Engine Control Module Programming (Diesel)

WARNING: This page does not describe the selected car, but rather 23 other vehicles, including the 2003 Jeep Wrangler, 2003 Jeep Liberty, 2003 Jeep Grand Cherokee, 2003 Dodge Viper, and 2003 Dodge Stratus. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: If battery is disconnected, Engine Control Module (ECM) is disconnected or replaced, or Accelerator Pedal Position Sensor (APPS) has been disconnected or replaced, ECM must be programmed to match the APPS.

Ensure all components are connected. Turn ignition switch to ON position, engine off. Slowly depress accelerator pedal to the floor and release accelerator pedal to idle position one time. This ensures that APPS calibration has been programmed into the ECM. Turn ignition switch to OFF position.
