Special Tools Required
11-227
ECM/PCM Update
A
 Honda diagnostic system (HDS) tablet tester
 Honda interface module (HIM) and an iN workstation
with the latest HDS software version
 HDS pocket tester
 GNA 600 and iN workstation with the latest HDS software version
Any one of the above updating tools can be used.
NOTE:  Make sure the HDS/iN workstation has the latest HDS software version.
 Before you update the ECM/PCM, make sure the battery in the vehicle is fully charged, and connect a
jumper battery (not a battery charger) to maintain
system voltage.
 Never turn the ignition switch to LOCK (0) or ACC (I) during the update. If there is a problem with the
update, l eave the ignition switch to ON (II).
 To prevent ECM/PCM damage, do not operate anything electrical (headlights, audio system, brakes,
A/C, power windows, moonroof (if equipped), door
locks, etc.) during the update.
 To ensure the latest program is installed, do an ECM/ PCM update when ever the ECM/PCM is substituted or
replaced.
 You cannot update an ECM/PCM with a program it already has. It will only accept a new program.
 High temperature in the engine compartment might cause the ECM/PCM to become too hot to run the
update. If the engine was running before this
procedure, open the hood, and cool the engine
compartment.
 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, l eave the ignition
switch in ON (II) when you disconnect the HIM from
the data link connector (DLC). This will pr event ECM/
PCM damage. 1. Turn the ignition switch to ON (II), but do not start
the engine.
2. Connect the HDS to the data link connector (DLC) (A) located under the driver’s side of the dashboard.
3. Make sure the HDS communicates with the ECM/ PCM. If it doesn’t, go to the DLC circuit
troubleshooting (see page 11-204). If you are
returning from the DLC circuit troubleshooting, skip
steps 4 to 5 and clean the throttle body after
updating the ECM/PCM (see page 11- 344).
4. Select the INSPECTION MENU with the HDS.
5. Select the ETCS TEST, then select the TP POSITION CHECK, and follow the HDS screen prompts.
NOTE: If the TP POSITION CHECK indicates FAILED,
continue this procedure.
6. Exit the HDS diagnostic system, then select the update mode, and follow the screen prompts to
update the ECM/PCM.

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.
