PGM-FI - OBD (2013 2014 2015)
Overview
The on-board diagnostic detects failures in the emission control system. If any of the failure items in the table is detected by it, the failure is notified to the driver via the MIL in the gauge control module. For details of the failure items, refer to the DTC INDEX.
Two Drive Cycle Detection Method
When an abnormality occurs in the signal from a sensor or from another control unit in the first drive cycle, the PCM stores a Pending DTC. The MIL does not come on at this time. If the failure continues in the second drive cycle, the PCM stores a Confirmed DTC and turns on the MIL.
HDS (Honda Diagnostic System)
The data link connector (DLC) is under the driver's side of the dashboard. The DLC is used to connect the HDS or other scan tool to the vehicle for system diagnosis and troubleshooting.

The following functions are available to inspect and diagnose the PGM-FI System.
| Item | Purpose |
|---|---|
| Data list display | Display the current PCM operating value |
| Freeze data display | Display the PCM operating values at the time when the DTC stored in the PCM was detected |
| On-board snapshot display | Display the PCM operating values for a given length of time before the definitive detection of the DTC stored |
| DTC (diagnostic trouble code) display | Display a display codes that complies with the DTC standard of the SAE(society of automotive engineers) standards when the DTC is detected |
| Pending DTC display | In the system using the two drive cycle detection method, the DTC detected in the first drive cycle is displayed as a pending DTC |
| Item | Purpose |
|---|---|
| PCM Reset | Delete the PCM learning values except for those of DTC, freeze data, on-board snapshot, OBD status, idling and crank patterns |
| DTC deletion | Delete the DTC, freeze data, on-board snapshot, OBD status |
| Crank pattern learning value deration | Record and display the PCM operating values under arbitrarily-defined conditions |
| Crank pattern learning | Learn the crank pulser plate in the stop condition |
| SCS terminal short | Short the SCS terminal |
| Snapshot | Record and display the PCM operating values under arbitrarily-defined conditions |
| Inspection (function test) | Drive the actuator of the vehicle and inspect the functions |
