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.
The system will not indicate the DTC unless these conditions are met:
- Set the front wheels in the straight ahead driving position.
- 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).
If the system detects an intermittent problem and stores a DTC, the EPS indicator will blink the DTC after the initial gauge assembly check.
If the system detects a fault that is still present and stores a DTC, the EPS indicator will blink twice before blinking the DTC.
5. Turn the ignition switch OFF.
6. Disconnect the Honda PGM Tester from the DLC.
