– The resistance should be between 43 and 49Ω at 25°C,
– Replace the solenoid valve if the resistance is outside the tolerance values.
Check the continuity, insulation, and the absence of interference resistance of the following connection:
Injection computer, brown 48-track connector B, track J4 Track 1 damper valve solenoid valve
Repair if necessary.
If the fault is still present, contact the Techline.

IMPACT DETECTED SIGNAL
NOTESFault finding procedure application conditions:
Only apply the procedure if the fault is present and if the vehicle does not start.
Special notes:
The fault appears when the injection computer receives a frontal impact signal from the
Airbag computer via the multiplex network.
As soon as the injection computer receives this signal, engine operation is inhibited
and the level 2 warning light is lit.
Use bornier Ele. 1681 for all operations on the injection computer connectors.
If the vehicle has been involved in an accident:
Carry out any necessary repairs:
– clear the fault,
– switch off the ignition and wait 30 seconds,
– wait for the engine immobiliser indicator light to flash,
– switch on the ignition,
If the fault does not reappear, end of fault finding procedure.
If the fault recurs, carry out fault finding on the AIRBAG computer.
If the vehicle has not been involved in an accident, carry out fault finding on the Airbag computer.
AFTER REPAIRDeal with any faults.
Carry out a road test, then check with the diagnostic tool.

NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after the clutch pedal is depressed, or during a road test.
Special notes:
Use bornier Ele. 1681 for all operations on the injection computer connectors.
WARNING
This fault may appear if the wiring harness has been damaged.
Follow the procedure described in the Wiring Check in the Introduction.
This check enables the condition and the conformity of the engine wiring harness to be checked.
Check the conformity and adjustment of the clutch switch (position, connection).
– display status ET405 Clutch pedal switch,
– when the clutch pedal is engaged, status ET405 should be INACTIVE,
– when the clutch pedal is disengaged, status ET405 should be ACTIVE,
If these checks are not OK, replace the clutch switch.
If these checks are correct:
Check the connections of the clutch pedal switch.
Check the injection computer connections.
Repair if necessary.
Check for continuity and the absence of interference resistance on the following connection:
Injection computer black 32-track connector A, track C4 Track 1 Clutch pedal switch
Repair if necessary.
Check for earth on track 2 of the clutch pedal switch.
Repair if necessary.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test, then check with the diagnostic tool.

Check the injection computer connections.
Repair if necessary.
Carry out a fault finding procedure on the multiplex network and ABS.
See 88B Multiplexing and 38C ABS to deal with any faults.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test, then check with the diagnostic tool.

NOTESPriority when dealing with a number of faults:
In the event of more than one fault:
–DF056 Air flow sensor circuit,
–DF057 Water in diesel fuel detector circuit,
–DF067 Damper control circuit,
Check the conformity of the + 12 V after relay supply line,
from track 2 of the UPC PPM1 connector.
(Use the Wiring Diagrams Technical Note for the vehicle).
Check the camshaft sensor connectors,
Check the injection computer connections.
Check that the camshaft sensor is correctly positioned and mounted.
Also check the general condition (damaged housing, heating up, etc.).
Carry out the necessary repairs.
Check the continuity and absence of interference resistance of the following connections:
Injection computer brown 48-track connector B, track D1 Track 2 Camshaft sensor
Injection computer brown 48-track connector B, track A1 Track 1 Camshaft sensor
Repair if necessary.
Check the camshaft sensor resistance between tracks 2 and 3.
If the resistance is not 10250Ω ±500 at 20°C, replace the sensor.
AFTER REPAIRDeal with any faults.
Carry out a road test, then check with the diagnostic tool.

With the ignition on and the camshaft sensor connected:
Use a voltmeter to measure the voltage between tracks 1 and 3 of the camshaft sensor:
The voltage displayed should be equal to the battery voltage 0.08 V)
if the voltage is outside permitted tolerance values, take the measurement again with the camshaft sensor
disconnected.
If the voltage is still outside the permitted tolerance values with the sensor disconnected, check the continuity and
absence of interference resistance on the following connection:
Camshaft sensor, track 3 Track 2, PPM1 UPC black connector
If the voltage displayed is correct with the sensor disconnected, replace the camshaft sensor.
If the fault is still present, check the timing adjustment.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test, then check with the diagnostic tool.
