check engine ACURA RL KA9 1996 Service Owner's Manual

The numbers in the middle of the API Service label tell

you the oil's SAE viscosity or weight. Select the oil for

your vehicle according to this chart:

Ambient Temperature

An oil with a viscosity of 5W - 30 is preferred for

improved fuel economy and year-round protection in

the vehicle. You may use a 10W - 30 oil if the climate in

your area is limited to the temperature range shown on

the chart.

4. Run the engine for more than 3 minutes, then check

for oil leakage.ProCarManuals.com

Oil Pan

Installation

Install the oil pan in the reverse order of removal:

• Always use new O-rings.

• Oil pan and cylinder block mating surface must be

clean.

1. Apply liquid gasket to the cylinder block, then install

the oil
pan.

NOTE:

• Use liquid gasket, Part No. 08718 - 0001 or 08718

0003.

• Check that the mating surfaces are clean and dry

before applying liquid gasket.

• Apply liquid gasket evenly, being careful to cover

all the mating surface.

• Do not apply liquid gasket to O-ring grooves.

• To prevent oil leakage, apply liquid gasket to the

inner threads of the bolt holes.

• Do not install the parts if 5 minutes or more have

elapsed since applying liquid gasket.

Instead, reapply liquid gasket after removing old

residue.

•
After assembly,
wait
at
least
30
minutes before
fill-

ing the engine with oil.

NOTE: Use new O-rings. Apply oil to the O-rings

before installation.

Cap Testing
Testing

1. Remove the radiator cap, wet its seal with engine

coolant, then install it on the pressure tester.

RADIATOR

CAP

2. Apply a pressure of 93- 123 kPa (0.95- 1.25 kgf/cm2,

14-18 psi).

3. Check for a drop in pressure.

4. If the pressure drops, replace the cap.
1. Wait until the engine is cool, then carefully remove

the radiator cap and fill the radiator with engine

coolant to the top of the filler neck.

2. Attach the pressure tester to the radiator and apply

a pressure of 93-123 kPa (0.95 - 1.25 kgf/cm2, 14 -

18
psi).

6. After completing your tests, reinstall both PCM's, and destroy the temporary key.

If the inspection for a particular code requires voltage or resistance checks at the PCM connectors, remove the right

door sill molding. Pull the carpet back to expose the PCM. Unbolt the PCM cover, and connect the backprobe sets and

a digital multimeter as described below. Check the system according to the procedure described for the appropriate code(s)

listed on the following pages.

IV. Known-Good PCM Substitution

Use the following procedure if you need a known-good PCM to test a vehicle. It allows you to swap an PCM from a

"donor" vehicle without having to program it to the test vehicle's ignition key.

1. Cut a temporary ignition key for the test vehicle with a non-immobilizer key blank.

2. Remove the PCM from the test vehicle.

3. Write the test vehicle's VIN on the PCM you just removed to avoid confusing it with the donor vehicle's PCM.

4. Remove the known-good PCM from the donor vehicle, and install it in the test vehicle.

5. Tape the donor vehicle's ignition key head-to-head to the test vehicle's temporary key. The PCM will recognize the code

from the donor vehicle's key and allow you to start the engine with the temporary key.ProCarManuals.com

How to Set Readiness Codes

Catalytic Converter

NOTE:

• Do not turn the ignition switch OFF.

• When the battery negative cable is disconnected, all

readiness codes are cleared.

Required condition ('96 - 97 models):

• Ambient temperature between 32 - 95°F (0 - 35°C).

• Altitude below 2,400 m (7,874 ft.).

Required condition ('98 - 01 models):

Ambient temperature between 20 - 95°F (-7 - 35°C).

1. Connect the scan tool to the Data Link Connector

(DLC).

2. Start the engine. Hold it at 3,000 rpm with no load

(in Park or neutral) until the radiator fan comes on.

3. Drive for about 10 minutes without stopping on a

highway or freeway. Your speed can vary.

4. '96 - 97 models:

With the transmission in D4 position, drive at a

steady speed between 33 - 37 mph (53 - 59 km/h)

for 30 seconds.

'98 - 01 models:

With the A/T in D4 position, drive at a steady speed

between 50 - 62 mph (80 - 100 km/h) for 30 sec-

onds.

5. Do step 4 three times. Between each repetition,

close the throttle completely for 1 - 2 seconds. If the

engine is stopped during this part of the procedure,

go to step 3 and do the procedure again.

6. Check for the readiness code with the scan tool.

EGR Monitor

NOTE:

• Do not turn the ignition switch OFF.

• When the battery negative cable is disconnected, all

readiness codes are cleared.

Required condition ('96 - 97 models):

1 again.

1. Make sure the gasoline level is 60 - 90% of fuel tank

capacity (not full).

2. Turn the ignition switch OFF.

3. Let the vehicle sit more than 8 hours.

4. '96 - 97 models:

Make sure the outside temperature is 32 - 95°F (0 -

35°C).

'98 - 01 models:

Make sure the outside temperature is 20 - 95°F (-7 -

35°C).

5. Connect the scan tool to the Data Link Connector

(DLC).

6. Start the engine and drive for about 15 minutes.

7. '96 - 97 models:

Keep the vehicle at a steady speed between 50 - 62

mph (80 - 100 km/h), without moving the accelera-

tor pedal, for about 1 minute.

'98 - 01 models:

Keep the vehicle at a steady speed between 50 - 70

10. Check for the readiness code with the scan tool. If

the readiness code does not set, go to step 11.

11. When ambient temperature is less than 32°F (0°C),

hold the engine at 3,000 rpm with no load (in Park

or neutral) until the radiator fan comes on.

12. When ambient temperature is more than 86°F

(30°C), remove the fuel fill cap, then install the fuel

fill cap.

13. After step 12, drive for about 20 minutes on a free-

way.

14. '96 - 97 models:

Keep the vehicle at a steady speed between 50 - 62

mph (80 - 100 km/h), without moving the accelera-

tor pedal, for about 1 minute.

'98 - 01 models:

Keep the vehicle at a steady speed between 50 - 70

mph (80 - 114 km/h), without moving the accelera-

tor pedal, for about 1 minute.

15. Stop the vehicle (do not stop the engine).

16. Repeat steps 14 and 15 two more times.
