NOTESSpecial notes:
The fault is declared present during a road test at a speed of > 6 mph (10 km/h). The
computer signals an external supply fault.
Conditions for applying the fault finding procedure to stored faults:
Apply the fault finding procedure whether the fault is present or stored.
Check the connections and the condition of the battery terminals.
Check the condition and position of the ABS fuses in the engine fuse and relay box.
Check the 50A power fuse in position 5 on the power fuse board.
Check the 25A fuse F13 on the UPC and the correct locking of the grey 4-track PPHI connector (Vdiag 44) or
the 25A fuse F8 on the UPC and the correct locking of the black 6-track CM connector (Vdiag 48).
Check the connection and condition of the tab 1 red wire of the grey connector.
Check the connections on the 26-track connector of the ABS computer.
Check the ABS earths on tracks 1 and 4 (attached under the ABS unit) and carry out an inspection of the entire
ABS wiring.
Check the continuity between the fuses and tracks 2 and 3 of the computer connector (+ Before ignition present
on the tracks) and between the UCH and track 18 of the computer (+ After ignition present on the track).
Clear the computer fault memory. Switch off the ignition.
Switch on the ignition again and carry out another check 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.

Carry out a road test followed by another check with the diagnostic tool.
If the fault initially declared DF006 "Front left-hand wheel speed sensor circuit" becomes DF026 "Front
right-hand wheel speed sensor circuit", replace the wheel speed sensor.
If the fault remains on the same side, the wiring between the computer and the sensor is faulty.
Check the connection and the condition of the computer connectors. Repair if necessary.
Check and ensure the continuity of the following connections:
Sensor connector one of the 2 tracks Track 5 computer connector
Sensor connector the other track Track 16 computer connector
Also check the insulation between these two connections.

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 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.
If the checks are correct:
–the computer fault memory has been cleared,
–exit fault finding mode, switch off the ignition and carry out a road test.
Replace the instrumented bearing if the fault recurs.
