The system is not able to detect an ignition coil failure with the engine stopped. The test results
will be the same if the coil is faulty or not. Therefore, when testing the ignition coil make sure
that the engine makes the correct sound for a properly functioning ignition coil.
2-Injector
This is the same type of test as with ignition coil. Make sure that the injector issues a snap when
activated.
3-Fuel pump/fan/stepper
For the fuel pump, the fan and the stepper (air valve) perform a standard test. If there is a
default it twill appear as a classic default.
