Data Link Connector: Description and Operation

CIRCUIT OPERATION
Circuit F39 from the Power Distribution Center (PDC) supplies battery voltage to the data link connector.

Circuit D20 connects to cavity C29 of the Powertrain Control Module (PCM). Circuit D20 is the SCI receive circuit for the PCM. Circuit D21 connects to cavity C27 of the PCM and cavity A3 of the Controller- Anti Lock Brakes. Circuit D21 is the SCI transmit circuit for the PCM. CCD Bus Circuits D1 and D2 connect to the data link connector.

Circuits Z1 and Z12 provide ground for the data link connector. Circuit Z12 also connects to cavities A31 and A32 of the PCM.
