Using SST, connect terminals TC and CG of the DLC3.
- SST: 09843-18040
Turn the ignition switch on (IG).

Observe the blinking pattern of the ABS warning and SLIP indicator lights in order to identify the DTC.

HINT:

If no code appears, inspect the TC and CG terminal circuit, and ABS warning and SLIP indicator light circuits.

Trouble Area	See procedure
TC and CG terminal circuit	Refer to TC and CG Terminal Circuit
ABS warning light circuit (Remains on)	Refer to ABS Warning Light Remains ON
ABS warning light circuit (Does not comes on)	Refer to ABS Warning Light does not Come ON
SLIP indicator light circuit (Remains on)	Refer to Slip Indicator Light Remains ON
SLIP indicator light circuit (Does not comes on)	Refer to Slip Indicator Light does not Come ON

Count the number of blinks of the ABS warning and SLIP indicator lights.
HINT:
- How to read DTCs:
  Diagnostic trouble codes are represented by the number of blinks of a warning light. For example, code 21 would be shown by 2 blinks, a pause of 1.5 seconds, and then 1 blink.
- If one code is detected:
  The light repeats the same code after a pause of 4 seconds.
- If multiple codes are detected:
  The light outputs one code after another with a 2.5-second pause between each code. When all codes have been output, there is a 4-second pause and then the light begins to output the codes again.
Check the details of the DTCs. Refer to DIAGNOSTIC TROUBLE CODE CHART .
After completing the check, disconnect terminals TC and CG of the DLC3, and turn off the display. If 2 or more DTCs are detected at the same time, the DTCs will be displayed in ascending order.

Clear the DTCs.
