Displaying & Reading Trouble Codes

How to Check for DTCs with the PGM Tester/Scan Tool





When the Powertrain Control Module (PCM) senses an abnormality in the input or output systems, the [D5] indicator in the gauge assembly will usually blink and/or the Malfunction Indicator Lamp (MIL) will come on. When the 16P Data Link Connector (DLC) (A) (located behind the front console, between the seat heater switches) is connected to the OBD II Scan Tool or Honda PGM Tester (B) as shown, it will indicate the Diagnostic Trouble Code (DTC) when the ignition switch is turned ON (II).
If the [D5] indicator or the MIL has been reported on, or if a driveability problem is suspected, follow this procedure:
1. Connect the OBD II Scan Tool (conforming to SAE J1978) or Honda PGM Tester to the 16P DLC. (See the OBD II Scan Tool or Honda PGM Tester user's manual for specific instructions. If you are using the Honda PGM Tester, make sure it is set to the SAE DTC type.)
2. Turn the Ignition switch ON (II), and observe the DTC on the screen.
3. Record all fuel and emissions DTCs, A/T DTCs, and freeze data.
4. 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.
5. Get the customer's radio anti-theft code, and write down the radio station presets.
6. Reset the memory with the PGM Tester or by removing the BACK UP fuse in the passenger's under-dash fuse/relay box for more than 10 seconds.
7. Calibrate the engine idle control system in the PCM, 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 8.
8. Enter the radio code, reset the preset stations, and set the clock.

How to Check for DTCs





When the PCM senses an abnormality in the input or output systems, the [D5] indicator (A) in the gauge assembly (B) will usually blink and/or the MIL may come on. When the 16P Data Link Connector (DLC) (located behind the front console, between the seat heater switches) is connected to the Honda PGM Tester, the D5 indicator will blink the Diagnostic Trouble Code (DTC) when the ignition switch is turned ON (II).
When the [D5] indicator has been reported on, connect the PGM Tester to the DLC (16P). Turn the ignition switch ON (II), select Honda Systems, and then the SCS mode, then observe the [D5] indicator. If a PGM Tester is not available, jump DLC terminal 1 (BRN) to terminal 12 (BLK), then turn the ignition switch ON (II) and observe the [D5] 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 D5 indicator or the Malfunction Indicator Lamp (MIL) has been reported on, or if a driveability problem is suspected, follow this procedure:
1. Record all fuel and 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 70). DTC 70 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 by removing the BACK UP fuse in the passenger's under-dash fuse/relay box for more than 10 seconds.
5. Calibrate the engine idle control system in the PCM, 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. Re-enter the radio code, reset the preset stations, and set the clock.
