NOTE:
This system is used on vehicles with the MPG engine only. Other vehicles use a Bosch Electronic Ignition System. See appropriate article in this section.
The Volvo Computer Controlled Electronic Ignition System consists of a Volvo breakerless distributor, an electronic control unit, ignition coil, ignition switch and a vacuum signal microswitch.
The distributor contains no vacuum or centrifugal advance mechanisms. The rotor and armature are a single unit. A Hall Effect sending unit (pick-up coil) provides engine speed signals to the electronic control unit. The distributor also consists of necessary wiring and distributor cap.
