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)

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.
