OPERATIONS FOR REPLACING THE INJECTORS
– Switch on the vehicle + after ignition feed after replacing the part.
Carry out resetting using command RZ033 Richness regulation programming.
– Switch off the ignition.
A power latch is necessary to save the reset data.
– Switch on the vehicle + after ignition feed and check the values of the following parameters:
PR624 Richness regulation programming offset
PR625 Richness regulation programming gain
– Test the injectors using the following commands:
AC005 Cylinder 1 injector
AC006 Cylinder 2 injector
AC007 Cylinder 3 injector
AC008 Cylinder 4 injector.
OPERATIONS OF REPLACING THE CAMSHAFT DEPHASER SOLENOID VALVE
– Switch on the vehicle + after ignition feed.
– Reset to zero using command RZ001 Fault memory.
– Start the engine and allow the engine to idle for at least 60 seconds.
– Switch off the engine.
– Wait for the end of the power-latch phase and switch on the vehicle + after ignition.
– Check that ET845 Camshaft dephaser s.v.* programming is PERFORMED.
