SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
The Acura RSX SRS includes a driver’s airbag in the steering wheel hub, a passenger’s airbag in the dashboard above
the glove box, seat belt tensioners in the front seat belt retractors, seat belt buckle tensioners in the front seat belt
buckles, and side airbags in the front seat-backs. Information necessary to safely service the SRS is included in this
Service Manual. Items marked with an asterisk ( ) on the contents page include or are located near SRS components.
Servicing, disassembling, or replacing these items require special precautions and tools, and should be done only by
an authorized Acura dealer.
To avoid rendering the SRS inoperative, which could lead to personal injury or death in the event of a severe frontal
or side collision, all SRS service work must be performed by an authorized Acura dealer.
Improper service procedures, including incorrect removal and installation of the SRS could lead to personal injury
caused by unintentional deployment of the airbags and/or side airbags.
Do not bump or impact the SRS unit, front impact sensors, side impact sensors whenever the ignition switch is
ON (II), or for at least 3 minutes after the ignition switch is turned OFF. Otherwise, the system may fail in a collision,
or the airbags may deploy.
SRS electrical connectors are identified by yellow color coding. Related components are located in the steering
column, front console, dashboard, dashboard lower panel, in the dashboard above the glove box, in the front seats,
and around the floor. Do not use electrical test equipment on these circuits.

NOTE: If you are going to remove heavy components
such as suspension or the fuel tank from the rear of the
vehicle, first support the front of the vehicle with tall
safety stands. When substantial weight is removed
from the rear of the vehicle, the center of gravity can
change and cause the vehicle to tip forward on the hoist.
1. Position the hoist lift blocks (A), on safety stands,
under the vehicle’s front support points (B) and rear
support points (C).
2. Raise the hoist a few inches, and rock the vehicle
gently to be sure it is firmly supported.
3. Raise the hoist to full height, and inspect the lift
points for solid contact with the lift blocks.
To support the vehicle on safety stands, use the same
support points (B and C) as for a frame hoist. Always
use safety stands when working on or under any
vehicle that is supported only by a jack.
1. Set the parking brake.
2. Block the wheels that are not being lifted.
3. When lifting the rear of the vehicle, put the shift
lever in reverse, or the automatic transmission in
the P position.
4. Position the floor jack under the front jacking
bracket (A) or rear jacking bracket (B), center the
jacking bracket in the jack lift platform (C), and jack
up the vehicle high enough to fit the safety stands
under it.
5. Position the safety stands under the support points
and adjust them so the vehicle is level.
6. Lower the vehicle onto the stands.

Towing
B
A
B
If the vehicle needs to be towed, call a professional
towing service. Never tow the vehicle behind another
vehicle with just a rope or chain. It is very dangerous.
There are three popular methods of towing a vehicle.
The operator loads the vehicle
on the back of a truck. This is the best way of
transporting the vehicle.
To accommodate flat-bed equipment, the vehicle is
equipped with towing hooks (A) and tie down hooks (B).
The towing hook can be used with a winch to pull the
vehicle onto the truck, and the tie down hook slots can
be used to secure the vehicle to the truck.
The tow truck uses two
pivoting arms that go under the tires (front or rear) and
lifts them off the ground. The other two wheels remain
on the ground. This is an acceptable way of towing the
vehicle.
The tow truck uses metal
cables with hooks on the ends. These hooks go around
parts of the frame or suspension and the cables lift that
end of the vehicle off the ground. The vehicle’s
suspension and body can be seriously damaged if this
method of towing is attempted.
If the vehicle cannot be transported by flat-bed, it
should be towed with the front wheels off the ground. If
due to damage, the vehicle must be towed with the
front wheels on the ground, do the following:
Release the parking brake.
Shift the transmission to Neutral.
Release the parking brake.
Start the engine.
Shift to the D position, then to the N position.
Turn off the engine.
It is best to tow the vehicle no farther than 50 miles
(80 km), and keep the speed below 35 mph (55 km/h).
Improper towing preparation will damage the
transmission. Follow the above procedure exactly. If
you cannot shift the transmission or start the engine
(automatic transmission), the vehicle must be
transported on a flat-bed.
Trying to lift or tow the vehicle by the bumpers will
cause serious damage. The bumpers are not
designed to support the vehicle’s weight.

General Information
Parts Marking
To deter vehicle theft, certain major components are marked with the vehicle identification number (VIN). Original
parts have self-adhesive labels. Replacement body parts have generic self-adhesive labels. These labels should not be
removed. The original engine or transmission VIN plates are not transferable to the replacement engine or
transmission.
NOTE: Be careful not to damage the parts marking labels during body repair. Mask the labels before repairing the part.

