Observe the blinking pattern of the ABS warning light and read the multi-information display in order to identify the DTC

HINT

If no code appears, inspect the TC and CG terminal circuit, and ABS warning and VSC warning (master caution indicator light and multi-information display) light circuits

TROUBLE AREA CHART

Trouble Area	See Procedure
TC and CG terminal circuit	TC AND CG TERMINAL CIRCUIT
ABS warning light circuit (Remains on)	ABS WARNING LIGHT REMAINS ON
ABS warning light circuit (Does not come on)	ABS WARNING LIGHT DOES NOT COME ON
VSC warning light (Master caution indicator light and multi-information display) circuit (Remains on)	VSC WARNING LIGHT REMAINS ON
VSC warning light (Master caution indicator light and multi-information display) circuit (Does not come on)	VSC WARNING LIGHT DOES NOT COME ON

As an example, the illustration below shows the blinking patterns of the normal system code and trouble codes 11 and 21 for the ABS warning light, and display of normal system code and trouble code 43 for the VSC on the multi-information display.
