This function is used to check if problems with the engine operation is related to the injectors. The tests are divided into three parts and should be performed in the following order:
Test of cylinder leakage - is performed manually with a compression tester.
Test of combustion - compare the speed of each cylinder and observe changes, the reference value is 675-725 rpm. If any cylinder have lower speed, it may be because of a damaged injector.
Test of fuel correction - the parameters shows how much the engine control unit needs to compensate the fuel amount for each cylinder, to keep the correct speed.
Hinweis:
Before the test is performed, fault codes must be erased, the engine must be warmed up and A/C turned off. If replacement of the injectors is to be performed, the engine control unit must be programmed.
