Reading Diagnostic Trouble Codes

NOTE: The DTC can also be read with a Honda PGM Tester.




1. Connect the SCS service connector to the service check connector (2P) located on the right side of the center console.
2. Release the parking brake.
3. Turn the ignition switch ON, but do not start the engine.








4. Record the blinking frequency of the ATTS indicator light. The blinking frequency indicates the diagnostic trouble code (DTC).

NOTE: If a DTC is not memorized, the ATTS indicator light comes back ON.

5. Turn the ignition switch OFF, and remove the SCS service connector.

NOTE: The Malfunction Indicator Lamp (MIL) will stay on after the engine is started if the SCS service connector is connected.

6. Erase the DTC.

DTC Indication Pattern
- Turn the ignition switch ON. The ATTS indicator light comes on to check the bulb.
- The ATTS control unit can memorize up to seven DTCs.
- A new DTC is not memorized when the ATTS control unit has already memorized the same DTC.
- The ATTS control unit indicates the DTC repeatedly at intervals of 4 seconds.
- If you miscount the blinking frequency or to recheck the blinking frequency, turn the ignition switch OFF, then turn it ON to cycle the ATTS indicator light again.
