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.

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.
