ECM/PCM CONNECTOR B (44P)
1. Connect the Honda Diagnostic System (HDS) to the
data link connector (DLC) (see step 2 on page 11-3).
2. Turn the ignition switch to ON (II).
3. Make sure the HDS communicates with the vehicle and the engine control module (ECM)/powertrain
control module (PCM). If it does not communicate,
troubleshoot the DLC circuit (see page 11- 204).
4. Check for DTCs (see page 11-3). If a DTC is present, diagnose and repair the cause before continuing
with this test.
5. Disconnect the alternator 4P connector.
6. Start the engine, and turn on the headlights to high beam.
7. Measure the voltage between alternator 4P connector terminal No. 2 and the positive terminal
of the battery.
Go to step 11.
Go to step 8.
8. Jump the SCS line with the HDS, then turn the ignition switch to LOCK (0).
NOTE: This step must be done to protect the ECM/
PCM from damage.
9. Disconnect ECM/PCM connector B (44P). 10. Check for continuity between ECM/PCM connector
terminal B41 and body ground.
Repair short to ground in the wire between
alternator 4P connector terminal No. 2 and ECM/
PCM connector terminal B41.
Update the ECM/PCM if it does not have the
latest software (see page 11-227), or substitute a
known-good ECM/PCM (see page 11-7), then
recheck. If the symptom/indication goes away with
a known-good ECM/PCM, replace the original ECM/
PCM (see page 11-228).
11. Jump the SCS line with the HDS, then turn the ignition switch to LOCK (0).
NOTE: This step must be done to protect the ECM/
PCMfromdamage.
12. Disconnect ECM/PCM connector B (44P).

DTC Troubleshooting (cont’d)
36. Monitor the OBD STATUS for DTC P050B in the
DTCs MENU with the HDS.
If the ECM/PCM was updated,
troubleshooting is complete. If the ECM/PCM was
substituted, replace the original ECM/PCM
(see page 11-228). If any other Temporary DTCs or
DTCs were indicated in step 35, go to the indicated
DTC’s troubleshooting.
If the screen indicates FAILED, check for poor
connections or loose terminals at the CKP sensor,
the throttle body, the MAF/IAT sensor, ECT
sensor 1, ECT sensor 2, and the ECM/PCM. If the
ECM/PCM was updated, substitute a known-good
ECM/PCM (see page 11-7), then go to step 33. If the
ECM/PCM was substituted, go to step 1. If the
screen indicates EXECUTING, keep idling until a
result comes on. If the screen indicates OUT OF
CONDITION, go to step 33. NOTE:
 Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general
troubleshooting information (see page 11-3).
 If any high current load accessories are installed, this DTC can be set.
 If DTC P16BB and/or P16BC is stored at the same time as DTC P0562, troubleshoot DTC P16BB and/or P16BC
first, then recheck for DTC P0562.
1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Start the engine.
4. Check under these conditions: A/Con
 Temperature control at maximum cool
 Blower fan at maximum speed
 Rear window defogger on
 Headlights on high beam
5. Hold the engine speed at 2,000 rpm (A/T in P or N, M/T in neutral) for 1 minute.
6. Check for Temporary DTCs or DTCs with the HDS.
Replace the alternator (see page 4-34), then
go to step 7.
Intermittent failure, the system is OK at this
time. Check for poor connections or loose terminals
at the alternator and the under-hood fuse/relay box,
and check the battery performance (see page
22-67).Charging System Low Voltage

Procedure
11-31011-310Idle Control System
Idle Speed Inspection (cont’d) ECM/PCM Idle Learn Procedure
4. Start the engine. Hold the engine speed at
3,000 rpm without load (A/T in P or N, M/T in
neutral) until the radiator fan comes on, then let it
idle.
5. Check the idle speed without load conditions: headlights, blower fan, radiator fan, and air
conditioner off.
6. Let the engine idle for 1 minute with high electric load (A/C switch on, temperature set to max cool,
blower fan on high, and headlights on high beam).
NOTE: If the idle speed is not within specification,
dotheECM/PCMidlelearnprocedure(seepage
11-310). If the idle speed is still not within
specification, go to the symptom troubleshooting.
7. Reconnect the EVAP canister purge valve connector. The idle learn procedure must be done so the ECM/PCM
can learn the engine idle characteristics.
Do the idle learn procedure whenever you do any of
these actions:
 Replace the ECM/PCM.
 Reset the ECM/PCM.
 Update the ECM/PCM.
 Replace or clean the throttle body.
 Disassemble the engine or the transmission.
NOTE: Erasing DTCs with the HDS does not require you
to do the idle learn procedure.
1. Make sure all electrical items (A/C, audio, lights, etc.) are off.
2. Reset the ECM/PCM with the HDS.
3. Turn the ignition switch to ON (II), and wait 2 seconds.
4. Start the engine. Hold the engine speed at 3,000 rpm without load (A/T in P or N, M/T in
neutral) until the radiator fan comes on, or until the
engine coolant temperature reaches 90 °C (194 °F).
5. Let the engine idle for about 5 minutes with the throttle fully closed.
NOTE: If the radiator fan comes on, do not include
its running time in the 5 minutes.
