The test module 'Ignition and injection diagnosis' checks the primary ignition signals and activation signals of the fuel injectors. The test runs automatically.
Precondition for automatic check of the primary ignition signals and activation signals of the fuel injector is the use of the multi-channel adapter MKA and the multifunction cable MFK2. A special test is used to check the operability of the adapter and of the MFK2.
At the start of the test module, the fault code memory of the Digital Engine Electronics (DME) is read out. If recorded faults are found, they should first be eliminated using the relevant test modules.
The primary-side ignition signals for cylinders 1 to 8 are picked off at the adapter boxes of the DME control unit individually for each cylinder using the MKA, displayed on the Tester as an oscilloscope measurement and then automatically evaluated.
The activation signals for the fuel injectors of cylinders 1 to 8 are measured cylinder-specifically, displayed on the Tester and then automatically evaluated.
