Self-help in the ignition system
As already mentioned in the introduction to this chapter, you should entrust most work on the injection system to a professional. He has special type-specific control devices and the relevant knowledge. In case of malfunctions in the electronic control system, in order to localize the errors, it is necessary to carry out various tests in a very specific sequence: this is the only way to prevent damage to the electronic components and the resulting subsequent damage with expensive repairs. From experience, the usual knowledge of an amateur and "hobby tools" are no longer enough to reliably approach the Focus ignition system. Although in practice, defects occur here extremely rarely.
