How to Check for DTCs with the Honda
Diagnostic System (HDS)Symptom Troubleshooting Versus DTC
Troubleshooting
14-3
General Troubleshooting Information
A
B
A
When the powertrain control module (PCM) senses an
abnormality in the input or output system, the D
indicator (A) in the gauge control module (tach) (B) will
usually blink.
When the Honda diagnostic system (HDS) is connected
to the data link connector (DLC) (A) located under the
driver’s side of the dashboard and the SCS mode is
selected, it will indicate the diagnostic trouble code
(DTC) when the ignition switch is turned to ON (II) and
the appropriate menu is selected. If the D indicator or the malfunction indicator lamp
(MIL) has been reported on, or if a driveability problem
is suspected, follow this procedure:
1. Connect the HDS to the DLC. (See the HDS user’s manual for specific instructions.)
2. Turn the ignition switch to ON (II). Make sure the HDS communicates with the PCM. If it does not, go
to the DLC circuit troubleshooting (see page
11-204).
3. Select A/T system, and observe the DTC in the DTCs MENU on the HDS screen.
4. Record the freeze data and the on-board snapshots for all fuel and emissions DTCs and A/T DTCs.
5. If there is a fuel and emissions DTC, first check the fuel and emissions system as indicated by the DTC.
6. Clear the DTC and data.
7. Drive the vehicle for several minutes under the
same conditions as those indicated by the freeze
data, and then recheck for a DTC. If the A/T DTC
returns, go to the indicated DTC’s troubleshooting.
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.
Some symptoms will not trigger DTCs or cause the D
indicator to blink. If the MIL was reported ON or the D
indicator has been blinking, check for DTCs. If the
vehicle has an abnormal symptom, and there are no
DTCs stored, do the symptom troubleshooting. Check
the list of probable cause(s) for the symptom, in the
sequence listed, until you find the problem.

NOTE: The preferred method is to use the HDS to
retrieve the DTCs.
When the PCM senses an abnormality in the input or
output system, the D indicator (A) in the gauge control
module (tach) (B) will usually blink.
When the D indicator has been reported on, connect the
HDS to the DLC (A) located under the driver’s side of the
dashboard. Turn the ignition switch to ON (II), select
SCS mode, then the D indicator will indicate (flash) 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 HDS to the DLC. (See the HDS user’s manual for specific instructions.)
2. Turn the ignition switch to ON (II). Make sure the HDS communicates with the PCM. If it does not, go
to the DLC circuit troubleshooting (see page
11-204).
3. Select SCS mode, then observe the D indicator in the gauge control module (tach). 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.
4. Record all fuel and emissions DTCs and A/T DTCs.
5. If there is a fuel and emissions DTC, first check the fuel and emissions system as indicated by the DTC.
6. Clear the DTC and the data.
7. 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 indicated DTC’s troubleshooting.
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.

Clear A/T DTCs Procedure

General Troubleshooting Information (cont’d)

1. Connect the HDS to the DLC (A) located under the
driver’s side of the dashboard.
2. Turn the ignition switch to ON (II).
3. Make sure the HDS communicates with the PCM. If it does not, go to the DLC circuit troubleshooting
(see page 11-204).
4. Clear the DTC(s) on the HDS screen.
The OBD status shows the current system status of
each DTC and all of the parameters. This function is
used to see if the technician’s repair was successfully
completed. The results of diagnostic tests for the DTC
are displayed as:  PASSED: The on-board diagnosis is successfully completed.
 FAILED: The on-board diagnosis has finished but failed.
 NOT COMPLETED: The on-board diagnosis was running but is out of the enable conditions of the DTC. NOTE: Reset the PCM with the HDS while the engine is
stopped.
1. Turn the ignition switch to LOCK (0).
2. Turn the ignition switch to ON (II), and wait for 30 seconds.
3. Turn the ignition switch to LOCK (0), and disconnect the HDS from the DLC.
4. Do the PCM idle learn procedure (see page 11-310).
5. Start the engine with the shift lever in P or N, and warm it up to normal operating temperature (the
radiator fan comes on).
6. To verify that the problem is repaired, test-drive the vehicle for several minutes at speeds over 50 km/h
(31 mph) or under the same conditions as those
indicated by the freeze data.
Make sure to follow these points while the vehicle is
raised on a lift for the test-drive.  Disable the VSA by pressing the VSA OFF switch.
 VSA DTC’s may come on when test-driving on a lift. If the VSA DTC(s) come on, clear the DTC(s) with the
HDS.
