STATUSES
CLEARING
Control
*csv: ET017: Brake pedal.
This status gives the position (depressed or released) of the brake pedal
ET023: ESP On/Off button
This status is used to check the ESP On/Off button operation. This status (pressed or released) is
checked by keeping the button pressed.
ET030: Automatic brake light illumination.
This status indicates whether automatic brake lighting is authorised or inhibited during CSV
(understeer control)*. The parameters of this status can be modified using commands VP021 and
VP022 according to the legislation in force in the country concerned.
RZ001: Fault memory.
This command is used for clearing the computer's stored faults.
RZ003: ESP sensor programming (Vdiag 09, 0A, 0B, 12 and 11).
This command resets the ESP sensor programming. Run this command every time work on the
electric power steering required programming of the steering wheel angle or after any operation on
the axle assemblies. Use this command when the combined sensor has been removed or replaced.
AC003:
AC004:
AC005:
AC006:Front left-hand wheel solenoid valves.
Front right-hand wheel solenoid valves.
Rear left-hand wheel solenoid valves.
Rear right-hand wheel solenoid valves.
These commands permit a check on the hydraulics of each wheel.
Raise the vehicle in order to be able to rotate the wheels, and check that they rotate freely.
Keep the brake pedal depressed to prevent the wheel being tested from being turned by hand
(do not brake so firmly that full braking power is reached).
Select and confirm the command for the wheel concerned (e.g. Front left-hand wheel solenoid valve,
etc.)
Turn the wheel concerned by hand; you should see it go through 5 locking/unlocking cycles.
AC013:Test wheel speed sensor feed (Vdiag 0A, 0B, 12 and 11).
This command is used to check that voltage pulses of approximately 12 V are detected by a
multimeter at the sensor connector terminals on the computer side. You must use command AC013
once only.
AC016:Pump motor test.
This command is used to test the pump motor control circuit. Select command AC016 Pump Motor
Test. The motor must run for 5 seconds.
AC187:Brake light on relay.
This command is for testing brake light activation by the ESP when controlling understeer during sharp
deceleration.

COMMAND (continued)
SPECIAL COMMANDSAC195:Vehicle speed signal.
This command sends a speed other than 0 mph on the computer's vehicle speed wire output
(Track 33) to users of that signal (xenon bulbs, radio, sunroof).
Note:
This command has no visible effect on the dashboard speedometer needle.
Xenon bulbs: Switch on the dipped headlights and run command AC195. You should see a slight
change in the height of the headlight beam (depending on vehicle speed, the height of the beam is
adjusted to improve visibility).
–Radio: switch on the radio and check that the speed-dependent volume control function is active.
Run command AC195. During the command, you should notice the volume of the sound increase
and then decrease.
–Sunroof: this command has no visible effect on the sunroof. This command changes the activation
threshold of the anti-pinch system (the pressure exerted by the sunroof varies with vehicle speed
due to aerodynamic factors).
AC196:Request to switch on hazard warning lights.
This command sends the UCH a request to switch on the hazard warning lights to test their operation
during emergency braking (depending on UCH configuration).
SC001: Check target teeth.
This command tests the condition of the teeth on each wheel. Select command SC001 Test target
teeth. The test result should show 48 teeth.
SC006: Bleed the hydraulic unit and brake circuits.
Use this command if abnormally long brake pedal travel is noted during a road test with ABS control
(the system must have been bled beforehand by the usual procedure).
Select the SC006 "Bleed hydraulic unit and brake circuit" command and follow the instructions
given by the diagnostic tool.

the pedal position.
STATUS Released Brake pedal depressed.
If the brake lights are working:
–Check the continuity of the connection between track 1 of the brake light switch connector and track 30 of the
computer connector.
If the brake lights are not working:
–Check the brake light lighting relay,
–Check the condition and fitting of the brake light switch and brake lights fuse.
–Remove the brake light switch and check that it is operating correctly:
Continuity between tracks Insulation between tracks
Switch pressed
(Brake pedal released)3 and 4 1 and 2
Switch released
(Brake pedal depressed)1 and 2 3 and 4
–Replace the switch if necessary.
–Check for + after ignition feed on tracks 2 and 4 on the brake light switch connector.
If the brake lights still fail, check/ensure the continuity between track 1 of the switch connector and track 4 of the
relay mounting.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.

ALP 3 Pull
NOTESOnly consult this customer complaint after a complete check with the diagnostic tool.
Disconnect one wheel speed sensor. Start the
engine and check that only the ABS fault warning
light comes on. Do not drive the vehicle if the brake
fault warning light is also lit, as the brake limiter
function is no longer guaranteed to operate
correctly. Carry out a road test with the ABS
deactivated.
Is the fault still present under these conditions?
no
Raise the vehicle so that you can rotate the wheels
and check:
–Possible inversion when connecting the speed
sensors.
–Possible inversion of pipes on the hydraulic unit.
To carry out these two tests, refer to and follow the
procedures given in ALP 2.
Check the condition of the ABS targets and that they
conform to specifications.
Also check the sensor/target air gap over one
revolution of each front and rear wheel.
If the fault is still present, contact the Techline.
yesIf the brake pedal travel is relatively long,
bleed the brake circuit.
If the travel is normal, check the tyre
pressures, the front axle, or for any leaks
in the circuit.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.

light comes on. Do not drive the vehicle if the brake
fault warning light is also lit, as the brake limiter
function is no longer guaranteed to operate
correctly. Carry out a road test with the ABS

Is the fault still present under these conditions?
no
Normal behaviour linked to the system operation
during the regulation phase, mainly on surfaces with
uneven grip or which are poorly laid.
yesRoad handling fault not connected with
the ABS.
Check the condition of the brake linings
and that they are to specification and
check the tyre pressures, the front axle,
etc.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.

ALP 5Unexpected ABS operation at low speed and with slight
pedal pressure
NOTESOnly consult this customer complaint after a complete check with the diagnostic tool.
Important: ABS regulation may be unresponsive when the vehicle is driven on surfaces
such as icy roads, cobbled streets, etc.
It is possible to feel brake pedal vibrations which are associated with the reaction of the system in particular
circumstances, such as:
–crossing rumble strips,
–tight cornering with lifting of the inside rear wheel.
These vibrations may be linked to simple brake limiter activation, when the pressure on the rear axle is limited.
If the fault is different, check the speed sensor connectors (micro-breaks) as well as the air gaps.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.
