Reassembly

Never use an air hose or dry brush to clean brake assemblies.

Use an OSHA-approved vacuum cleaner to avoid breathing brake dust.

Contaminated brake discs or pads reduce stopping ability.

When reusing the pads, always reinstall the brake pads in their original positions to prevent loss of braking efficiency.

CAUTION:

Do not spill brake fluid on the vehicle; it may damage the paint; if brake fluid does contact the paint, wash it off imme-

diately with water.

Clean all parts in brake fluid and air dry; blow out all passages with compressed air.

Before reassembling, check that all parts are free of dust and other foreign particles.

Replace parts with new ones whenever specified to do so.

Make sure no dirt or other foreign matter is allowed to contaminate the brake fluid.

Always use Genuine Honda DOT 3 Brake Fluid. Using a non-Honda brake fluid can cause corrosion and decrease the

life of the system.

NOTE:

Coat piston, piston seal, and caliper bore with clean brake fluid.

Replace all rubber parts with new ones whenever disassembled.

: Use recommended rubber grease in the caliper seal set.

: Use recommended seal grease in the caliper seal set.

Diagnostic Trouble Code (DTC)

DTC Erasure (MES Mode)

NOTE: This operation can also be done with the Honda PGM Tester.

1. Connect the SCS service connector to the service check connector (2P) under the glove box.

2. Depress the brake pedal.

3. Turn the ignition switch ON (II) while keeping the brake pedal depressed.

4. After the ABS indicator light goes off, release the brake pedal.

5. After the indicator light comes on, depress the brake pedal again.

6. After the indicator light goes off, release the brake pedal again.

7. After few seconds, the indicator light blinks twice and the DTC is erased. If the indicator light does not blink twice,

repeat steps 1 through 6. If the indicator light stays ON after the indicator light blinks twice, check the DTC because a

problem was detected during initial diagnosis before shifting to MES mode.

8. Turn the ignition switch OFF, and remove the SCS service connector.

Conditions for DTC erasure

Vehicle speed is at 6 mph (10 km/h) or less.

The SCS service connector is connected before the ignition switch is turned ON (II).

The brake pedal is depressed before the ignition switch is turned ON (II).ProCarManuals.com

Five-step Troubleshooting

1. Verify The Complaint

Turn on all the components in the problem circuit to

verify the customer complaint. Note the symptoms.

Do not begin disassembly or testing until you have

narrowed down the problem area.

2. Analyze The Schematic

Look up the schematic for the problem circuit.

Determine how the circuit is supposed to work by

tracing the current paths from the power feed

through the circuit components to ground. If several

circuits fail at the same time, the fuse or ground is a

likely cause.

Based on the symptoms and your understanding of

the circuit operation, identify one or more possible

causes of the problem.

3. Isolate The Problem By Testing The Circuit

Make circuit tests to check the diagnosis you made

in step 2. Keep in mind that a logical, simple proce-

dure is the key to efficient troubleshooting. Test for

the most likely cause of failure first. Try to make

tests at points that are easily accessible.

4. Fix The Problem

Once the specific problem is identified, make the

repair. Be sure to use proper tools and safe proce-

dures.

5. Make Sure The Circuit Works

Turn on all components in the repaired circuit in all

modes to make sure you've fixed the entire prob-

lem. If the problem was a blown fuse, be sure to

test all of the circuits on the fuse. Make sure no new

problems turn up and the original problem does not

recur.
Wire Color Codes

The following abbreviations are used to identify wire

colors in the circuit schematics:

WHT .............................White

YEL ............................... Yellow

BLK .............................. Black

BLU
..............................
Blue

GRN ............................. Green

RED
..............................
Red

ORN ............................. Orange

PNK.............................. Pink

BRN .............................. Brown

GRY.............................. Gray

PUR .............................. Purple

LT BLU ......................... Light Blue

LT GRN ........................ Light Green

The wire insulation has one color or one color with

another color stripe. The second color is the stripe.

WHT/BLK

NOTE: Different wires with the same color in the same

system have been given number suffixes to distinguish

them (for example, YEL1 and YEL2 are not the same).ProCarManuals.com
