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 Mégane.
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.
Fault finding on the computer is carried out via the multiplex network (multiplex line).
