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





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





When the D indicator has been reported on, connect the Honda PGM Tester (A) to the DLC (B) (located under the dash behind the center console). Turn the ignition switch ON (II), select Honda System, and SCS mode, then the D indicator will indicate 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:
1. Connect the Honda PGM Tester to the DLC. (See the Honda PGM Tester user's manual for specific instructions.)





2. Turn the ignition switch ON (II), select Honda System, and then SCS mode, then observe the D indicator in the gauge assembly. Code 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.
3. Record all fuel and emissions DTCs and A/T DTCs.
4. If there is a fuel and emissions DTC, first check the fuel and emissions system as indicated by the DTC (except 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).
5. Get the customer's radio anti-theft code, and write down the radio station presets.
6. Reset the memory with the Honda PGM Tester or by removing the No. 6 ECU fuse in the under-hood fuse/relay box for more than 10 seconds.
7. Drive the vehicle for several minutes at speeds over 30 mph (50 km/h), and then recheck for DTC. 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 8.
8. Enter the radio code, reset the preset stations, and set the clock.

How to Troubleshoot Circuits at the PCM

Special Tools Required
Backprobe set 07SAZ-001000A (two required)





1. Remove the dashboard lower cover (A) under the glove box (B), then you can see the PCM connectors (C).





2. Connect the backprobe adapters (A) to the stacking patch cords (B), and connect the cords to a multimeter (C).
3. Using the wire insulation as a guide for the contoured tip of the backprobe adapter, gently slide the tip into the connector from the wire side until it touches the end of the wire terminal.
4. If you cannot get to the wire side of the connector or the wire side is sealed, disconnect the connector and use the tester probe to probe the connectors from the terminal side. Do not force the probe into the connector.
