General Troubleshooting Information
How to Check for DTCs - Service Check Signal (SCS) Method





When the Powertrain Control Module (PCM) senses an abnormality in the input or output systems, the D indicator in the gauge assembly will usually blink and/or the Malfunction Indicator Lamp (MIL) may come on. When the 16P Data Link Connector (DLC) (located under the steering column lower cover) is connected to the Honda PGM Tester and the SCS mode is selected on the PGM Tester, the D indicator will blink the Diagnostic Trouble Code (DTC) when the ignition switch is turned ON (II).
When the D indicator has been reported on, connect the Honda PGM Tester to the DLC, and select the SCS mode. Turn the ignition switch ON (II), 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. Diagnostic Trouble Code Descriptions
If the D indicator and the MIL come on at the same time, 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 radio station presets.
4. Reset the memory with the Honda PGM Tester 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 not 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 radio station presets, and set 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 passenger's side of the center lower 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.
