These computers coordinate fuel delivery, ignition timing, and transmission shifting, so any disruption can manifest as a no\u2011start condition, erratic idle, or unexpected warning lights. This guide walks you through what the modules do, where they sit, how long a dealer\u2011booked relearn or replacement typically takes, and what you can expect when you choose a Flagship One replacement. By the end, you\u2019ll understand the diagnostic clues, the required factory procedures, and practical steps to keep your Caravan\u2019s PCM and ECM healthy.<\/p>\n<\/div>\n<div class=\"info-section\">\n<h2>What the PCM Does in a 2002 Dodge Caravan<\/h2>\n<p>In the 2002 Dodge Caravan, the powertrain control module (PCM) and engine control module (ECM) act as the vehicle\u2019s brain, interpreting sensor data to regulate fuel injection, spark timing, and transmission shift points. They also store diagnostic trouble codes and communicate with the scan tool. A malfunction can cause loss of driveability, especially under load, because the computer can no longer command the engine or transmission correctly. Maintaining proper voltage and grounding is essential, as the modules rely on a stable electrical environment.
