Where is ignition control module on a 2003 Pontiac Montana van?

The ignition control module (ICM) on a 2003 Pontiac Montana is integrated into the Powertrain Control Module (PCM). There's no separate ICM like in older vehicles. The PCM is usually located under the dashboard on the driver's side, but its exact location might vary slightly depending on the specific van's trim and options. You'll likely need to consult a repair manual specific to your year and model of Pontiac Montana to locate it precisely. A Haynes or Chilton manual would be helpful.
