Engine Oil Filter Replacement
Special Tool Fequired
Oil filter wrench 07HAA-PJ70100
Engine Oil Filter (3/4-turn type)
1. Remove the oil filterwiththesDecial tool.
2. Inspect the threads {A) and rubber seal (B) on the
new filter. Wipe off the seat on the engine block,
then apply a light coat of oil to the filter rubber seal.
Use only filters with a built-in bypass system.
Installthe oilfilter by hand.
After the rubber seal seats, tighten the oil filter
clockwise with the special tool.
Tighten: 3/4 turn clockwise.
Tightening torque: 12 N.m (r.2 kgf.m,8.7 lbf.ft)

5. lf 4 numbers or marks (1 to 4 or V to VVVV) are
printed around the outside of the filter, use the
following procedure to tighten the filter.
. Spin the filter on until its seal lightly seats against
the block, and note which number or mark is at
the bottom.. Tighten the filter by turning it clockwise 3
numbers or marks from the one you noted. For
example, if number 2 is at the bottom when the
seal is seated, tighten the filter until the number 1
comes around the bottom.

ECM Updating and Substitution for Testing
Special Tools Bequired
Honda Interface Module (HlM) EOS05435570
Use this procedure when you have to substitute a
known-good ECM in a troubleshooting procedure.
U pdate the ECM only if the ECN4 does not already have
the latest software loaded,
NOTE;. lMake sure the battery is fully charged before you
update the ECN4.. To prevent ECM damage during the update, do not
turn the ignition switch OFF, and do not use any of
the vehicle's electrical devices (light, horn, radio, etc. ).
How to Update the ECM
1. Turn the ignition switch ON (ll). Do not startthe
eng Ine.
2. Connect the Honda lnterface Module (HlM) to the
Data Link Connector {DLC) (A) located under the
driver's side of dashboard.
EOS05A35570
Do the ECM update procedure as described on the
HlN4 label and in the ECM update system.

How to Substitute the ECM
'1. Remove the ECM f rom the vehicle.
2. Install a known-good ECM in the vehicle.
3. Rewrite the immobilizer code with the ECM
replacement procedure from the Honda PGM
Tester. lt allows you to start the engine.
4. After completing your tests, reinstall the original
ECM and rewrite the immobilizer code with the
ECM replacement procedure on the Honda PGM
Tester again.

The i-WEC has a VTC (Variable Valve Timing Control) mechanism on the intake camshaft in addition to the usual
VTEC.
This mechanism improves fuel efficiency and reduces exhaust emissions at all Ievels of engine speed, vehicle speed.
and engine load.
The VTEC mechanism changes the valve lift and timing by using more than one cam profile.
The VTC changes the phase of the intake camshaft via oil pressure. lt changes the intake valve timing continuously.
