3. Inspect the thrust surface {D) on each gear hub for
wear.
Inspect the cone surface (E) on each gear hub for
wear ano rougnness.
Inspect the teeth on all gears (F) for uneven wear,
scoring, galling, and cracks.
Coat the cone surface of each gear (E) with oil, andplace its synchro ring on it. Rotate the synchro ring,
making sure that it does not slip.

synchro ring against the gear evenly while
measuring the clearance. lf the clearance is less
than the service limit, replace the synchro ring andgear.

3. Install a commercially available steering wheel
puller {A) on the steering wheel (B). Free the
steering wheel from the steering column shaft by
turning the pressure bolt (C) ofthe puller.
Note these items when removing the steering
wheel:. Do not tap on the steering wheel orthesteering
column shaft when removing the steering wheel.. lf you thread the puller bolts (D) intothewheel
hub more than 5 threads, the bolts will hit the
cable reel and damage it. To prevent this, install
a pair of jam nuts 5 threads up on each puller bolt.

Bemove the steering wheel puller, then remove the
steering wheel nut and steering wheel from the
sleerino column.

How to Troubleshoot EPS DTCs
The troubleshooting flowchart procedures assume that
the cause of the problem is still present and the EPS
indicator is still on, Following the flowchart when the
EPS indicator does not come on can result in incorrect
diagnosis.
The connector iliustrations show the female terminal
connectors with a single outline and the male terminal
connectors with a double outline.
1. Ouestion the customer about the conditions when
the problem occured, and try to reproduce the
same conditions for troubleshooting. Find out
when the EPS indicator came on, such as while
turning. afterturning, when the vehicle was at a
ce rta in speed, etc.
2. When the EPS indicator does not come on during
the test drive, but troubleshooting is done based on
the DTC, check for loose connectors, poor terminal
contact. etc in the affected circuit, before you start
troubleshooting.
3. After trou bleshooting, clear the DTC and test-drive
the vehicle. Be sure the EPS indicator does not
come on.
How to Retrieve EPS DTCs
Honda PGM Tester Method:
1, With the ignition switch OFF, connect the Honda
PGM Tester (A) to the 16P data link connector (DLC)
(B) located under the dash on the driver's side of
the vehicle.
2. Turn the ignition ON (ll), and follow the prompts on
the PGM Tester to display the DTC(s) on the screen.
After determining the DTC, refer to the DTC
Troubleshooting Index.
NOTE: See the Honda PGM Tester user's manual
for specific instructions.
Service Check Signal Circuit Method:
1. With the ignition switch OFF, connect the Honda
PGM Tester (A)to the 16P data link connector (DLC)
(B) located under the dash on the driver's side of
the vehicle.
Short the SCS circuit to body ground using the
Honda PGN4 Tester.
Turn the ignition switch ON {ll).
Record the DTC.

Service Check Signal Circuit Method:
NOTE: Use this procedure when the PGM Tester
software does not match the yearlmodel vehicle you
are working on.
1. With the ignition switch OFF, connect the Honda
PGM Tester (A) to the 16P data link connector {DLC)(B) located under the dash on the driver's side of
the vehicle.
With the vehicle on the ground, set the front wheels
in the straight ahead driving position.
Short the SCS circuit to body ground using the
Honda PGM Tester.
Turn the ignition switch ON (ll). The EPS indicator
comes on for about 6 seconds. Within 4 seconds of
turning the switch ON, while the EPS indicator is on,
turn the steering wheel 45 degrees to the left from
the straight ahead driving position, and hold the
steering wheel in that position until the EPS
indicator goes off.
Within 4 seconds afterthe EPS indicator goes off,
return the steering wheel to the straight ahead
driving position and release the steering wheel.
The EPS indicator comes on again 4 seconds after
releasing the steering wheel,
Within 4 seconds after the EPS indicator comes on,
turn the steering wheel 45 degrees to the left again
and hold it in that position.
The EPS indicator goes off after 4 seconds.
4.
1.Within 4 seconds after the EPS indicator goes off,
return the steering wheel to the straight ahead
driving position again and release the steering
wheel. The EPS indicator blinks twice 4 seconds
after releasing the steering wheel, indicating that
the DTC was erased.
NOTE: If the EPS indicator does not blink twice, an
error was made in the procedure and the DTC was
not erased. Turn the ignition switch OFF, and
repeat the operation from step 3.
Turn the ignition switch OFF afterthe EPS indicator
blinks twice.
9. Disconnect the Honda PGM Tester from the DLC.
10. Perform the DTC code output operation, and be
sure that the code has been erased.

Wheel Runout Inspection
1.Raise the vehicle, and support it with safety stands
in the proper location (see page 1-5,.
Check for a bent or deformed wheel.
Set up the dial gauge as shown, and measure the
axial runout by turning the wheel.
Front and rear wheel axial runout:
Standard:
Aluminum wheel: 0-0.7 mm (0-0.03 in.)
Service limit: 2.0 mm {0.08 in.l

measure the radial runout.
Front and rear wheel radial runout:
Standard:
Aluminum wheel: 0 0.7 mm (0 0.03 io.)
Service limit: 1.5 mm {0.06 in.}
lf the wheel runout is not within the specification,
checkthe wheel bearing end play (see page 18-8),
and make sure the mating surfaces on the brake
disc and the inside of the wheel are clean.
lf the bearing end play is within the specification
but the wheel runout is more than the service limit.
replace the wheel.

shown, and measure the runout at 10 mm (0 4 in.)
from the outer edge of the disc.
Brake Disc Runout:
Service Limit: 0.10 mm (0.00tt in.l
lf the disc is beyond the service limit, refinish the
brake disc.
Max. Retinish Limit: 19.0 mm (0.75 in.)
NOTE:. lf the brakedisc is beyondtheservice limitfor
refinishing, replace it (see page 18-1 1).
. A new disc should be refinished if its runout is

safety stands in the proper location (see page 1-8).
Remove the front wheels.
2. Remove the brake pads (see page 19-11).
3. Using a micrometer, measure disc thickness at
eight points, approximately 45" apart and 10 mm
{0.4 in.) in from the outer edge of the disc.
Brake Oisc Thickness:
Standard: 20.9 21.8 mm {0.82-0.86 in.}
Max. Refinishing Limit: 19.0 mm 10.75 in.)
Brake Disc Parallelism: 0.015 mm 10.0(X)6 in.)

NOTE: This is the maximum allowable difference
between the thickness measurements
10 mm lo.it in.l
lf the smallest measurement is less than the max.
refinishing limit, replace the brake disc (see page
18-11).
lf the disc is beyond the service limit for parallelism,
refinish the brake disc with an on-car brake lathe.
The Kwik-Lathe produced by Kwik-way
Manufacturing Co. and the "Front Brake Disc
Lathe" offered by Snap-on Tools Co. are approved
for this operation.
