NOTESPriorities when dealing with a number of faults:
Deal with fault DF007 Rear left-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 (in excess of 12 mph (20 km/h)
for 2 minutes).
Check the condition of the axle assemblies (impacts, damage, etc.) and the conformity and good condition of the
tyres.
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.
If there is a lot of grease on the target, contact the Techline.
Check that the wheel speed sensor mounting is in good condition.
Check the conformity of the target (condition, number of teeth = 48) using the special command SC001 Check
target teeth.
If there is non-conformity, replace the target.
Check the connection and condition (possible damage to the wiring) of the connector of component 1094.
Check the connection and condition (possible damage to the wiring) of the connector of component 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 for a voltage of approximately 12 V between the two connections of the connector of component 151 near
component 1094.
If a 12 V feed is not present, contact the Techline.
If all the checks are in order, swap the 2 rear wheel brake drums. Clear the computer fault memory.
Switch off the ignition. Switch the ignition back on and carry out a road test.
If the fault initially declared as DF232 "rear left-hand wheel speed" has become present DF231 "rear right-
hand wheel speed", replace the complete drum. (see MR411 Mechanical systems, 33A Rear axle
components).
If the fault remains on the same side, replace the speed sensor (see MR411 Mechanical systems, 38C Wheel
speed sensor, Removal - Refitting).
Important, do not forget to refit the drums to the correct wheels.
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.
