If that is common rail injection system most common problem is fuel pressure regulator in pump.

[pasupathy]

yes it is a common rail injection system so if we change fuel pressure regulator in pump it will be OK if so where shall i get the fuel pressure regulator

As far as i know we are sending Nissans who suffer from this to some workshop who specializing on diesel injection systems. They are changing rail pressure regulator and reprogramming ECU(i believe they just adapting new rail pressure regulator). I have done couple by myself without adaptions and they have been fine since.
Try to search for diesel specialists workshop in your area.

Hi,
my launch x431 has this function.
anyway, here's a procedure for manually clearing the learned value:

------ putting ecm into test mode II:
1. Confirm that accelerator pedal is fully released, turn ignition switch ON and wait 3 seconds.

2. then Repeat the following procedure quickly five times within 5 seconds.
-a. Fully depress the accelerator pedal.
-b. Fully release the accelerator pedal.

3. Wait 7 seconds then fully depress the accelerator pedal and keep it for approx. 10 seconds until the MI starts
blinking.

4. Fully release the accelerator pedal.
ECM has entered to Diagnostic Test Mode II (Self-diagnostic results).

------clearing the values:
5. Fully depress the accelerator pedal and keep it for more
than 10 seconds.
The emission-related diagnostic information has been erased from the backup memory in the ECM.

6. Fully release the accelerator pedal, and confirm the DTC 0000 is displayed.

7. turn ignition off for few seconds, then start engine.


hope this helps.

Does the described clearing procedure also work with other cars like opel vivaro 2.5cdti?
