4. The blinking frequency indicates the DTC. DTCs are
indicated by a series of long and short blinks. One
long blink equals 10 short blinks. Add the long and
short blinks together to determine the DTC. After
determining the DTC, refer to the DTC
Troubleshooting Index.
NOTE: If the DTC is not memorized, the ABS or TCS
indicator will go off for 3.6 seconds, and then come
back on.
The system will not indicate the DTC unless these
conditions are met:
• The TCS switch is not pushed.
• The brake pedal is not pressed.
• The ignition switch is turned ON (II).
• The engine is stopped.
• The SCS circuit is shorted to body ground before
the ignition switch is turned ON (II).
