ET673JAMMED ACCELERATOR PEDAL–YES
–NO
STATUS
DEFINITIONYES: This status indicates that the accelerator pedal is detected to be jammed.
NO: This status indicates that the accelerator pedal is not detected to be jammed.
NOTESSpecial notes:
Apply this procedure only if the status is YES.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III
or MODUS.
Conformity check: Engine stopped and ignition on, or engine running, and engine coolant
temperature > 80˚C
YES
OR
NOThis status varies when the ignition is on or the engine is running depending on the
status of the accelerator pedal.
Check the condition of the connectors of the brake switch (component code 160), of the accelerator potentiometer
(component code 921), and of the engine management computer (component code 120).
If the connector or connectors are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.

Measure the resistance of pedal potentiometer gang 1 between connections 3LR and 3LT.
If the resistance is not between:
0.8 kΩ < X < 2.6 kΩ, replace the pedal potentiometer.
Measure the resistance of the pedal potentiometer gang 2 between connections 3LU and 3LV.
If the resistance is not between:
0.8 kΩ < X < 4.9 kΩ, replace the pedal potentiometer.
Check the brake switch (see interpretation of faults, DF228 Brake signal or DF623 Closing brake signal).
Use the universal bornier to check the insulation and continuity of the following connections:
●3LT between the components 120 and 921,
●3LR between the components 120 and 921,
●3LS between the components 120 and 921,
●3LU between the components 120 and 921,
●3LV between components 120 and 921,
●3LW between the components 120 and 921,
●5A between components 120 and 160.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Carry out a multiplex network test.
Carry out complete fault finding on the UCH (see 87B, Passenger Compartment Connection Unit).
Clear RZ001 Fault memory.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

ET674REFRIGERANT PRESSURE–Too low
–Correct
–Unavailable
STATUS
DEFINITIONTOO LOW: this status indicates that the refrigerant pressure is too low.
CORRECT: this status indicates that the refrigerant pressure is correct.
UNAVAILABLE: this status indicates that the refrigerant pressure is unavailable.
NOTESDeal with DF232 Refrigerant pressure sensor circuit first.
There must be no present or stored faults.
Conformity check: Engine stopped and ignition on, or engine running, and engine coolant
temperature > 80˚C
TOO LOW
or
CORRECT
or
"UNAVAILABLE"The purpose of this status is to check that the circuit is correctly charged with gas.
It becomes active when the air conditioning is detected as being connected and there
are no faults present.
The result of this status is:
–Too low: Pressure below 2 bar.
–Correct: Pressure above 2 bar.
–Unavailable: Cannot perform test.

Sensor electrical conformity
INACTIVEStatus ET703 becomes INACTIVE when none of the cruise control / speed limiter
buttons is pressed. These buttons are located on the steering wheel.
To carry out the checks and measurements in complete safety, observe the driver's
frontal airbag removal recommendations (see MR 392 (Clio III), MR 385 (Modus),
MR 411 (New Twingo), or MR 442 (E33), Mechanical, 88C, Airbag and
pretensioners, Driver's frontal airbag: Removal - Refitting).
If status ET703 does not display INACTIVE,
–check the condition of the cruise control/speed limiter +/- button and the condition
of its connector.
–check the condition of the cruise control/speed limiter "R/0" button and the
condition of its connector,
If the connector(s) is 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.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
