With SCS Mode
How to Check for DTCs with the SCS ModeWhen the PCM senses an abnormality in the input or output systems, the D indicator (A) in the gauge assembly will usually blink and/or the MIL may come on.
When the D indicator has been reported on, connect the Honda PGM Tester to the DLC. Turn the ignition switch ON (II), select Honda Systems, and then the SCS mode, then observe the D indicator.
Codes 1 through 9 are indicated by individual short blinks. Code 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. After determining the code, refer to the DTC Troubleshooting Index.
If the D indicator or the MIL has been reported on, or if a driveability problem is suspected, follow this procedure:
1. Record all fuel and emission DTCs and A/T DTCs.
2. If there is a fuel and emissions DTC, first check the fuel and emissions system as indicated by the DTC (except for DTC 70, DTC 70 means there is one or more A/T DTCs, and no problems were detected in the fuel and emissions circuit of the PCM).
3. Get the customer's radio anti-theft code, and write down the radio station presets.
4. Reset the memory by removing the No. 6 ECU (PCM) fuse in the under-hood fuse/relay box for more than 10 seconds.
5. 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 DTC Troubleshooting Index. 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, and then go to step 6.
6. Enter the radio code, reset the preset stations, and set the clock.
