BRAKE PEDAL POSITION
NOTESThe accessories relay must operate.
During pedal travel, it is possible to obtain an undetermined or inconsistent status for
status ET047 if the brake pedal is left in an "indeterminate zone", with the brake pedal
switch in between the released position and the depressed position (see System
operation).
This treatment applies only in cases in which the status is inconsistent or
undetermined, with full load on the accelerator or completely released from the brake
pedal.
Special note:
Switch on forced after ignition.
Use Wiring Diagrams Technical Note for MEGANE II or SCENIC II.
ET047 Inconsistency with the pedal depressed.
Check the condition and connection of the brake pedal switch connector.
If the connector is faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector; otherwise, replace the wiring.
Remove the brake pedal switch and check the insulation between connections BPT and 5A of component 160
(switch piston free).
Only replace the brake pedal switch if it is not correct.
Check the condition and connection of the UCH connector PE2.
If the connector is faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector; otherwise, replace the wiring.
With the UCH and brake pedal switch disconnected:
Check the insulation from + 12 V of the following connection:
●Connection code 5A, between components 645 and 160.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
The line is shared with the injection computer and the automatic transmission computer (if the vehicle is fitted with
an automatic transmission). In the event of faulty insulation, use a wiring diagram to check the connections
between the brake pedal switch connector and these computers.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other faults.
