Crankshaft Inspection
1. Remove the crankshaft from the engine block(see page 7-13).
2. Clean the crankshaft oil passages with pipe cleaners or suitable brush.
3. Clean the keyway and the threads, and check for damage.
4. Measure the out-of-round at the middle of each rod and main journal in two places. The difference
between measurements on each journal must not
be more than the service limit.
5. Measure the taper at the edges of each rod and the main journal. The difference between
measurement on each journal must not be more
than the service limit. 6. Place the V-blocks on a flat surface.
7. Check the total runout with the crankshaft
supported on V-blo cks.
8. Measure the runout on all main journals. Rotate the crankshaft two complete revolutions. The
difference between measurements on each journal
must not be more than the service limit.

When the PCM determines that the vehicle is climbing a hill in D, and S with automatic shift mode, the system extends
the engagement area of 2nd, 3rd, and 4th gears to prevent the transmission from frequently shifting between 2nd and
3rd gears, between 3rd and 4th gears, and between 4th and 5th gears. Then PCM does this so the vehicle can run
smoothly and have more power when needed.
NOTE: Shift commands stored in the PCM between 2nd and 3rd gears, between 3rd and 4th gears, and between 4th
and 5th gears, enable it to automatically select the most suitable gear according to the magnitude of a gradient.
When the PCM determines that the vehicle is going down a hill in D, and S with automatic shift mode, the upshift
speed from 4th to 5th gear, from the 3rd to 4th gear, and from 2nd to 3rd gear (when the throttle is closed) becomes
higher than the set speed for flat road driving to extend 4th gear, 3rd gear, and 2nd gear driving area. This, in
combination with engine braking from the deceleration lock-up, achieves smooth driving when the vehicle is
descending. There are three descending modes with different 4th gear driving areas, 3rd gear driving areas, and 2nd
gear driving areas according to the magnitude of a gradient stored in the PCM. When the vehicle is in 5th gear or 4th
gear, and you are decelerating when you are applying the brakes on a steep hill, the transmission will downshift to
lower gear. When you accelerate, the transmission will then return to a higher gear.

1. Raise the vehicle, and support it with safety stands
in the proper locations (see page 1-11).
2. Remove the wheels.
3. Install suitable flat washers (A) and the wheel nuts. Tighten the nuts to the specified torque to hold the

4. Attach the dial gauge. Place the dial gauge against the hub flange.
5. Measure the bearing end play while moving the brake disc inward and outward.
6. If the bearing end play measurement is more than the standard, replace the wheel bearing or the hub
bearing unit. 1. Raise the vehicle, and support it with safety stands
in the proper locations (see page 1-11).
2. Check for bent or deformed wheels.
3. Set up the dial gauge as shown, and measure the axial runout by turning the wheel.

from the outer edge of the brake disc. 7. If the brake disc is beyond the service limit, refinish
the brake disc with a Honda-approved
commercially available on-car brake lathe.
NOTE: If the brake disc is beyond the service limit for refinishing, replace it (see page 19-21).
 If the brake disc is replaced with a new one, check the new disc for runout. If the new disc is
out of specification, refinish the disc.

NOTE: If the brake disc is stuck to the front hub,
thread two 8 x 1.25 mm bolts (C) into the brake disc
to push it away from the front hub. Turn each bolt
90 degrees at a time to prevent the brake disc from
binding.
7. Install the brake disc in the reverse order of removal.

Go to step 2.
Go to audio disc does not load (see page
23-61).
2. Insert the audio diagnostic CD (T/N: 07AAZ- SDBA100) in the navigation unit or audio unit.
The original disc is faulty, or has an
unreadable format.
 With navigation: Replace the navigation unit (see page 23-155).
 Without navigation: Replace the audio unit (see page 23-80).  Diagnostics CD 07AAZ-SDBA100

1. Confirm the vehicles tires are properly inflated.
2. Check the clients CD for scratches, fingerprints, and marks.
NOTE: Do this following test with audio unit bass
and treble set to clients listening performance.
When comparing to known-good vehicles,
comparison should be performed on same model
and trim level.
3. Test drive to identify when the CD skips. The diagnostics CD (T/N: 07AAZ-SDBA100) can be used
if clients CD is not available. Use tracks 10 to 12.
Go to step 4.
Operation is normal.
4. Compare the clients CD that skips in a known-good vehicle under the same conditions.
Operation is normal.
Go to step 5.
NOTE: Do this following test with vehicle parked
and engine running.
