- Start engine.

- Observe DVOM when voltage is allowed to stabilize.

- Lightly tap on ICM to simulate road shock.

- Wiggle ICM connector and Camshaft Position (CMP) sensor connectors.

- A sudden change in voltage indicates a fault.

- Is a fault indicated?

Yes -- Disconnect and Inspect connectors. If connector and terminals are good, remove breakout box, reconnect all components and Refer to Ignition Systems for Distributor Ignition (DI) Diagnostics.
