PROCEDURE
Diagnostic Trouble Codes (DTC)'s can be displayed by jumping terminals "A" and "H" of the Data Link Connector and observing the flashing of the "ANTILOCK" warning light. The terminals must be jumped for a few seconds before the code will begin to flash. The "ANTILOCK" light displays codes similar to the "SERVICE ENGINE SOON" or "MIL" light for the fuel and emissions system.
