NOTESSpecial notes:
Although it is stored in the computer, this fault does not cause the warning lights to
come on or generate a fault message, because the ABS/ESP system is not faulty. The
ABS/ESP system is not faulty, but has received unusable signals from the automatic
transmission. Run fault finding on the automatic transmission with the diagnostic tool.
Note:
The automatic transmission does not always store these transient faults as quickly as
the ABS/ESP.
If there is no stored fault in the automatic transmission computer memory, start the
engine, and if no present fault is displayed, contact the Techline. Once the fault in the
automatic transmission has been repaired, clear the ABS/ESP computer fault memory.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after starting the engine.
Using the diagnostic tool, check in the parameter screen that the PR063 Vehicle parameters truly correspond with
the vehicle undergoing fault finding.
Is PR063 Vehicle Parameters correct?
YES
Carry out a multiplex network test and check the automatic transmission system using
the diagnostic tool.
If the fault is still present, contact the Techline.
Use command VP004 Vehicle parameters to define the appropriate parameters for the
vehicle type.
Clear the computer fault memory.
Exit fault finding mode, switch off the ignition and carry out a new test with the diagnostic
tool.
If the fault is still present, contact the Techline.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.

SIGNAL
NOTESSpecial notes:
Although the fault is stored in the computer, it is not caused by ABS/ESP components,
but it indicates that the ESP is deactivated due to an electric power steering frame
transmission fault. Run fault finding on the electric power steering.
Note:
The electric power steering does not always store these transient faults as quickly as
the ABS/ESP system.
If there is no stored fault in the electric power steering computer memory, start the
engine; if no present fault is displayed, contact the Techline. Once the fault in the
electric power steering system has been repaired, clear the ABS/ESP computer fault
memory.
Priorities when dealing with a number of faults:
Deal with faults DF152 and DF153 first, whether they are present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present when the engine is started up.
Check the condition and correct locking of the blue PEH connector on the UPC (Vdiag 44) or the grey CT1
connector on the UPC (Vdiag 48).
Carry out a multiplex network test and check the electric power steering system using the diagnostic tool. If the
fault is still present, contact the Techline.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.

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.

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.
