CRUISE CONTROL/SPEED LIMITER
STATUS DEFINITION
NOT DETECTED: This status indicates that the cruise control or speed limiter function
is not present on the vehicle.
INACTIVE: This status indicates that the cruise control/speed limiter main On/Off
switch is in the rest (or neutral) position.
SPEED LIMITER: This status indicates that the driver has used the main switch to
select the speed limiter.
CRUISE CONTROL: This status indicates that the driver has used the main switch to
select the cruise control.
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
NOT
DETECTED
If the vehicle does not have cruise control or speed limiter function buttons, status ET042
is permanently NOT DETECTED. This confirms that the cruise control/speed limiter
function is not present on the vehicle.
If the vehicle is fitted with cruise control or speed limiter function buttons, the main switch
is in the rest (or neutral) position and the injection computer has just been programmed
or reprogrammed, then status ET042 is NOT DETECTED.
To activate the cruise control or speed limiter function, press the main switch in the cruise
control position and then in the speed limiter position.
Return to rest position
The tool displays status ET042 INACTIVE.
If not, several steps must be checked:
1 Return to the multiplex network test page on the Clip application. Repeat the multiplex
network test. Re-establish dialogue with the injection computer. Check status ET042.
If ET042 is INACTIVE, the injection computer has detected the various positions of the
main switch. The cruise control/speed limiter is activated.
2 If ET042 is NOT DETECTED, check that the owner of the vehicle has not, sometime
in the past, asked for the cruise control/speed limiter function to be deactivated.
Contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

PR037
REFRIGERANT PRESSURE
NOTESThere must be no present or stored faults.
Perform this fault finding procedure after an inconsistency is displayed in the
Parameters menu or after a customer complaint (no air conditioning, etc.).
Step 1
– Start the engine, switch on the air conditioning and increase the engine speed to 1,500 rpm:
– Display PR037 Refrigerant pressure in the Cold loop function on the diagnostic tool:
If the pressure is greater than ~27bar, go to step 2.
If the pressure does not rise, or remains below normal:
– Ensure that the air conditioning compressor and the relay are operating correctly.
– Check the conformity of the refrigerant pressure sensor by comparing* the value displayed by the tool (PR192)
with the reading given by the charging station high pressure gauge.
If the pressure difference = ±1.5bar, (or 1500 mbar):
Check the continuity and the absence of interference resistance on the connections between:
Injection computer, grey 24-track connector C,
track C3Track A of the refrigerant pressure sensor
Injection computer, brown 48-track connector
B, track F1Track C of the refrigerant pressure sensor
Injection computer, brown 48-track connector
B, track F3Track B of the refrigerant pressure sensor
If these connections are not faulty, replace the refrigerant pressure sensor.
If there is no difference, the refrigerant pressure sensor is correct: go to step 2.
Step 2
– Perform fault finding on the air conditioning.
*Note:
The diagnostic tool displays the absolute pressure, the charging station high pressure gauge displays the relative
pressure.
The normal difference between the two is equal to atmospheric pressure, i.e. ~1,000mbar.
AFTER REPAIRRepeat the conformity check from the start.
