6. Gently slide the pin probe into the inspection port at the connector terminal

side. Always use the inspection port. Do not slide the probe into the connector
terminals.

Clear A/T DTCs Procedures

1. Connect the HDS to the DLC (A) located behind the driver's dashboard lower

cover.

NOTE:

For accurate result, always use the pin probe (male)

To prevent damage to the connector terminals, do
not insert test equipment probes, paper clips, or
other substitutes as they can damage the terminals.
Damaged terminals cause a poor connection and an
incorrect measurement.

Do not puncture the insulation on a wire. Punctures
can cause poor or intermittent electrical
connections.

2. Turn the ignition switch to ON (II).
3. Make sure the HDS communicates with the PCM. If it does not, go to DLC

CIRCUIT TROUBLESHOOTING .

4. Clear the DTC(s) on the HDS screen.

OBD Status

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.

How to End a Troubleshooting Session

This procedure must be done after any troubleshooting.

1. Turn the ignition switch to LOCK (0).
2. Turn the ignition switch to ON (II), and wait for 30 seconds.

NOTE:

Reset the PCM with the HDS while the engine is stopped.

3. Turn the ignition switch to LOCK (0), and disconnect the HDS from the DLC.
4. Do the PCM idle learn procedure (see ECM/PCM IDLE LEARN

PROCEDURE ).

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 31 mph (50 km/h) or under the same conditions as those
indicated by the freeze data.

Updating the PCM

Special Tools Required

Honda diagnostic system (HDS) tablet tester

Honda interface module (HIM) and an iN workstation with HDS and CM
update software

HDS pocket tester

GNA600 and an iN workstation with HDS and CM update software

NOTE:

Use this procedure when you need to update the PCM
during troubleshooting procedures.

Make sure HDS/HIM has the latest software version
downloaded from the iN (interactive network).

To ensure the latest program is installed, do a PCM
update whenever the PCM is substituted or replaced.

You cannot update a PCM with the program it already
has. It will only accept a new program.

Before you update the PCM, make sure the battery is
fully charged, and connect a jumper battery (not a
battery charger) to maintain system voltage.

Never turn the ignition switch to LOCK (0) while
updating the PCM. If you turn the ignition switch to
LOCK (0) before completion, the PCM can be damaged.
