Compressor Replacement
1. lf the compressor is marginally operable, run the
engine at idle speed, and let the air conditioning
work for a few minutes, then shut the engine off.
2. Make sure you have the anti-theft code for the radio,
then write down the frequencies for the radio's
preset buttons.

9. Installthe compressor in the reverse order of
removal, and note these items:
. Before installing the new compressor, check for
metal or other contamination in the line. Replace
any contaminated parts.. lf you're installing a newcompressor, you must
calculate the amount of refrigerant oil to be
removed from it (see page 21-6).. Replace the O-rings with new ones at each fitting,
and apply a thin coat of refrigerant oil before
installing them. Be sure to use the correct O-rings
for HFC-134a {R-134a) to avoid leakage,. Use refrigerant oil (KElHlN SP-'10) for HFC-134a
KEIHIN spiral type compressor only.. To avoid contaminatlon, do not return the oilto
the container once dispensed, and never mix it
with other refrigerant oils.. lmmediately after using the oil, reinstallthe cap
on the container, and seal it to avoid moisture
absorption.. Do not spill the refrigerant oil on the vehicle; it
may damage the paint. lf the refrlgerant oil
contacts the paint, wash it off immediately.. Charge the system (see page 21-55).. Do the engine control module (ECM) idle learn
procedure (see page 11-'139).. Enter the antitheft code for the radio, then enter
the customer's radio station presets.

back of the under-dash fuse/relay box, and remove
the fuse/relay box.
NOTE:The SRS connector is a spring-loaded lock
type (see page 23-1 1).
lnstallation
1. Installthe under-dash fuse/relay box in the reverse
order of removal and connect all connectors to the
under-dash fuse/relay box.
2. Installthe driver's dashboard lower cover.
3. Connect both the negative cable and positive cable
to the battery.
4. Enter the anti-theft code for the radio, then enter
the customer's radio station presets.
5. Confirm that all systems work properly,
6. Do the engine control module (ECM) idle learn
procedure (see page 11-139).

Installthe seat belt in the reverse order of removal,
and note these items:
. lf thethreads on the retractor mounting self-
tapping ET screw are worn out, use an oversized
self-tapping ET screw (P/N 90133-SZ4-0030)
made specifically for this application.. Check that the retractor locking mechanism
functions (see page 23-9).. Assemble the washers, collars, and bushing on
the upper and lower anchor bolts as shown.. lf the seat belt tensioner has been deployed
replace the front seat belt protector with a new
one.. Apply liquid thread lock to the anchor bolts
before reinstallation.. Before installing the anchor bolts, make sure
there are no twists or kinks in the front seat belt.. Make sure the seat belt tensioner connector is
plugged in properly.
. Reconnect the negative cable to the battery.. Enter the anti-theft code for the radio, then enter
the customer's radio station presets.
. Reset the clock.. Do the ECM/PCM idle learn procedure {see page

Precautions and Procedures
General Precautions
Please read the following precautions carefully beforeperforming airbag system service. Observe theinstructions described in this manual. or the airbags
could accidentally deploy and cause damage or injuries.
. Except when performing electrical inspections.
always turn the ignition switch OFF, disconnect the
negative cable from the battery, and wait at least 3minutes before beginning work.
NOTE: The memory is not erased even if the ignition
switch is turned OFF or the battery cables are
disconnected from the battery.. Use replacement pans which are manufactured to the
same standards and quality as the original parts. Do
not install used SRS parts from another vehicle. Useonly new pans when making SRS repairs.. Carefully inspect any SRS part before you install it.
Do not install any part that shows signs of being
dropped or improperly handled, such as dents, cracks,
or deformation.
. Before removing any SRS parts (including the
disconnection of connectors), always disconnect the
SRS connector.. Use only a digital multimeter to check the system. lf itis not a Honda multimeter, make sure its outout is 10mA (0.01A) or less when switched to the lowest value
in the ohmmeter range. A tester with a higher output
could cause accidental deployment and possible
injury.. Do not put objects on the front passenger's airbag.. The original radio has a coded theft protection circuit.
Be sure to get the customer's radio code and write
down the frequencies for the radio's preset stations
before disconnecting the battery cable.. Before returning the vehicle to the customer, enter
the radio code. then enter the customer's radio
station presets, and set the clock. Do the engine
control module (ECM) idle learn procedure (see page
11-139).

Steering-related Plecautions
Cable Reel Alignment
. Misalignment of the cable reel could cause an open in
the wiring, making the SRS system and the horns
inoperative. Center the cable reel whenever the
following is performed (see step 6 on page 23-121).
- Installation of the steering wheel- Installation of the cable reel- Installation ofthe steering column- Other steering-related adjustment or installation
. Do not disassemble the cable reel.
. Do not apply grease to the cable reel.
. lf the cable reel shows any signs of damage or
contamination. replace it with a new one. For
example, it does not rotate smoothly.
