CIRCUIT DESCRIPTION
If the Electronic Control Unit (ECU) detects trouble, it lights the Anti-Lock Brake System (ABS) Warning Light while at the same time prohibiting ABS control. At this time, the ECU records a Diagnostic Trouble Code (DTC) in memory.
After removing the short pin of the Data Link Connector (DLC)1, connect terminals Tc and E1 of the DLC1 to make the ABS Warning Light blink and output the DTC.

Troubleshooting in accordance with the chart for each trouble symptom.
