Powertrain Control Module (PCM)

The PCM is the only module on the SCP communication network. If one of the bus wires becomes shorted to ground or voltage, or if some but not all termination resistors are lost, communications can continue. Check circuits P/LB and T/O between the PCM 0140-175 and the DLC D-01. Total resistance values must not be more than 5 ohms. If the resistance is more than 5 ohms there is an open circuit in the SCP network, damage to the DLC D-01, damage to the PCM 0140-175, or a problem in the in-line connector.
