2.DEFNOTESConditions for applying the fault finding procedure to
stored faults:
The fault is declared present after a road test.
Check the connection and condition (possible wiring damage) of the connectors of components 1094 and 151.
If the connector is faulty (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions
for repair), repair the connector, otherwise replace the wiring.
Check the insulation and continuity of connections 4G and 4H between components 151 and 1094.
Also check the insulation between these 2 connections.
If the connection or connections are faulty (see Technical Note 6015A, Repairing electrical wiring, Wiring:
Precautions for repair), repair the wiring, otherwise replace it.
Inspect the condition of the target (metallic contamination etc.).
Clean the target with 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).

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 151 (see MR 411, Mechanical, 38C, Anti-lock
braking system, Rear 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 DF007 has become DF027 Rear right-hand wheel speed sensor circuit, 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 DF026 Front right-hand 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, 35A, Wheels and tyres, Tyres, Identification
and Tyre pressure, Identification).
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.

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.
