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 brake fluid is felt coming from return tube, a solenoid is leaking. Proceed to step 5). If brake fluid is not felt coming from return tube, 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" and "6" positions. Repeat this procedure at least 3-4 times. Start engine, and release parking brake.
- Place ABS tester mode selector to "1" position. Push START TEST button. With pump motor running, place finger over top of solenoid return tube inside modulator reservoir.
- If solenoid leakage has stopped, install modulator reservoir filter, and refill reservoir to MAX level. If any solenoid is still leaking, replace modulator.
