WARNING: This page is about a different car, the 1997 Lexus SC 300. However, it is still accessible from the selected car via links, so may be relevant.

Each time the ignition coil(s) fire, the ECM receives a signal from 2 ignitors. If the ECM does not receive this signal, it shuts off fuel injection.
