Powertrain Control Module
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. 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 PCM. The second category covers OUTPUT DEVICES
, which are components controlled by PCM.
