When the PCM senses an abnormality in the input or
output system, the D indicator (A) in the gauge
assembly (B) will usually blink.

When the D indicator has been reported on, connect the
HDS to the DLC (A) (located under the dash behind the
center console). Turn the ignition switch ON (II), select
SCS mode, then the D indicator will indicate (blink) 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 ON (II), select SCS mode,

then observe the D indicator in the gauge assembly.
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.

3. Record all fuel and emissions DTCs and A/T DTCs.

4. If there is a fuel and emissions DTC, first check the

fuel and emissions system as indicated by the DTC
(except DTC 70, DTC 70 means there is one or more
A/T DTCs, and no problems were detected in the
fuel and emissions circuit of the PCM).

5. Clear the DTC and data.

6. Drive the vehicle for several minutes under the

same conditions as those indicated by the freeze
data, and then recheck for DTC. 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.

1. Remove the dashboard lower cover (A) under the

glove box (B), then you can see the PCM
connectors (C).

2. Connect the backprobe adapters (A) to the stacking

patch cords (B), and connect the cords to a
multimeter (C).

3. 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
touches the end of the wire terminal.

4. If you cannot get to the wire side of the connector

or the wire side is sealed, disconnect the connector
and use the tester probe to probe the connectors
from the terminal side. Do not force the probe into
the connector.

1. Connect the HDS to the DLC.

2. Turn the ignition switch ON (II).

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

1. Connect the HDS to the DLC.

2. Turn the ignition switch ON (II).

3. Reset the PCM with the HDS.

4. Turn the ignition switch OFF.

5. Turn the ignition switch ON (II), and wait

30 seconds.

6. Turn the ignition switch OFF, and disconnect the

HDS from the DLC.

7. Do the PCM idle learn procedure (see page 11-349).

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
finished. The results of diagnostic tests for the DTC are
displayed as:

• PASSED: On Board Diagnosis is successfully finished.
• FAILED: 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.

PCM Updating and Substitution for Testing

How to Update PCM

How to Substitute the PCM

Special Tools Required

14-11

A

Honda Interface Module (HIM) EQS05A35570

Use this procedure when you have to substitute a
known-good PCM in a troubleshooting procedure.
Update the PCM only if the PCM does not already have
the latest software loaded.

Do not turn the ignition switch OFF while updating the
PCM. If you turn the ignition switch OFF, the PCM can
be damaged.

NOTE:

• To ensure the latest program is installed, update a

PCM 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 vehicle’s

battery is fully charged.

• To prevent PCM damage, do not operate any

electrical system; audio system, brakes, air
conditioning, power windows, moonroof, and door
locks, during the update.

• If you need to diagnose the Honda interface module

(HIM) because the HIM’s red (

3) light came on or

was flashing during the update, leave the ignition
switch in the ON (II) position when you disconnect the
HIM from the DLC. This will prevent PCM damage.

1. Turn the ignition switch ON (II). Do not start the

engine.

2. Connect the Honda interface module (HIM) to the

DLC (A) located under the dash behind the center
console.

3. Update the PCM according to the procedures

described on the HIM label. If the software in the
PCM is the latest, replace the PCM.

1. Connect the HDS to the DLC.

2. Turn the ignition switch OFF.

3. Jump the SCS line with the HDS.

4. Remove the PCM, and install a known-good PCM.

5. Open the SCS with the HDS.

6. Turn the ignition switch ON (II).

NOTE: If DTC: P0630 ‘‘VIN Not Programmed or
Mismatch’’ is stored at this time, ignore it and
continue this procedure.

7. Input the VIN to the PCM with the HDS.

8. Rewrite the immobilizer code with the PCM

replacement procedure in the HDS; it allows you to
start the engine.

9. Reset the PCM with the HDS.

10. Do the PCM idle learn procedure (see page 11-349).

11. Do the CKP pattern learn procedure.

12. After completing your test, reinstall the original

PCM and rewrite the immobilizer code with the
PCM replacement procedure in the HDS again.
