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.

precautions and procedures (see page 23-14) in the SRS
section before performing repairs or service.
1. Align the front wheels straight ahead, then remove
the driver's airbag from the steering wheel (see
page 23-113).
2. Disconnect the cruise control sevresume switch
connector (A), and loosen the steering wheel nut
{B).

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.
D
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.
