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. Start the engine. Hold the engine speed at 3,000 rpm with no load (in N or P (A/T model) or
neutral (M/T model)) until the radiator fan comes
on, then let it idle.
6. Check the idle speed (see page 11-309).
7. Jump the SCS line with the HDS.
8. Connect the timing light to the service loop (white tape). 9. Aim the light toward the pointer (A) on the cam
chain case. Check the ignition timing under a no
load condition (headlights, blower fan, rear window
defogger, and air conditioner are turned off).
10. If the ignition timing differs from the specification, check the cam timing. If the cam timing is OK,
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
system work properly, and the ECM/PCM was
substituted, replace the original ECM/PCM
(see page 11-228).
11. Disconnect the HDS and the timing light.

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).

11-3), and monitor the engine coolant temperature
(ECT) sensor 1 with the HDS. Adjust the valve clearance
only when the engine coolant temperature is less than
38 °C (100 °F). 1. Remove the cylinder head cover (see page 6-36).
2. Set the No. 1 piston at top dead center (TDC). The punch mark (A) on the variable valve timing control
(VTC) actuator and the punch mark (B) on the
exhaust camshaft sprocket should be at the top.
Align the TDC marks (C) on the VTC actuator and
the exhaust camshaft sprocket. 3. Select the correct feeler gauge for the valve
clearance you are going to check.
4. Insert the feeler gauge (A) between the adjusting screw (B) and the end of the valve stem, then slide
it back and forth, you should feel a slight amount of
drag.

1. Thoroughly clean the head cover gasket and the groove.
2. Install the head cover gasket (A) in the groove of the cylinder head cover (B).
3. Check that the mating surfaces are clean and dry.
4. Apply liquid gasket, P/N 08717-0004, 08718-0001, 08718-0003, or 08718-0009, evenly to the chain
