NOTESSpecial notes:
This fault appears when the computer control section has
overheated.
– A road test may be necessary.
Priority when dealing with a number of faults:
Deal with the statuses CO, CC.0, and CC.1 first if they are
present or stored.
After any operation on the damper valve, run SC036
Reinitialise programming (see Interpretation of
commands).
Check the condition of the damper valve connector (see Wiring Diagram Technical Note, Mégane II ph2,
Scénic II ph2, component code 1461).
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Mégane II ph2, Scénic II ph2, component code 120).
If the connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check that the valve is not mechanically jammed:
With the engine stopped, disconnect the air inlet hose from the damper valve.
Check that the valve is in the open position.
Start, then switch off the engine.
Check that the valve closes when the engine is switched off and then opens again when the engine has stopped.
If this does not happen, replace the damper valve.
Check that the valve is clean and that there is no component preventing it from closing (particularly for 2.DEF).
Clean if necessary.
Check the continuity of the following connections:
– Connection code 3VM between components 1461 and 120.
– Connection code 3VN between components 1461 and 120.
Check the insulation against + 5 V and + 12 V (computer feed) of the following connections:
– Connection code 3VM between components 1461 and 120.
– Connection code 3VN between components 1461 and 120.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
If the fault is still present, contact the Techline.

procedure
Check the connections of the brake pedal switch, the ABS computer, the electronic stability program
computer and the engine management computer.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring:
Precautions for repair), repair the wiring, otherwise replace it.
Check for + 12 V after ignition feed on the connections of the brake pedal switch connector and the
condition of the fuse.
– Connection code AP10 of component 160.
– Connection code SP13 of component 160.
Disconnect the ABS - ESP and check the continuity and insulation against + 12 V and against earth
of the following connection:
– Connection code 65A between components 160 and 1094.
Check that the brake pedal switch is working correctly:
in rest position: infinite resistance continuity between the following connections:
– Connection code 65A of component 160.
– Connection code AP10 of component 160.
depressed: continuity between the following connections:
– Connection code 65A of component 160.
– Connection code AP10 of component 160.
Replace the switch if necessary.
If the fault is still present, carry out fault finding on the anti-lock braking system - electronic stability
program; if no irregularity is detected, then carry out fault finding on the multiplex network.
