Control Unit
WARNING: This page is about a different car, the 1995 Mercury Villager. However, it is still accessible from the selected car via links, so may be relevant.
The Powertrain Control Module (PCM) is the central computer which receives data from numerous sensors and switches. The PCM processes information received and then generates output signals to control various relays, solenoids and actuators. The PCM has failure detection and self-diagnostic capability. PCM is located behind top right side of instrument panel, behind glove compartment.
NOTE:
Components are grouped into 2 categories. The first category covers INPUT DEVICES, which control or produce signals monitored by the PCM. The second category covers OUTPUT SIGNALS, which are components controlled by the PCM.
