5. FAULT FINDING LOG
You will always be asked for this log:
– when requesting technical assistance from Techline,
– for approval requests when replacing parts with mandatory approval, and to be enclosed when returning monitored
parts on request. The log is needed for warranty reimbursement, and enables better analysis of the parts removed.
6. SAFETY INSTRUCTIONS
Safety rules must be observed during any work on a component to prevent any damage or injury:
– check the battery voltage to avoid incorrect operation of computer functions,
– use the proper tools.
7. FAULT FINDING
Stored faults are managed the same way for all sensors and actuators.
A stored fault is cleared after 128 recurrence-free starts. IMPORTANT!IMPORTANT
Any fault on a complex system requires thorough fault finding with the appropriate tools. The
FAULT FINDING LOG, which should be completed during the fault finding procedure, ensures a
record is kept of the procedure carried out. It is an essential document when consulting the
manufacturer.
IT IS THEREFORE MANDATORY TO FILL OUT A FAULT FINDING LOG EACH TIME FAULT FINDING IS
CARRIED OUT.

Adaptive idling speed correction:
Under normal warm operating conditions, the idling speed opening cycle ratio value PR091 Idling speed regulation
theoretical OCR varies between a high value and a low value to obtain the nominal idling speed.
After operating dispersion (running in, engine fouling, etc.), the opening cycle ratio value may be close to the high or
low values.
The adaptive correction PR090 Idling speed regulation programming value on the idling speed opening cycle
ratio compensates for the gradual variations in the engine's air requirement, by bringing the idling speed opening
cycle ratio back to an average nominal value.
This adjustment only takes effect if the coolant temperature is above 75 °C, 1 minute after starting the engine and
during the idle speed regulation phase.
Idling speed setpoint calculation:
The idling speed setpoint is given by parameter PR010 Idle speed regulation valve setpoint.
The idling speed regulation setpoint depends on the coolant temperature, the depollution programming, the climate
control requirements, the position of the gearbox selector, any power assisted steering action, the passenger
compartment heating resistors, the oil temperature (engine protection) and the electricity balance calculated by the
injection software (the engine speed is increased by 160 rpm maximum if the battery voltage remains below 12.7 V).
Richness management
For optimal operation of the catalytic converter, the richness must be maintained around 1.
Richness regulation is controlled by the upstream sensor. The sensor gives voltage according to the difference
between the partial oxygen pressures contained in the exhaust and a cavity filled with a reference mixture
(atmosphere).
As the partial oxygen pressure in the exhaust is representative of the richness, the voltage supplied to the computer
represents a Rich - Lean signal.
Adaptive richness correction:
In loop mode, the richness regulation corrects the injection duration in order to obtain a mixture which is as close as
possible to a richness of 1. The richness correction value PR138 Richness correction is close to 50 %, with limits
of 0 and 100 %.
The richness adaptive corrections PR143 Self-adapting richness gain and PR144 Self-adapting richness offset
are used to offset the injection mapping to centre richness regulation on 50 %.
Adaptive corrections take 50 % as an average value after computer initialisation (clearing the programming) and have
the following limit values:

1. COMPUTER REPLACEMENT OR REPROGRAMMING OPERATIONS
The system can be programmed and reprogrammed via the diagnostic socket using the RENAULT CLIP diagnostic
tool (Consult Technical Note 3585A or follow the instructions provided by the diagnostic tool).
Whenever the computer has been programmed, reprogrammed or replaced:
–Switch off the ignition.
–Start and then stop the engine (to initialise the computer) and wait 30 seconds.
–Switch the ignition back on and use the diagnostic tool to carry out the following steps:
– use command VP020 Enter VIN.
– deal with any faults declared by the diagnostic tool. Clear the computer memory.
– program the flywheel sensor target and throttle stops,
– carry out a road test followed by another check with the diagnostic tool. IMPORTANT
–Switch on the diagnostic tool (mains or cigarette lighter supply).
–Connect a battery charger (during the entire computer (re)programming procedure, the engine fan
assemblies are triggered automatically).
–Observe the engine temperature setpoints given on the diagnostic tool before (re)programming.
–Cut off all the electrical consumers (interior lighting, air conditioning, radio, etc.).
Operations to be carried out before the injection computer is reprogrammed:
Before reprogramming the injection computer, move the main Cruise control/Speed limiter switch to the rest
position. The information about the cruise control or the speed limiter displayed on the instrument panel
disappears.
Otherwise, if the main switch remains in the cruise control or speed limiter position during and after reprogramming,
the Cruise control/Speed limiter function will not be operational.
The procedure for resetting the function is as follows:
Vehicle ignition on.
– Position the main switch in rest position (the computer then detects the rest position).
– Position the switch in Cruise control position to activate the Cruise control function.
– Position the switch in Speed limiter position to activate the Speed limiter function.
IMPORTANT
It is not possible to try an injection computer coming from the Parts Department because it will no longer be
possible to use it on another vehicle.

NOTESPriority when dealing with a number of faults:
Deal with fault DF011 Sensor supply voltage no. 1 first if it is present or stored.
Special note:
–the OBD warning light is lit,
– low-speed fan is operating continuously.
– Refer to parameter PR064 Coolant temperature:
if PR064 = 120°C, short circuit to + 12 V,
if PR064 = - 40°C, short circuit to earth.
Check the cleanliness and condition of the coolant temperature sensor and its connections.
Disconnect the battery and the injection computer.
Check the cleanliness and condition of the connections.
Repair if necessary.
Use the "Universal bornier" to check the insulation and continuity of the following connections:
Injection computer, connectorB, track F2 track B2 of the coolant temperature sensor
Injection computer, connectorB, track F4 track B1 of the coolant temperature sensor
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:
12.6 kΩ ±1.1kΩ at a coolant temperature of -10°C
2200Ω ± 112Ω at a coolant temperature of 25°C
810Ω ±39Ω at a coolant temperature of 50°C
283Ω ±8Ω at a coolant temperature of 80°C
1156Ω ±3Ω at a coolant temperature of 110°C
88Ω ±2Ω at a coolant temperature of 120°C
If the fault is still present, deal with the other faults then proceed with the conformity check.
AFTER REPAIRDeal with any faults declared by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.
