STOREDWHEEL SPEED CONSISTENCY
DEF: inconsistency
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
