Data Link Connector: Description and Operation

Circuit A14 supplies battery voltage to the cavity 16 of the data link connector. Circuit A14 originates in the Power Distribution Center (PDC) and connects to a battery fed bus bar. A 20 Amp micro fuse protects circuit A14.

A twisted pair of wires. circuits D1 and D2, from the airbag control module (ACM) connect to the data link connector. Circuit D1 connects to cavity 3 of the data link connector. Circuit D2 connects to cavity 11 of the data link connector.

Ground circuit Z12 connects to cavities 2 and 22 of the Powertrain control Module (PCM) and splices to cavities 4 and 5 of the data link connector.

Circuit D20 connects to cavity 9 of the PCM and cavity 6 of the data link connector. Circuit D20 is the SCI receive circuit for the PCM.

Circuit D21 connects to cavity 30 of the PCM and cavity 7 of the data link connector. Circuit D21 is the SCI transmit circuit for the PCM. The D21 circuit splices to the ABS module.
