It is fascinating how fast there have been technological advancement all around the globe since the very dawn of industrial revolution. Though it is hard to believe but it is a fact that today’s automobile has more computer technology than the first Lunar space module! An ECM or an engine control modulator is an advanced piece of technology on board a car which monitors and regulates engine functions, emission gasses and also it optimizes engine performance and fuel consumption to a huge extent. The Dodge Caravan ecm is mounted in between the battery and the nearest headlight within the engine compartment in most of the versions of the Dodge Caravans. This hugely varies on the year of the van and also on the type of module that particular version uses. A faulty module should be fixed as soon as possible as it can lead to prolonged problems.

Generally the systems controlled by the ECM include fuel delivery, EGR (exhaust gas re-circulation), evaporative system, air management, TCC (torque converter clutch) and also spark timing. It is constantly updated with data (voltage signals) from the sensors (input) about engine operation. The sensors are basically variable resistors which modifies a voltage to or from the ECM.

  • The fifth step is installing the replacement control module and then connecting its lower and upper bolts and electrical connectors.
  • The sixth step is re-installing the headlight housing with its electrical connectors and retaining the bolts after that.
