STOREDWATER IN DIESEL FUEL DETECTOR CIRCUIT
NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the engine is started or following a road test.
Check the conformity of the fuel used by applying test 10 Diesel fuel conformity check.
Check the sealing of the tank and low pressure circuit by applying test 2 Low pressure circuit check.
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) and engine speed > 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 C.
B) If the water detection sensor is absent:
–Insulate the electrical connector not connected to the vehicle (risk of dampness, oxidation, and erratic
appearance of faults).
Check that the configuration reading LC065 Water detected in the diesel is NONE.
If LC065 is WITH, run command RZ005 Programming to reinitialise the vehicle configurations.
–Clear the faults.
–Carry out a road test (speed > 12 mph (20 km/h) and engine speed > 1200 rpm) for more than 30 seconds.
–If the fault does not recur, end the fault finding procedure.
C) If the sensor is properly connected:
–Bleed the diesel filter unit (see MR 364, Mechanics, 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.
–If the fault does not recur, end the fault finding procedure.
D) If the fault recurs:
–Check for continuity and the absence of interference resistance on the connection between:
Injection computer 32-track grey connector track A2 Track 3 of the water detection sensor
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

Check the power supply to the water detection sensor:
+ 12 V after relay track 1 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, Mechanics, 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,
hill) may causethe injection warning light to light up erratically.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

STOREDCOMBUSTION MISFIRES ON CYLINDER 1
NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the engine is started or following a road test.
Special notes:
If the fault is present, engine performance is reduced and engine instabilities may
occur.
Priority when dealing with a number of faults:
Deal with fault DF040 Cylinder 1 injector circuit first, if it is present or stored.
Check that the IMA code of injector no. 1 has been entered correctly and that it matches the code marked on the
corresponding injector.
Enter the code to the unprogrammed/incorrectly programmed injector, if necessary.
Refer to the interpretation of commands, SC002 Entering injector codes.
Check the engine compression.
Repair if necessary.
Check the valve clearance and adjust if necessary.
When dealing with several combustion misfire faults, check the conformity of the fuel by applying test 10 Diesel
fuel conformity check.
Visually inspect the return pipe of injector no. 1.
Repair if necessary.
If the fault is still present, carry out test 8 INCORRECT INJECTOR OPERATION.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.
