Modulator Solenoid Leak Test
- Park vehicle on level surface. Block wheels, and place automatic transmission in Park or manual transmission in Neutral. Turn ignition off. Connect ABS Tester (07HAJ-SG0010A or 07HAJ-SG0010B) to Orange 6-pin test connector, located under passenger's seat.
- Remove modulator reservoir filter, and fill reservoir to MAX level. DO NOT use aerated brake fluid bled from power unit. Use ABS "T" Wrench (07HAA-SG00101) to relieve accumulator line pressure. See Figure
.
- Start engine, and release parking brake. Place ABS tester mode selector to "1" position. Push START TEST button. See Figure
. With pump motor running, place finger over top of solenoid return tube inside modulator reservoir. See Fig 1
. If equipped with separator in reservoir, place finger over separator.

- If brake fluid is felt coming from return tube or passing through separator, a solenoid is leaking. Proceed to next step. If brake fluid is not felt coming from return tube or through separator, solenoids are okay. Install modulator reservoir filter, and refill reservoir to MAX level.
- Relieve accumulator line pressure again. Place ABS tester mode selector to "3", "4" and "5" positions. Repeat pressure relief procedure at least 3-4 times at each position. Repeat steps 3) and 4).
- If solenoid leakage has stopped, install modulator reservoir filter, and refill reservoir to MAX level. If any solenoid is still leaking, replace modulator.
