PRESENTCOOLANT TEMPERATURE SENSOR CIRCUITCO.1: Open circuit or short circuit to + 12 volts
CC.0: Short circuit to earth
NOTESSpecial notes:
If DF001 is present, the fan assembly is activated at low speed (fan assembly 1). If fan
assembly 1 is faulty, fan assembly 2 is activated for vehicles fitted with air conditioning.
Check the connection and condition of the 4-track connector for the coolant temperature sensor.
Repair if necessary.
Check the connection and condition of the computer 48-track brown connector B.
Repair if necessary.
Measure the resistance of the coolant temperature sensor between tracks 2 and 3.
Replace the coolant temperature sensor if the resistance is not 2252 Ω ± 112.16 Ω at 25°C.
Check the insulation, continuity and the absence of interference resistance on the following connections:
Sensor connector track 2 Track H3 computer connector B
Sensor connector track 3 Track H2 computer connector B
Sensor connector track 1 Instrument panel
Sensor connector track 4 Instrument panel
Repair if necessary.

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.
