  2. Short the SCS circuit to body ground using the Honda PGM Tester.
  3. Turn the ignition switch ON (II).
  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 DTC Troubleshooting Index  .
    NOTE:
    • If the DTC is not memorized, the ABS indicator will go off for 3.6 seconds, and then come back on.
    • If the ABS indicator stays on, troubleshoot for "ABS indicator does not go off" (see ABS Indicator Circuit Troubleshooting  ).

    The system will not indicate the DTC unless these conditions are met:

    • The brake pedal is not pressed.
    • The ignition switch is turned ON (II).
    • The SCS circuit is shorted to body ground before the ignition switch is turned ON (II).
