STOREDACCELEROMETER CIRCUIT
NOTESPriorities when dealing with a number of faults :
DF001 Coolant temperature sensor circuit,
DF002 Air temperature sensor circuit,
DF098 Fuel temperature sensor circuit,
DF003 Atmospheric pressure sensor circuit.
A fault on these sensors could lead to incorrect fault finding on the accelerometer.
Conditions for applying fault finding procedures to stored faults:
The fault is present with the engine idling.
Check the conformity of the injectors fitted to the vehicle in relation to the type of vehicle and engine number
(low, high or very high pressure injector).
Check the condition and connection of the accelerometer connector.
Repair if necessary.
Check the connection and condition of the brown 48-track connector B of the computer and check the sensor
shielding on track K1.
Repair if necessary.
Check the insulation, continuity and the absence of interference resistance on the following connections:
Sensor connector track 1 Track F1 computer connector B
Sensor connector track 2 Track G1 computer connector B
Repair if necessary.
Check that the C2I is correctly entered on the computer.
Check that the accelerometer is secured on the engine.
Disconnect and reconnect the accelerometer sensor to accomplish fast programming.
Carry out a road test followed by another check with the diagnostic tool.
If the fault is still present, replace the accelerometer.

NOTESSpecial notes:
If DF130, the engine may stop with the level 1 and 2 warning lights illuminated along
with the message Faulty injection.
Conditions for applying fault finding procedures to stored faults:
The fault is present with the engine running.
Check the connection and condition of the of the fuel flow actuator connector (IMV), and repair it if necessary.
Measure the resistance between tracks 1 and 2 of the flow actuator.
Replace the flow actuator if the resistance is not 5.3 Ω ± 0.5 Ω at 20°C.
Check the connection and condition of the computer 48-track brown connector B.
Repair if necessary.
Check the insulation, continuity and the absence of interference resistance on the following connection:
Computer connector B track M4 track 1 fuel flow actuator
Repair if necessary.
Check that there is fuel present in the tank and that it is correct. Run Test 13 Diesel fuel conformity check.
