NOTESPriorities when dealing with a number of faults:
Deal with fault DF006 Front left 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.
Visually inspect the condition of the axle assemblies (impacts, deformations etc.) and the conformity and good
condition of the tyre mountings (see MR 411, Mechanical systems, 35A, Wheels and tyres, Tyres,
Identification and Tyre pressure, Identification).
Replace the tyre(s) if necessary (see MR 411, Mechanical, 35A, Wheels and tyres, Tyres, Removal - Refitting).
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.
Check that the wheel speed sensor mounting is in good condition.
Check the sensor/target air gap through one wheel revolution (0.4 < front wheel air gap < 1.7 mm).
If the air gap is incorrect:
–Replace the instrumented bearing/wheel sensor mounting assembly if necessary (see MR 411, Mechanical,
31A, Front axle components, Hub carrier bearing: Removal - Refitting).
If the air gap is correct.
–Swap both front wheel speed sensors.
–Clear the computer fault memory.
–Carry out a road test followed by another check with the diagnostic tool.
–If the fault initially declared as DF091 has become DF090 Front right-hand wheel target, replace the magnetic
target (see MR 411, Mechanical, 31A, Front axle components, Front hub carrier bearing: Removal –
Refitting).
–If the fault remains on the same side, replace component 153 (see MR 411, Mechanical, 38C, Anti-lock
braking system, Front wheel speed sensor, Removal - Refitting).

If the fault appears while the vehicle is being driven on a steep gradient, during a very
tight turn or while the vehicle is being transported on a lorry, train, boat etc., with the
engine running, clear the fault and test drive, if possible, to check that the fault does
not return.
Conditions for applying fault finding procedures to stored faults:
The fault is declared present after a road test.
Check that component 1175 is fitted and attached correctly (the arrow indicating the front of the vehicle).
Check the conformity of the tyres (see MR 411, Mechanical, 35A, Wheels and tyres, Tyres: Identification
and Tyre pressure, Identification).
