General Troubleshooting Information
A
A
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.
Periodically, new ECM/PCM software or new service
procedures may become available. Always check
online for the latest software or service information
relatedtotheDTCsorsymptomsyouare
troubleshooting.
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.1. Start the engine, and check the MIL (A). NOTE: If the ignition switch is turned to ON (II), and
the engine is not started, the MIL stays on for
15 20 seconds (see page 11-69). 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.
3. Turn the ignition switch to ON (II).
4. Make sure the HDS communicates with the ECM/ PCM and other vehicle systems. If it doesn’t, go to
the DLC circuit troubleshooting (see page 11-204).
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.
NOTE: Freeze data indicates the engine conditions when the first malfunction, misfire, or fuel trim
malfunction that activated the MIL 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.
6. If no DTCs are found, go to MIL troubleshooting (see page 11-203).
If the MIL did not stay on but there is a driveability
problem, do the symptom troubleshooting.
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. (cont’d)

Clear/Learn Procedure (with the HDS)
11-4Fuel and Emissions Systems
General Troubleshooting Information (cont’d)
A
The ECM/PCM stores various specific data to correct the
system even if there is no electrical power, such as
when the battery negative terminal or the No. 19
FI MAIN (15 A) fuse is 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
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 CKP
pattern. If the CKP pattern data in the ECM/PCM was
cleared, you must do the CKP pattern learn procedure.
The CKP pattern clear command erases only CKP
pattern data. This command is for repair of a misfire or
the CKP sensor.
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
(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 page
11-310); CKP pattern learn procedure;
Test-drive to set readiness codes to complete (see page
11-69).
1. Clear the DTC with the HDS while the engine is stopped.
2. Turn the ignition switch to LOCK (0).
3. Turn the ignition switch to ON (II), and wait 30 seconds.
4. Turn the ignition switch to LOCK (0), and disconnect the HDS from the DLC. 1. Reset the ECM/PCM with the HDS while the engine
is stopped.
2. Turn the ignition switch to LOCK (0).
3. Turn the ignition switch to ON (II), and wait 30 seconds.
4. Turn the ignition switch to LOCK (0), and disconnect the HDS from the DLC.
5. Do the ECM/PCM idle learn procedure (see page 11-310).
1. Connect the HDS to the data link connector (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 ECM/ PCM and other vehicle systems. If it doesn’t, go to
the DLC circuit troubleshooting (see page 11-204).
4. Select CRANK PATTERN in the ADJUSTMENT MENU with the HDS.
5. Select CRANK PATTERN LEAR NING with the HDS,
and follow the screen prompts.

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.

APP Sensor Signal Inspection
A
NOTE:
 This procedure checks the APP sensor in its fully closed position. In any other position, the APP sensor
stores DTCs which are covered in other
troubleshooting procedure.
 Check for Temporary DTCs or DTCs with the HDS before doing this procedure. If any DTCs are
indicated, troubleshoot them first, then do this
procedure.
 Press the accelerator pedal several times to check its operation. If it does not operate smoothly, check the
pedal. If you find a problem, replace the accelerator
pedal module; K20Z2 engine (see page 11-269),
K20Z3 engine (see page 11-270).
1. Connect the HDS to the data link connector (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 ECM/ PCM. If it doesn’t, go to the DLC circuit
troubleshooting (see page 11- 204).
4. Make sure the accelerator pedal is not pressed, then check the APP SENSOR in the DATA LIST with
the HDS.
 If it is 0 %, the APP sensor is OK.
 If it is not 0 %, update the ECM/PCM if it does not have the latest software, or substitute a known-
good ECM/PCM (see page 11-7), then go to step
5. 5. With the accelerator pedal not pressed, then check
the APP SENSOR in the DATA LIST with the HDS.
 If it is 0 %, the APP sensor is OK.
 If it is not 0 %, replace the accelerator pedal module; K20Z2 engine (see page 11- 269), K20Z3
engine (see page 11-270), then go to step 1.
