Electronic Control Module (ECM)

The Electronic Control Unit (ECU) is the "brain" of the engine control system. The ECU is located in the passenger compartment, under left side of dash to right of steering column.

The ECU senses engine operating conditions, processes input signals, and controls the various systems that affect vehicle performance.
