Check that the wheel speed sensor mounting 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.
For versions equipped with disc brakes:
Check the sensor/target air gap through one wheel revolution (0.1 < rear wheel air gap < 0.9 mm).
If the air gap is incorrect:
–Replace the instrumented bearing/wheel sensor mounting assembly (see MR 411, Mechanical, 33A, Rear axle
components, Rear hub carrier bearing: Removal - Refitting).
If the air gap is correct.
–Swap both rear wheel brake discs as well as the brake pads.
–Clear the computer fault memory.
–Carry out a road test followed by another check with the diagnostic tool.
–If the fault initially declared as DF092 has become DF093 Rear left-hand wheel target, replace
the instrumented bearing/wheel sensor mounting assembly (see MR 411 Mechanical, 33A, Rear axle
components, Rear hub carrier bearing: Removal - Refitting).
–If the fault remains on the same side, replace component 150 (see MR 411, Mechanical, 38C, Anti-lock
braking system, Wheel speed sensor, Removal - Refitting).
For versions equipped with drum brakes:
–Swap both rear wheel brake drums.
–Clear the computer fault memory.
–Carry out a road test followed by another check with the diagnostic tool.
–If the fault initially declared as DF092 has become DF093 Rear left-hand wheel target, replace the target
(see MR 411, Mechanical, 33A, Rear axle components, Rear brake drums, Removal - Refitting).

NOTESPriorities when dealing with a number of faults:
Deal with fault DF007 Left rear 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.

NOCheck that the "Automatic brake light" function is activated using status
ET030 Automatic brake light.
If the status ET030 "Automatic brake lights" is "PROHIBITED":
inhibit or authorise the automatic brake lights (depending on the country's legislation)
using command VP021 Automatic brake light inhibition or VP022 Automatic brake
light authorisation.
Check the condition and position of fuse F5 (15 A) in the passenger compartment
fuse box (see 81C, Fuse box).
Connector of components 1281, 1094 and intermediate union R107 disconnected,
Check the continuity of connection 4GJ between component 1281 and intermediate
union R107.
Check the continuity of connection 4GJ between intermediate union R107
and component 1094.
If the connections are faulty (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
With the connector of components 1281 and 1016 disconnected, check the continuity
and insulation of connection AP10 between components 1016 and 1281.

NOTESConditions for applying the fault finding procedure to stored faults:
Clear the stored fault, carry out a road test at a speed of > 36 mph (60 km/h) and test
the brakes using ABS.
Use the interpretation of the fault if it recurs.
Special notes:
The fault is detected if the computer does not detect a brake lights switch status change
for 4 acceleration/braking cycles and/or the contact is closed for over 6 minutes with
the vehicle speed above 24 mph (40 km/h).
Using the diagnostic tool, check on the status screen that ET017 Brake pedal recognises the correct pressed
and released positions of the brake pedal.
If the correct pedal position is not displayed, use the interpretation of ET017 Brake pedal.
