Modulator Unit Bleeding (ABS)

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. 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.
