NOTESNone.
Try the diagnostic tool on another vehicle.
Check:
– the connection between the diagnostic tool and the diagnostic sensor (wiring in good condition),
– the connection between the diagnostic sensor and the diagnostic socket (lead in good condition),
– the engine and passenger compartment fuses.
Check for + 12 V battery on track 16, and + 12 V after ignition feed on track 1 and an earth on track 5 and on
track 4 of the diagnostic socket.
Repair if necessary.
Disconnect the automatic or electronic parking brake computer connector to check the insulation, continuity
and 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
track A4 track 7 of the diagnostic socket (K line)
Repair if necessary (see the vehicle wiring diagram).
AFTER REPAIRCarry out a check using the diagnostic tool.
Deal with any other faults.

Carry out a multiplex network test (see 88B, Multiplexing) and check for any potential incorrect multiplex line
signals from the injection computer (see 13B, Diesel injection or 17B, Petrol injection), the automatic gearbox
computer (see 23A, Automatic gearbox) the UCH computer (see 87B, Passenger compartment connection
unit) and the Protection and Switching Unit computer (see 87G, Engine compartment connection unit).
Test the braking system:
Look for any areas where the brake pads may be sticking (due to ice, salt, etc.).
Check that the brake piston is operating correctly.
Repair if necessary.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a check using the diagnostic tool.
Deal with any other faults.

ALP4 Assisted braking fault (when the engine is stopped)
NOTESOnly consult this customer complaint after a full check using the diagnostic tool
(no present or stored faults).
(see the wiring diagrams technical note for the vehicle concerned).
Check for any potential faults in the ABS computer (see 38C, Anti-lock braking system), the UCH computer
(see 87B, Passenger compartment connection unit) and the injection computer (see 13B, Diesel injection or
17B, Petrol injection) to ensure that they have actually received a request to stop the engine.
Test the application of the electronic parking brake with the engine switched off.
Incorrect signal faults on the multiplex line.
Run a multiplex network test (see88B, Multiplex).
When the engine stalls, the automatic brake application function is not active.
Check the + 12 V supply, the insulation, continuity and the absence of interference resistance on the
following connection:
– connection code BP2
Between the electronic parking brake computer, component code 1217 and the battery, component code 107.
If the continuity is correct, test the charging circuit (see Technical Note 6014A, Checking the charging circuit).
Repair if necessary.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a check using the diagnostic tool.
Deal with any other faults.

(no present or stored faults).
Check that the engine has not stalled whilst driving.
Check that the electronic parking brake is actually released.
Check that the injection control system is not in defect mode (engine Limp Home).
Run a multiplex network test (see88B, Multiplex).
Check for any potential faults in the injection computer (see 13B, Diesel injection or 17B, Petrol injection).
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a check using the diagnostic tool.
