Remove the camshaft holders. Measure the widest portion of plastigage on each journal:


If the camshaft-to-holder clearance is within the service limits, go to step 10.

If the camshaft-to-holder clearance is beyond the service limit, and the camshaft has been replaced, replace the cylinder head.

If the camshaft-to-holder clearance is beyond the service limit, and the camshaft has not been replaced, go to step 9.


Camshaft-to-Holder Oil Clearance

1.

From the INSPECTION MENU of the HDS, select Fuel Pump ON.


NOTE: Pending or Confirmed DTC may be set during this procedure. Check for DTCs, and clear them as needed.


2.

Turn the ignition switch to LOCK (0).


49. Fuel Line Leak Check

1.

Turn the ignition switch to ON (II) (but do not operate the starter motor). The fuel pump runs for about 2 seconds, and fuel pressure rises. Repeat this two or three times, then make sure there are no fuel leaks.


50. Radiator Coolant - Replacement

1.

Follow the chart and pour coolant into the radiator up to the base of the filler neck.


NOTE:

Use Honda Long Life Antifreeze/Coolant Type 2, and if necessary add Honda Extreme Cold Weather Antifreeze/Coolant Type 2 (concentrate). Using a non-Honda coolant can result in corrosion, causing the cooling system to malfunction or fail.

Honda Long Life Antifreeze/Coolant Type 2 is a mixture of 50 % antifreeze and 50 % water. Honda Extreme Cold Weather Antifreeze/Coolant Type 2 is a 100 % concentration coolant. Do not add water to either coolant.

If the vehicle is regularly driven in very low temperatures (below -22 °F ( -30 °C)), a 60 % concentration of coolant should be used.

51. Engine Cover

1.

Install the engine cover.


52. Tire and Wheel-Installation, Front Right

mminmuan

1.

Install the right front wheel.


NOTE: Before installing the wheel, clean the mating surfaces between the brake disc and the inside of the wheel.


53. Splash Shield

1.

Install the splash shield (A).


54. Warm Up The Engine

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.


55. Idle Speed - Inspection

1.

Check the idle speed without electrical load: headlights, blower fan, radiator fan, and air conditioner off.


Idle speed should be:


750±50 rpm (in neutral)


2.

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).


Idle speed should be:


750±50 rpm (in neutral)


NOTE: If the idle speed is not within specification, do the ECM idle learn procedure. If the idle speed is still not within specification, go to symptom troubleshooting.


56. CKP Pattern Clear/CKP Pattern Learn

1.

Select CRANK PATTERN in the ADJUSTMENT MENU with the HDS.


2.

Select CRANK PATTERN CLEAR, and clear the CKP pattern.


3.

Select CRANK PATTERN LEARNING with the HDS, and follow the screen prompts.


57. Ignition Timing - Inspection


1.

Jump the SCS line with the HDS.


2.

Connect the timing light to the service loop (white tape).



3.

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).


Ignition Timing

8±2 ° BTDC (RED mark (B)) at idle


4.

If the ignition timing differs from the specification, check the cam timing. If the cam timing is OK, update the ECM if it does not have the latest software, or substitute a known-good ECM, then recheck. If the system works properly, and the ECM was substituted, replace the original ECM.


5.

Disconnect the HDS and the timing light.
