Fault finding – System operation
GENERAL OPERATION
The automatic transmission on this model is a DP0, which is also found on other Renault vehicles including
the Clio II, Kangoo or Megane.
The automatic transmission computer controls gear-shifting based on several parameters, among them engine
torque and the type of driving adopted by the driver.
All signals travel to the computer by wire, except for those from the injection computer, which use the multiplex
network.
Line K is used for computer diagnostics.

Reading automatic transmission configuration
The read-configuration commands (LCXXX) are used to display the current computer configuration in relation to the
equipment installed in the vehicle.
Writing automatic transmission configuration
The write-configuration commands (CFXXX) are used to configure the computer for the equipment installed in the
vehicle.
These three settings are important because they optimise transmission operation for the vehicle. If they are not
entered properly, automatic transmission operation may be impaired.Configuration reading Configuration

CONFIGURATIONS OF THE AUTOMATIC TRANSMISSION COMPUTER CF322: ENGINE TORQUE CONTROL
FUNCTION
–This function reduces engine torque when shifting gears.
–To apply this configuration, the vehicle must have the ignition on, engine stopped and gear lever in position P
or N.
–This function tells the computer what torque to apply to the engine when changing gears.
–Select configuration CF322 "Engine torque control function".
–Configure the computer WITH or WITHOUT.
–Exit fault finding mode.
–Switch off the ignition.
–Wait 15 seconds for the power-latch to end.
–re-read the configuration for confirmation.
CF314 "ELECTRONIC STABILITY PROGRAM (ESP)"
–This function limits over- or under-steering by braking certain wheels and controlling engine torque.
–To apply this configuration, the vehicle must have the ignition on, engine stopped and gear lever in position P
or N.
–This function lets the automatic transmission computer downshift for ESP adjustments.
–Select configuration CF314 "Electronic stability program (ESP)".
–Configure the computer WITH or WITHOUT.
–Exit fault finding mode.
–Switch off the ignition.
–Wait 15 seconds for the power-latch to end.
–re-read the configuration for confirmation.
CF325 "SHIFT LOCK CONNECTION FAULT FINDING"
–To apply this configuration, the vehicle must have the ignition on, engine stopped and gear lever in position P
or N.
–Select configuration CF325 "Shift lock connection fault finding".
–Configure the computer WITH or WITHOUT.
–Exit fault finding mode.
–Switch off the ignition.
–Wait 15 seconds for the power-latch to end.
–re-read the configuration for confirmation.

NOTESNone.
Run a multiplex network test (see 88B, Multiplex).
If the fault is still present, carry out fault finding on the injection system (see 17B, Petrol injection or 13B, Diesel
injection).
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the
diagnostic tool.

TORQUE CONVERTER
NOTESThere must be no present or stored faults.
This indicates the status of the torque converter.
The status should be ACTIVE when the vehicle is driven with a gear engaged.
The status should be INACTIVE when starting, changing gears, or if the vehicle is stopped.
If the status does not function as specified, apply the interpretation of fault DF016 Converter lockup solenoid
valve circuit.
If the fault is still present, contact your Techline.
AFTER REPAIRRepeat the conformity check from the start.
Make sure that shifting up and down through each gear works properly.
