Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Electronic Control Module
The Electronic Control Module (ECM) is located behind right side of instrument panel. Information from several sensors is received and processed by the ECM to produce proper pulse duration for each injector, correct idle speed and proper spark timing.
The ECM performs calculations to control the following engine operating conditions: engine start, engine flooding, engine running, fuel enrichment during acceleration, lean fuel mixture during deceleration, battery voltage correction, and fuel cut-off.
