Hydraulic Control Assembly - Antilock Brakes: Service and Repair
System Bleed
If the brake fluid is completely drained from the ABS reservoir (air enters the modulator unit) at any time, bleed the air from the modulator unit as
follows.
NOTE: This procedure is for bleeding the modulator unit only. It is recommended the complete system be bled whenever any hydraulic connection is
opened. See: Brake Bleeding/Service and Repair
USING HONDA PGM TESTER
The ABS can be bled using the Honda PGM Tester and the ABS Diagnostic Kit to run the ABS pump. Connect the tester and module A (refer to
PGM users guide), then follow the tester's prompts.
MANUAL BLEEDING
1. Fill the reservoir to the MAX (upper) level with fresh brake fluid.
2. Connect the rubber tube to the bleeder on the modulator unit and set the other end of the rubber tube in a container.
3. Loosen the bleeder, and start the engine to activate the pump motor.
NOTE: Take care not to spill the brake fluid from the container.
4. Tighten the bleeder when clean fluid starts to flow out, or if fluid level in the reservoir falls below the minimum level marked on the side.
NOTE: Take care not to deplete the brake fluid in the reservoir. Refill as necessary.
5. Stop the engine after the pump motor stops
NOTE: If the ABS indicator light comes on and the pump motor stops, restart the engine and repeat steps 3 through 5 above.
Flushing
CAUTION: Do not loosen the relief plug on the accumulator.
NOTE: Brake fluid replacement procedure explained in this article is for the brake fluid in the modulator unit (that is, the brake fluid in the
high-pressure passage and in the reservoir). Fluid replacement procedures for the rest of the brake system are incorporated into the brake bleeding
procedures for the basic brake hydraulic system. See: Brake Bleeding/Service and Repair
1. Start the engine and let it idle for a minute. Stop the engine.
2. Check the brake fluid level in the reservoir. It should be below the MAX (upper) level line.
3. Use the steps below to drain the rest of the brake fluid from the modulator unit.
NOTE: Approximately 35 - 45 ml (1 1/6 - 1 1/2 fl.oz) of the fluid is drained at each try.
Modulator Unit Location
A) Attach a wrench to the maintenance bleeder.
