ALDL Connector Terminal Identification.:

Diagnostic trouble codes (DTCs) can be read with a scan tool or by jumping terminal "H" to terminal "A" of the data link connector (DLC) and counting the "ANTILOCK" lamp flashes. The terminals must be jumped for a few seconds before the DTC will begin to flash. The "ANTILOCK" lamp displays DTCs in the same manner as the malfunction indicator lamp for the fuel and emissions system.
