NOTESNone.
Check the conformity of the injectorsfitted to the vehicle in relation to the type of vehicle and engine number (low,
high or very high injector pressure).
Check that the C2I is correctly entered on the computer.
Check the accelerometer shielding on track K1 of the brown 48-track connector B of the computer.
Check that the accelerometer is secured on the engine.
After retightening the accelerometer, it is essential to clear the pressure regulation adaptives using command
RZ004 Pressure regulation adaptives.
Disconnect and reconnect the accelerometer sensor to accomplish fast programming.
