How to Check for DTCs with the SCS Mode (retrieving the flash codes)

WARNING: This page is about a different car, the 2011 Honda Insight and 2010 Honda Insight. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: The preferred method is to use the HDS to retrieve the DTCs.

When the PCM senses an abnormality in the input or output system, the D indicator (A) in the gauge control module (tach) (B) will usually blink.

When the D indicator has been reported on, connect the HDS to the DLC(A) located under the driver's side of the dashboard. Turn the ignition switch to ON (II), select the SCS mode, then the D indicator will indicate (blink) the DTC.

If the D indicator and the MIL come on at the same time, or if a driveability problem is suspected, follow this procedure:

Connect the HDS to the DLC. (See the HDS user's manual for specific instructions.)
Turn the ignition switch to ON (II).
Make sure the HDS communicates with the PCM. If it does not, go to the DLC circuit troubleshooting (see DLC CIRCUIT TROUBLESHOOTING ).
Select the SCS mode, then observe the D indicator in the gauge control module (tach).
Codes 1 through 9 are indicated by individual short blinks. Codes 10 and above 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 code.

Record all fuel and emissions DTCs and A/T DTCs.
If there is a fuel and emissions DTC, first check the fuel and emissions system as indicated by the DTC.
Clear the DTC(s) and the data.
Drive the vehicle for several minutes under the same conditions as those indicated by the freeze data, and then recheck for DTCs. If the A/T DTC returns, go to the indicated DTC's troubleshooting. If the DTC does not return, there was an intermittent problem within the circuit. Make sure all pins and terminals in the circuit are tight.
