LOCKING OF ONE OR MORE WHEELSFault chart 4
REMINDER:Wheel locking on a vehicle equipped with ABS, or tyre squeal, considered by the customer
as locking, can be linked to a normal reaction of the system and should not be systematically
considered as a fault :
- locking is allowed below 3.75 mph ( 6 km/h) (the system will not provide regulation).
- Braking with ABS regulation under very bad road conditions (high degree of tyre squeal).
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Only consult this section after a complete check with the XR25 kit.NOTES
On the other hand, if there really is wheel locking on one or more wheels, lift the vehicle so the wheels can
be turned, and check :
- a possible incorrect connection in the speed sensor connection.
• Use operations #01, #02, #03 and #04 while turning the appropriate wheel and ensure the consis-
tency of the results obtained .
• If the value measured is zero, turn the other wheels to confirm a bad electrical connection of the sen-
sors and repair the wiring.
- A possible incorrect connection of the hydraulic assembly pipes.
• Use operations G03*, G04*, G05* and G06* while applying the brake and check for the ten cycles of
unlocking/locking on the wheel concerned (consult section "Aid").
• If the ten cycles do not occur on the wheel tested, (wheel remains locked), see if they occur on ano-
ther wheel (if a bad connection is confirmed: repair).
• If the ten cycles do not occur on a wheel and the pipes are correctly connected, replace the hydraulic
assembly.
• Check the condition of the ABS targets and that they conform.
• Also check the sensor/target air gap by rotating each of the wheels :
Front 0.13 mm < air gap over one rotation < 1.96 mm.
Rear 0.03 mm < air gap over one rotation < 2.4 mm (check only possible on vehicles with four-bar
rear axles).
If the fault persists after these checks, replace the hydraulic assembly.

UNEXPECTED ABS OPERATION WHEN USING SPECIAL
EQUIPMENT (MOBILE PHONE,CB...)Fault chart 9
Check that equipment causing the problem during use is approved.
Check that this equipment has been correctly installed without modification to the original wiring, in
particular, that of the ABS (connections to earth and + after ignition/ before ignition of the ABS are not
permitted).

Check that lines K and L are not being disrupted by another computer.NOTES
Fiche n° 56
Check the condition of +before ignition feed fuse.
Change the fuse if necessary.
Ensure that the XR25 kit is not the cause of the fault by trying to communicate with another computer on
the vehicle (air conditioning computer, injection computer...).
Check that the ISO interface is in position S8, that the most recent version of the XR25 cassette and the
correct access code are being used(D 56).
Check battery voltage (U > 10.5 volts). Recharge the battery if necessary.
Check that the 18 track decoder unit connector is properly connected.
Check that the decoder unit is properly fed :
-earth on track A8 of the decoder unit connector.
-+ before ignition feed on tracks A9 and A1 of the decoder unit connector.
Ensure that the diagnostic socket is correctly fed.
Check and ensure the continuity and insulation of the wiring of tracks A3 and A4 of the decoder unit
connector.
If there is still no dialogue between the XR25 kit and the decoder unit, change the decoder unit.
