Circuit Description

If ABS/TRAC ECU detects a system malfunction, ABS/TRAC ECU illuminates ABS warning light while at the same time prohibiting ABS control. At this time, ABS/TRAC ECU records a DTC in memory. Connecting terminals Tc and E₁ of DLC1 or DLC2 causes ABS warning light to blink and output a DTC. On 2000 models, terminals Tc and CG of DLC3 may also be used. See Figure.
