Control Unit
The Powertrain Control Module (PCM) is a computer, which receives data from numerous sensors, switches and relays. The PCM cali-brates information received and then generates output signals to control various relays, solenoids and actuators. The PCM has failure detection and self-diagnostic capability.
On 1.8L and 2.0L A/T, PCM is integrated with the Transaxle Control Module (TCM). On all models, PCM is located on the center console behind the kick panel.
NOTE:
Components are grouped into 2 categories. The first category covers INPUT DEVICES, which control or produce voltage signals monitored by the control unit. The second category covers OUTPUT SIGNALS, which are components controlled by the control unit.
