPC (Vdiag 44) or the grey CT1
connector of the UPC (Vdiag 48 or higher).
Carry out a multiplex network test and check the injection system with 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.

FRONT RIGHT-HAND WHEEL TARGET
NOTESSpecial notes:
This fault means that some magnetic poles of the target are not detected by the sensor.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present following a road test at a speed of > 36 mph (60 km/h).
Check for play in the bearing.
Visually inspect the condition of the target and sensor (for dirt, 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 the quality of the mounting of the wheel speed sensor (correct clipping without excessive play).
Check the sensor/target air gap over one wheel revolution: 0.1 mm < front wheel air gap < 1.2 mm.
Check the conformity of the target (condition, number of teeth = 48) using the specific command SC001 Check
target teeth.
Replace the instrumented bearing if the number of teeth is incorrect.
If all the checks are correct, reconnect the computer and the wheel speed sensor.
Clear the computer fault memory.
Exit fault finding mode, switch off the ignition and carry out a road test.
If the fault is still present, contact the Techline.
AFTER REPAIRClear the computer fault memory.
