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.

NOTESOnly consult this customer complaint after a complete check with the diagnostic tool.
Air transit from the hydraulic unit regulation channels to the brake circuits.
Bleed the circuits, following the procedure using the diagnostic tool commands (see Command mode
procedures).
Following the operation, carry out a road test with ABS regulation.
If the fault is still present, carry out the above operation again 1 or 2 times.
If the customer complaint is particularly pronounced, and the bleeding procedures have not rectified it, contact the
Techline.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.
