STOREDWATER IN DIESEL FUEL DETECTOR CIRCUIT
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after the engine is started or following a road test.
A) Make sure the water in diesel fuel detection sensor is properly connected.
– If not, clear the fault,
– carry out a road test (speed > 12 mph (20 km/h) at an engine speed of> 1200 rpm) for more than 30 seconds.
– If the fault does not recur, end the fault finding procedure.
– If the fault does recur, go to step B.
B) If the sensor is properly connected:
– drain the diesel filter unit (seeMR 364, 13A, Fuel supply),
– clear the fault,
– carry out a road test (speed > 12 mph (20 km/h) at an engine speed of> 1200 rpm) for more than 30 seconds.
If the fault does not recur, end the fault finding procedure.
C) If the fault recurs:
–Check the continuity and the absence of unwanted resistance on the connection between:
Injection computer, grey 32-track connector C, track A2 Track 3 of the water detection sensor
–Check the power supply to the water detection sensor:
UPC PPM1 black connector track 2 Track 1 the water detection sensor
Earth Track 2 water detection sensor
– Carry out the necessary repairs.
If none of these checks reveal any faults:
– Replace the water detection sensor (see MR 364, 13A, Fuel supply).
– Clear the fault.
– Carry out a road test (speed > 12 mph (20 km/h) and engine speed > 1200 rpm) for more than 30 seconds,
to confirm the repair.
Note:
if the level of water in the fuel filter unit is lower than the sensor electrodes, certain driving conditions (on a bend,
leaning) may causethe injection warning light to light up erratically.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by a check with the diagnostic tool.

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.

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.
