In SCS Mode (Retrieving the Flash Codes)

How to Check for DTCs





When the PCM senses an abnormality in the input or output systems, the D4 indicator in the gauge assembly will usually blink and/or the Malfunction Indicator Lamp (MIL) may come on. When the Data Link Connector (DLC) (located next to the driver's side kick panel) is connected to the Honda PGM Tester, the D4 indicator will blink the Diagnostic Trouble Code (DTC) when the ignition switch is turned ON (II).
When the D4 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 D4 indicator.





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. After determining the code, refer to Trouble Code Descriptions.
Diagnostic Trouble Code Descriptions
If the [D4] indicator or the MIL has been reported on, or if a driveability problem, follow this procedure:
1. Record all fuel/emissions DTCs, A/T DTCs, and freeze data.
2. If there is a fuel and emissions DTC, first check the fuel and emissions system as indicated by the DTC (except for DTC P0700), DTC P0700 means there is one or more A/T DTC, 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 numbers of the radio station presets.
4. Reset the memory by removing the BACK UP fuse in the passenger's under-dash 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 DTC returns, refer to the DTC Troubleshooting Index. If the DTC does no return, there was an intermittent problem within the circuit. Make sure all pins and terminals in the circuit are tight, then go to step 6.
6. Enter the radio code, reset the preset stations, and reset the clock.

How to Troubleshoot Circuits at the PCM

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

SRS components are located in this area. Review the SRS components locations, precautions, and procedures in SRS before performing repairs or service.





1. Pull back the carpet from the passenger's side of the center console to expose the PCM.
2. Inspect the circuit on the PCM, according to the DTC troubleshooting, with the special tools and a digital multimeter.
3. Connect the backprobe adapters (A) to the stacking patch cords (B), and connect the cords to a multimeter (C). 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 comes in contact with the terminal end of the wire.
