Distributor Ignition (Di)

WARNING: This page is about a different car, the 1995 Ford Pickup, 1995 Ford F-Super Duty, and 1995 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

All engines, except those with distributorless ignition systems, use the DI system (formerly Thick Film Ignition-IV (TFI-IV) system). The DI system components consist of ICM, distributor, CMP (Hall Effect) sensor and "E" core ignition coil. The DI distributor is a gear-driven, die-cast unit. A Hall Effect stator assembly is used to trigger ignition coil. This distributor does not use conventional centrifugal/vacuum advance mechanisms. The ICM is mounted to right inner fenderwell.

Distributor uses a Hall Effect switch mechanism to switch primary voltage and send a Profile Ignition Pick-Up (PIP) signal to PCM. The PCM uses PIP input signal to produce a Spark Output (SPOUT) signal, which is sent to the ICM to trigger coil secondary voltage discharge.
