(3) Turn the ignition switch to ON.
(4) Read the DTCs output from the ABS warning light and slip indicator light in the combination meter.
HINT:
- When the system is normal, the ABS warning light and slip indicator light blink at 0.25 seconds intervals (0.25 seconds on and 0.25 seconds off).
- When only 1 DTC is stored, the light outputs the same code after an interval of 4 seconds. Example: When DTC 21 is stored, the light blinks twice, turns off for 1.5 seconds, blinks once, turns off for 4 seconds, and then repeats this output pattern.
- When 2 or more DTCs are stored, the light outputs the codes with an interval of 2.5 seconds between each different code, and the output of all codes repeats after an interval of 4 seconds.
- If no code is output, inspect the TC and CG terminal circuit and the ABS warning light and slip indicator light circuits.
