2. Check for DTCs in the body electrical system with the HDS.

Is a DTC indicated?

YES - Troubleshoot the cause of the body electrical system DTC (see TROUBLESHOOTING ), and
recheck.

NO - Go to step 3.

3. Do the communication line check with the self-diagnostic procedure (see Ending the self-diagnostic

function ).

Is the word "Error" indicated on the odo/trip meter display?

YES - The gauge control module cannot receive the signal from the multiplex control unit and the
ECM/PCM. Check for an open in the WHT and RED wire (gauge control module connector terminals
No. 28 and No. 29).

NO - Go to step 4.

4. Do the gauge control module drive circuit check with the self-diagnostic procedure (see Ending the self-

diagnostic function ).

Does the temperature gauge needle sweep from the minimum position to the maximum, then return to the
minimum position?

YES - Go to step 5.

NO - Replace the gauge control module.

5. Substitute a known-good ECM/PCM (see SUBSTITUTING THE ECM/PCM ), and recheck.

Does the symptom/indication go away?

YES - Replace the ECM/PCM.

NO - Substitute a known-good gauge control module. If the symptom/indication goes away, replace the
gauge control module.

GENERAL TROUBLESHOOTING INFORMATION

INTERMITTENT FAILURES

The term "intermittent failure" means a system may have had a failure, but it checks OK now. If the
malfunction indicator lamp (MIL) on the dash does not come on, check for poor connections or loose terminals
at all connectors related to the circuit that you are troubleshooting. If the MIL was on but then went out, the
original problem may have been intermittent.

OPENS AND SHORTS

"Open" and "short" are common electrical terms. An open is a break in a wire or at a connection. A short is an
accidental connection of a wire to ground or to another wire. In simple electronics, this usually means
something won't work at all. With complex electronics (such as ECMs or PCMs) this can sometimes mean
something works, but not the way it's supposed to.

HOW TO USE THE HDS (HONDA DIAGNOSTIC SYSTEM)

If the MIL (malfunction indicator lamp) has come on

1. Start the engine, and check the MIL (A).

2. If the MIL stays on, connect the HDS to the data link connector (DLC) (A) located under the driver's side

of the dashboard.

NOTE:

If the ignition switch is turned ON (II), and the engine is not started, the
MIL stays on for 15-20 seconds (see MALFUNCTION INDICATOR LAMP
(MIL) INDICATION (IN RELATION TO READINESS CODES) ).

3. Turn the ignition switch ON (II).

4. Make sure the HDS communicates with the ECM/PCM and other vehicle system. If it doesn't go to the

DLC circuit troubleshooting (see DLC CIRCUIT TROUBLESHOOTING ).

5. Check the diagnostic trouble code (DTC) and note it. Also check the freeze data and/or on-board snapshot

data, and download any data found. Then refer to the indicated DTC'S TROUBLESHOOTING, and
begin the appropriate troubleshooting procedure.

6. If no DTCs are found, go to MIL troubleshooting (see MIL CIRCUIT TROUBLESHOOTING ).

If the MIL did not stay on

If the MIL did not stay on but there is a driveability problem, do the symptom troubleshooting.

If you can't duplicate the DTC

Some of the troubleshooting requires you to reset the ECM/PCM and try to duplicate the DTC. If the problem is
intermittent and you can't duplicate the code, do not continue through the procedure. To do so will only result in
confusion and possibly, a needlessly replaced ECM/PCM.

HDS CLEAR COMMAND

The ECM/PCM stores various specific data to correct the system even if there is no electrical power such as

NOTE:



Freeze data indicates the engine conditions when the first
malfunction, misfire, or fuel trim malfunction was detected.



The HDS can read the DTC, freeze data, on-board snapshot, current
data, and other engine control module (ECM) or powertrain control
module (PCM) data.



For specific operations, refer to the user's manual that came with the
HDS.

when the battery negative terminal or No. 6 Fl ECU (15 A) fuse are disconnected. Stored data based on failed
parts should be cleared by using the "CLEAR COMMAND" of the HDS, if parts are replaced.

The HDS has three kinds of clear commands to meet this purpose. They are DTC clear, ECM/PCM reset, and
crank (CKP) pattern clear. DTC clear command erases all stored DTC codes, freeze data, on-board snapshot,
and readiness codes. This must be done with the HDS after reproducing the DTC during troubleshooting. The
ECM/PCM reset command erases all stored DTC codes, freeze data, on-board snapshot, readiness codes, and all
specific data to correct the system except crank (CKP) pattern. If the crank (CKP) pattern data in the
ECM/PCM was cleared, you must do the crank (CKP) pattern learn procedure. The crank (CKP) pattern clear
command erases only crank (CKP) pattern data. This command is for repair of a misfire or the CKP sensor.

SCAN TOOL CLEAR COMMAND

If you are using a generic scan tool to clear commands, be aware that there is only one setting for clearing the
ECM/PCM, and it clears all commands at the same time crank (CKP) pattern learn, idle learn, readiness codes,
freeze data, on-board snapshot, and DTCs. After you clear all commands, you then need to do these procedures,
in this order: ECM/PCM idle learn procedure (see ECM/PCM IDLE LEARN PROCEDURE ); crank (CKP)
pattern learn procedure; Test-drive to set readiness codes to complete (see HOW TO SET READINESS
CODES ).

DTC CLEAR

1. Clear the DTC with the HDS while the engine is stopped.

2. Turn the ignition switch OFF.

3. Turn the ignition switch ON (II), and wait 30 seconds.

4. Turn the ignition switch OFF, and disconnect the HDS from the DLC.

ECM/PCM RESET

1. Reset the ECM/PCM with the HDS while the engine is stopped.

2. Turn the ignition switch OFF.

3. Turn the ignition switch ON (II), and wait 30 seconds.

4. Turn the ignition switch OFF, and disconnect the HDS from the DLC.

5. Do the ECM/PCM idle learn procedure (see ECM/PCM IDLE LEARN PROCEDURE ).

CRANK (CKP) PATTERN CLEAR/CRANK (CKP) PATTERN LEARN

Clear/Learn Procedure (with the HDS)

1. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.
