Engine Coolant Refilling and Bleeding

CAUTION: When pouring engine coolant, be sure to

shut the relay box lid and not let coolant spill on the

electrical parts or the paint. If any coolant spills, rinse it

off immediately.

NOTE:

• Perform this maintenance when the engine is cool.

• Before replacing the coolant, turn the ignition ON,

slowly turn the climate control temperature knob to

90° and turn off the ignition. This will allow the

coolant in the heater to drain out with the rest of the

system.
1. Open the hood, the rear window and the engine

cover.

2. Remove the cover protecting the water pipes and

shift cables on the underside of the car.

3. Before removing the expansion tank cap, first

loosen the cap to lower pressure.

CAUTION: Do not remove the expansion tank cap

when engine is hot. The coolant is under pressure

and may blow out and scald you. Open the cap

slowly when the engine is cool.

4. Loosen the drain plug in the bottom of the radiator,

and drain the coolant.

5. Remove the two drain bolts from the water pipes,

and drain the coolant.

HID Lamp System Troubleshooting

1. Check the No. 49 (20 A) or No. 52 (20 A) fuse in the

main under-hood fuse/relay box.

Are the fuses OK?

YES — Go to step 2.

NO — Replace the fuse (s), and recheck.

2. Substitute a known-good HID bulb and recheck.

Does the headlight low beam come on?

YES — Replace the HID bulb.

NO — Go to step 3.

3. Disconnect the 2P connector from the inverter unit.

4. Turn the combination light switch ON.

5. Measure the voltage between the No. 2 terminal of

the inverter unit 2P connector and body ground.
7. Check for continuity between the No. 1 terminal of

the inverter unit 2P connector and body ground.

Is there continuity?

YES — Substitute a known-good inverter, and

recheck. If the symptom/indication goes away,

replace the original inverter unit.

NO — Repair open in the wire between the inverter

unit and body ground. If the wire is OK, check for

poor ground at G202 or G302.ProCarManuals.com

Transmitter Test

NOTE:

• If the doors unlock or lock with the transmitter, but

the LED on the transmitter does not come on, the

LED is faulty; replace the transmitter.

• If any door is open, you cannot lock the door with the

transmitter.

• If you unlocked the doors with the transmitter, but do

not open any of the doors within 30 seconds, the

doors relock automatically.

• The doors do not lock or unlock with the transmitter

if the ignition key is inserted in the ignition switch.

1. Press the lock or unlock button five or six times to

reset the transmitter.

• If the locks work, the transmitter is OK.

• If the locks don't work, go to step 2.

2. Open the transmitter and recheck for water damage.

• If you find any water damage, replace the transmit-

ter.

• If there is no water damage, go to step 3.

3. Replace the transmitter battery with a new one, and

try to lock and unlock the doors with the transmitter

by pressing the lock or unlock button five or six

times.

• If the doors lock and unlock, the transmitter is OK.

• If the doors don't lock and unlock, go to step 4.

4. Reprogram and register the transmitter, then try to

lock and unlock the doors.

• If the doors lock and unlock, the transmitter is OK.

• If the doors don't lock and unlock, replace the trans-

mitter
Transmitter Programming

Storing transmitter codes:

The codes of up to three transmitters can be stored into

the keyless receiver unit memory. (If a fourth code is

stored, the code which was input first will be erased.)

NOTE: It is important to maintain the time limits

between the steps. Make sure the doors, hood and tail-

gate are closed.

1. Turn the ignition switch ON (II).

2. Within 1 to 4 sec., push the transmitter lock or

unlock button with the transmitter aimed at the key-

less receiver unit by the steering column.

3. Within 1 to 4 sec., turn the ignition switch OFF.

4. Within 1 to 4 sec., turn the ignition switch ON (II).

5. Within 1 to 4 sec., push the transmitter lock or

unlock button with the transmitter aimed at the key-

less receiver unit by the steering column.

6. Within 1 to 4 sec., turn the ignition switch OFF.

7. Within 4 sec., turn the ignition switch ON (II).

8. Within 1 to 4 sec., push the transmitter lock or

unlock button with the transmitter aimed at the key-

less receiver unit by the steering column.

9. Within 1 to 4 sec., turn the ignition switch OFF.

10. Within 4 sec., turn the ignition switch ON (II).

11. Within 1 to 4 sec., push the transmitter lock or

unlock button with the transmitter aimed at the key-

less receiver unit by the steering column.

For the details of lubrication points and types of lubricants to be appl\
ied, refer to the illustrated index and various work
procedures (such as Assembly/Reassembly, Replacement, Overhaul, Install\
ation, etc.) contained in each section.
*1: Always use Honda Manual Transmission Fluid (MTF). Using motor oil can \
cause stiffer shifting because it does not contain theproper additives.
*2: Always use Honda ATF-Z1 (ATF). Using a non-Honda ATF can affect shift \
quality.
*3: Always use Honda Heavy Duty DOT3 Brake Fluid. Using a non-Honda brake fl\
uid can cause corrosion and decrease the life of the system.