API CERTIFICATION SEAL Recommended Engine Oil
For RSX and Premium models For Type S model
For details of lubrication points and type of lubricants to be applied, refer to the illustrated index and various work procedures (such as
Assembly/Reassembly, Replacement, Overhaul, Installation, etc.) contained in each section.
A Engine ACURA Motor Oil: Except Type S models-P/N 08798-9023A (5W-20)
Honda Motor Oil: Type S model-P/N 08798-9014 (5W-30)
Look for the API certification seal on the oil container as shown below. Make sure
it says ‘‘For Gasoline Engines’’. SAE viscosity: See chart below.
B Manual transmission ACURA Manual Transmission Fluid (MTF): P/N 08798-9016A
Always use Acura MTF. Using motor oil can cause stiffer shifting because it does
not contain the proper additives.
Automatic transmission ACURA Automatic Transmission Fluid (ATF-Z1): P/N 08200-9001
Always use Acura ATF-Z1. Using a non-Acura ATF can affect shift quality.
C Brake system (including ABS line) ACURA DOT 3 Brake Fluid: P/N 08798-9008A
Always use Acura DOT 3 Brake Fluid. Using a non-Acura brake fluid can cause
corrosion and decrease the life of the system.
D Clutch line ACURA DOT 3 Brake Fluid: P/N 08798-9008A
Always use Acura DOT 3 Brake Fluid. Using a non-Acura brake fluid can cause
corrosion and decrease the life of the system.

NOTE:
Air temperature must be between 59 and 100 ° F (15
and 38 ° C) during this procedure.
On 2002-2004 models: After this inspection, or any
subsequent repair, reset the engine control module
(ECM)/powertrain control module (PCM) to clear any
diagnostic trouble codes (DTCs) (see page 11-4).
On 2005-2006 models: After this inspection, you must
select ECM/PCM reset using the Honda Diagnostic
System (HDS) (see page 11-4), otherwise the ECM/
PCM continues to stop the fuel injectors.
The battery must be in good condition and fully
charged.
If you disconnect the battery, do the ECM/PCM idle
learn procedure.
– 2002-2004 models (see page 11-349)
– 2005-2006 models (see page 11-349)
Use a starter system tester.
Connect and operate the equipment in accordance
with the manufacturer’s instructions.
1. Hook up the following equipment:
Ammeter, 0 400 A
Voltmeter, 0 20 V (accurate within 0.1 V)
Tachometer, 0 1,200 rpm
2. 2002-2004 models: Remove the No. 17 (15 A) fuse
from the under-dash fuse/relay box.
2005-2006 models: Connect the HDS to the data link
connector (DLC) (see step 2 on page 11-3). Turn the
ignition switch ON (II), then select PGM-FI,
INSPECTION, and then All INJECTORS OFF on the
HDS.
3. With the shift lever in N or P (A/T) or the clutch
pedal pressed (M/T), turn the ignition switch to
START (III).
The starting system is OK. Go to step 9.
Go to step 4.
4. Check the battery condition. Check electrical
connections at the battery, the negative battery
cable to body, the engine ground cables and the
starter for looseness and corrosion. Then try
cranking the engine again.
Repairing the loose connection corrected the

1. Connect the Honda Diagnostic System (HDS) to the
data link connector (DLC) (see step 2 on page 11-3),
and check for DTCs. If a DTC is present, diagnose
and repair the cause before inspecting the ignition
timing.
2. Start the engine. Hold the engine speed at 3,000
rpm without load (in Park or Neutral) until the
radiator fan comes on, then let it idle.
3. Check the idle speed (see page 11-348).
4. Select ‘‘SCS’’ mode using the HDS.
5. Connect the timing light to the service loop.
6. Aim the light toward the pointers (A) on the cam
chain case. Check the ignition timing under a no
load condition (headlights, blower fan, rear window
defogger, and air conditioner are turned off).
7. If the ignition timing differs from the specification,
check the cam timing. If the cam timing is OK,
update the engine control module (ECM)/
powertrain control module (PCM) if it does not
have the latest software (see page 11-6), or
substitute a known-good ECM/PCM (see page 11-7),
then recheck. If the system works properly, and the
ECM/PCM was substituted, replace the original
ECM/PCM (see page 11-284).

1. Inspect the electrodes and ceramic insulator.
Burned or worn electrodes may be caused by:
– Advanced ignition timing
– Loose spark plug
– Plug heat range too hot
– Insufficient cooling
Fouled plug may be caused by:
– Retarded ignition timing
– Oil in combustion chamber
– Incorrect spark plug gap
– Plug heat range too cold
– Excessive idling/low speed running
– Clogged air cleaner element
– Deteriorated ignition coils
2. If the spark plug electrode is dirty or contaminated,
clean the electrode with a plug cleaner.
NOTE:
Do not use a wire brush or scrape the iridium
electrode since this will damage the electrode.
Use a chemical cleaner such as Carb Spray to
clean contamination on the electrode.
When using a sand blaster spark plug cleaner, do
not clean for more than 20 seconds to avoid
damaging the electrode.
3. Do not adjust the gap of iridium tip plugs (A);
replace the spark plug if the gap is out of
specification.
4. Replace the plug at the specified interval, or if the
center electrode is rounded (A). Use only the spark
plugs listed.
5. Apply a small amount of anti-seize compound to
the plug threads, and screw the plugs into the
cylinder head, finger-tight. Then torque them.
