Jeigu kam idomu, kaip patikrinti purkstukus:

1)

Read the measured value blocks 72 - 77.

3 values per measured value block appear there (for 300 bar, 600 bar, 1000 bar).

Should the values be higher than minus -45 ms (example - 60ms) or

on digit 2 be

higher than minus -15 ms (e.g. 20ms),

the needle attachment is worn and the injector is incorrect. To avoid repeat repairs, replace all 6 injectors.

 Observe the algebraic sign (minus) in measured value block 72-77 !!!


2)


vcds go to address 01 measured values below
