Fault finding – Conformity check37B
SUB FUNCTION: EMERGENCY BRAKING (CONTINUED 2)
NOTESOnly carry out this conformity check after carrying out a complete check using the
diagnostic tool.
Application conditions: ignition on (forced + after ignition, see Introduction)
Note:
The interpretation of these statuses and parameters is only valid with the
ignition switched on, the statuses and parameters displayed in blue on the
diagnostic tool is information supplied by other computers, which are transmitted via
the multiplex network. If these variables display inconsistent values, check that the
multiplex system test has not shown up any faulty connections. Repair the faulty
multiplex connections before looking for a possible problem with the signals.
Each sub-function in this test is associated with a Fault finding chart.
Special notes:
The diagnostic tool may display the message Computer busy when displaying
statuses and parameters. This message is displayed when the parking brake is
applying or releasing the brake, because the computer gives priority to controlling the
motor before transmitting variables. If this message is displayed, exit the current
screen and then return to it.

1Parking brake
assistPR005:Force setting In rest position:
X = 0 N
When applying the brake
on a level surface:
400 < X < 550 N
When fully applied (lever
fully pulled for 2 seconds)
on a level surface:
1100 < X < 1150 N
Note:
depressing the brake
pedal once when the
parking brake is applied
changes the measured
value of the force (change
in the tension of the brake
cables) and the parking
brake may be over-
applied.
Interpretation of these
parameters is only valid
without any pressure
on the brake pedal.The difference between the
reference and measured values
must not be more than - 50 N or
+100N. If the measured value
does not reach or exceeds the
reference value (mechanical or
electrical fault with the control),
the electronic parking brake
computer will detect a fault
(DF025 Vehicle movement
with maximum application,
DF049 Brake application or
DF050 Mechanical jamming).
If one of these three faults is
displayed by the diagnostic tool,
use the relevant interpretation. PR004:Measured force

+ AFTER IGNITION FEED
NOTESNone
This status means there is a + 12 V computer after ignition.
When the ignition is switched off, the status displays: ABSENT.
When the ignition is switched on, the status displays: PRESENT.
If the status does not operate as specified: disconnect the electronic parking brake computer connector to check
the insulation, continuity and the absence of interference resistance on the following connections:
Automatic parking brake computer connector
track H4
(except Laguna II, Vel Satis and Espace IV) track G4 + 12 V
track H2
(except Laguna II, Vel Satis and Espace IV) track G2 earth
Repair if necessary (see the vehicle wiring diagram).
If the connections are correct, the power is correctly supplied to the electronic parking brake computer, but the
fault is still present, contact the Techline.
AFTER REPAIRRepeat the conformity check from the start.

AUTOMATIC BRAKING CONFIGURATION
NOTESSpecial notes:
To understand the operation of assisted brake application, refer to System operation.
This status indicates the assisted braking configuration status.
This configuration can be checked on two screens.
●Configuration reading screen (repair mode): LC009 Vehicle configuration (NORMAL with braking, COLD
CLIMATE without assisted braking).
●Variables screen (fault finding mode, assisted brake application sub-function).
ET022 Automatic braking configuration.
When the assisted braking is ACTIVE, the status should be WITH.
When the assisted braking is not ACTIVE (for cold countries, for example), the status should be WITHOUT.
If the configuration does not match the customer's request, reconfigure the electronic parking brake computer by
activating configuration CF007 Vehicle configuration (repair mode, see Configuration and programming).
AFTER REPAIRRepeat the conformity check from the start.

NOTESNone
This parameter shows the vehicle's angle on a slope (X-axis).
The value displayed represents degrees (and not percentage grade).
Normally, this parameter should display:
– On level ground: - 2d° <X <+ 2d°
– Possible values, depending on slope: -25d°<X<+25d°
If the values displayed are not correct, contact the Techline.

BRAKING
NOTESSpecial notes:
The commands are found in the tool's fault finding mode, Actuator command button.
Running this command tightens the electronic parking brake cables.
It can therefore be used to test operation of the electronic parking brake motor, either to display a present fault or
to test motor operation in the event of a control lever failure.
Note:
Before running this command, check that the brake cables are correctly fitted and that no one is working
on the vehicle.
Only run this command with the parking brake released.
AFTER REPAIRRepeat the conformity check from the start.
