Fault finding - Introduction
1. SCOPE OF THIS DOCUMENT
This document presents the fault finding procedure applicable to all computers with the following specifications:
2. PREREQUISITES FOR FAULT FINDING
Documentation type:
Fault finding procedures (this document):
–Assisted fault finding (integrated into the diagnostic tool), Dialogys.
Wiring Diagrams:
–Visu-Schéma (CD-ROM)
Type of diagnostic tools:
–CLIP
Special tooling required:
3. REMINDERS
Procedure
To perform fault finding on the vehicle's computers, switch on the ignition in fault finding mode.
Proceed as follows:
–vehicle's card in reader;
–press and hold the Start button (longer than 5 seconds) with start-up conditions not fulfilled,
–connect the diagnostic tool and perform the required operations.
To cut off the + after ignition feed, proceed as follows:
–disconnect the diagnostic tool,
–press the Start button twice briefly (less than 3 seconds),
–ensure that the + after ignition feed has been cut off by checking that the computer indicator lights on the
instrument panel have gone out. Vehicle(s): SCENIC II ph2

ET018
BRAKE PEDAL
Note:
Status ET018 "Gear engaged" is applicable to the following sub-functions:
–"Driver parameters".
STATUS
DEFINITIONDEPRESSED: shows that the brake pedal is depressed.
RELEASED: shows that the brake pedal is released.
STATUS1: shows that the brake switch signal is invalid.
NOTESSpecial notes:
Apply the conformity check to see if the statuses are consistent with the operating
programs of the system.
Conformity check with engine stopped, ignition on or engine running.
"DEPRESSED"
(Brake pedal
depressed)
When the driver depresses the brake pedal status ET018 Brake pedal becomes
DEPRESSED.
If the driver depresses the brake pedal hard and status ET018 Brake pedal remains
RELEASED with the lights operating:
Check the insulation, continuity and the absence of interference resistance on the
following connection:
–Connection code 5A
between the brake light switch connector, component code 160 and the transmission
computer, component code 119.
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.
–Remove the brake light switch and carry out the following checks:
Continuity between
connectionsInsulation between
connections
Brake pedal depressed65A and SP17 5A and BPT
Brake pedal released5A and BPT 65A and SP17
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

"STATUS 1"
If the checks are not in order, replace the brake light switch.
If the driver depresses the brake pedal and status ET018 Brake pedal is DEPRESSED
but the brake lights do not operate:
–Check the condition and fitting of the brake light switch, the brake light fuse and the
brake light bulbs.
–Check for + after ignition feed on connections SP17 and BPT on the brake light
switch.
When the driver releases the brake pedal status ET018 Brake pedal becomes
RELEASED.
If this does not happen, check that the brake light switch is in good condition and
operating correctly by carrying out the checks associated with status DEPRESSED.
Check the status and operation of the brake light switch by performing the checks
associated with the "DEPRESSED" status.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
