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 if they are stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after a road test at a speed of over 36 mph (60 km/h) on
a winding road.
Check the condition of the axles (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 the quality of the mounting of the wheel speed sensors (correct clipping without excessive play).
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) of the R2 black 52-track
intermediate connection under the front left 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.

1.DEF : Carry out the multiplex network fault finding procedure
NOTESSpecial notes:
Although stored in the computer, the fault is not due to ABS components but injection
components. Run fault finding on the injection system.
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.
The multiplex injection signal is sent to the ABS system 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 on the UPC (Vdiag 44) or the grey CT1
connector of the UPC (Vdiag 48).
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.

NOTESSpecial notes:
If several computers are affected by a similar multiplex network fault, contact the
Techline to check the cases previously noted first.
Conditions for applying the fault finding procedure to stored faults:
Apply the fault finding procedure as below.
If no other computer has detected a multiplex network fault but only the absence of ABS frames, carry out the
following checks:
–check the connection and condition (corrosion, bent terminal, crimping, etc.) of the computer connections
(tracks 15 and 26). Repair if necessary.
Check the connection (locking) and condition (corrosion, bent terminals, crimping, etc.) of the blue PEH connector
on the UPC (Vdiag 44) or the grey CT1 connector of the UPC (Vdiag 48).
Repair if necessary.
Check the insulation, continuity and absence of interference resistance between:
Computer connector track 15 Track 7 of the blue PEH connector of the Vdiag 44 UPC
Track 2 of the grey CT1 connector of the Vdiag 48 UPC
Computer connector track 26 Track 11 of the blue PEH connector of the Vdiag 44 UPC
Track 3 of the blue CT1 connector of the Vdiag 48 UPC
Also check the insulation between these two connections. Repair or replace the wiring if necessary.
If the problem is still present, run fault finding on the multiplex network.
AFTER REPAIRClear the computer fault memory.
