Bargraphs 2, 3, 4 or 5 right or left hand side flashing
Solenoid valve circuit

Even if present at time of testing, these faults will always be declared by a
flashing bargraph.
To confirm their presence and therefore the need to apply the fault finding
described below start command G20*. The fault is present if the bargraph
appears illuminated at the end of the command.
If bargraph 11 left hand side is also illuminated, deal with bargraph 11 left hand
side as a priority.
NOTES
Fiche n° 532 - 3 - 4 - 5
Check the ABS earths (tightening of the two screws above the hydraulic assembly).
Check the condition and position of the 60A ABS fuse in the engine connection unit (white mounting).
Check the connection and condition of the connections on the 31 track connector of the computer.
Erase the computer memory, exit the fault finding mode(G13*) switch off the ignition.
Switch on the ignition and carry out a new test with the XR25 kit, using command G20*.
If the fault "solenoid valve circuit"reappears, replace the ABS computer.

If all the checks are correct, reconnect the computer then erase its memory with command G0**.
Leave fault finding mode(G13*) and carry out a road test. Replace the computer if the fault reappears.
Carry out operations necessary for obtaining correct voltage between tracks 19 and 17/18 of the 31-track
ABS computer connector (9.4 volts < correct voltage < 17.4 volts) :
- Check tightness and condition of battery terminals.
- Check the 60A fuse in the engine connection unit (white base).
- Ensure continuity between the 60A fuse and tracks 17 and 18 of the computer connector.
- Check the ABS earths (tightening of the two earth bolts above the hydraulic assembly).
- Check/ ensure continuity between the ABS earth and track 19 of the computer connector.
None.

Only consult this section after a complete check with the XR25 kit.NOTES
yes
Look for a short circuit to earth of the
connection between track 10 of the R36
connector and the ABS warning light (track
3 of the black instrument panel connector).Look for a fault in the shunt or a short
circuit to earth of the connection between
track 21 of the computer connector and R36
on track 10.
no
Disconnect the computer and check the
shunt positioning in the 31 track connector
(between track 19 and track 21).
Ensure on the computer side that a shunt
opening pin is present between tracks 19
and 21 of the computer connector.
Reconnect the computer.
Check that there is continuity between
track 10 of the R36 connector on the engine
compartment side, and earth.
Is continuity ensured ?

TEMPORARY ILLUMINATION OF ABS WARNING LIGHT WHEN DRIVINGFault chart 3
Check the voltage of the computer power supply : 9.5 volts < correct voltage < 17.5 volts.
If necessary, carry out the following operations :
- Check the battery charge (check the charging circuit if necessary).
- Check the tightness and condition of the battery terminals.
- Check the ABS earths (tightness of two earth bolts above the ABS assembly).
Disconnect the computer and check the condition and the positioning of the shunt in the 31 track
connector (between track 19 and track 21).
Check on the computer side, the condition of the shunt opening pin.

DESCRIPTION OF BARGRAPHS
Illuminates when dialogue is established with the product computer, if it remains extinguished :
- the code does not exist,
- there is a line , computer or tool fault.
REPRESENTATION OF FAULTS (always on coloured background)
Illuminated, indicates a fault on the part tested, the associated text defines the fault.
Extinguished, indicates non-detection of fault on the product tested.
REPRESENTATION OF STATUS (always on white background)
Engine stopped, ignition on, no operator action
Status Bargraphs on the fiche are shown as they should appear, engine stopped, ignition on, without

18 track decoder unit connector and track ** of the injection computer .
Repair the wiring if necessary.
Set the XR25 to pulse sensor mode (button "G", input on terminal "Vin").
Ignition on, check for pulses on track A6 of the decoder unit connector (test with decoder unit and
solenoid valve coded electronic unit connectors connected).
Are there any pulses ?
Replace the injection computer.YES
