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).

CC.1: short-circuit to +12 volts
NOTESSpecial notes:
This fault indicates that the wheel speeds are inconsistent with each other.
The computer does not know how to determine which one is faulty.
Priorities when dealing with a number of faults:
Deal first with faults DF090 Front right-hand wheel target, DF091 Front left-hand
wheel target, DF092 Rear right-hand wheel target and DF093 Rear left-hand wheel
target even if they are stored.
Use the Wiring Diagram Technical Note for New Twingo.

NOTESConditions for applying the fault finding procedure to
stored faults:
The fault is declared present after a road test.
Check the quality of the mounting of the wheel speed sensors (correct clipping without excessive play).
Check the conformity of the targets (condition, number of teeth = 48) using the specific command SC001 Check
target teeth for each wheel.
Are the numbers of teeth correct?
YESVisually inspect the condition of the axles (impacts, deformations, etc.) and check that
the tyre mountings conform and are in good condition (see MR 411, Mechanical, 35A,
Wheels and tyres, Identification).
Ensure that the braking system is in good condition (condition of the linings, tightness,
grip, bleeding, bearing play, lubricant on the targets, etc.).
NOApply the target fault procedure for the wheel(s) concerned:
–DF090 Front right-hand wheel target
–DF091 Front left-hand wheel target
–DF092 Rear right-hand wheel target
–DF093 Rear left-hand wheel target
