Engine Control Module (ECM)
NOTE:
ECM is also known as Powertrain Control Module (PCM). All references to ECM include PCM unless specified otherwise.
NOTE:
For ECM locations, see ECM LOCATION table.
Power for ECM is supplied through the EFI F-HTR fuse, located in fuse/relay block. The ECM distributes power or controls ground of various sensors, switches and solenoids for engine control.
