Solenoid Leak Test

NOTE: If solenoid leaks excessively, brake fluid in modulator reservoir will rise when ABS power unit is operated.
  1. Turn ignition off. Connect ABS Tester (07HAJ-SG0010B) to 6-pin inspection connector. See Figure for connector location. Ensure vehicle is on level ground and automatic transmission is in Park or manual transmission is in Neutral.
  2. Remove modulator reservoir filter. Fill modulator reservoir to MAX level. Bleed high pressure fluid from maintenance bleeder screw. See RELIEVING ACCUMULATOR/LINE PRESSURE  under BLEEDING BRAKE SYSTEM. Start engine, and release parking brake. Place mode selector to "1" position. Push START TEST button.
  3. While ABS pump is running, place finger over top of solenoid return tube located inside of modulator reservoir. If brake fluid is felt coming from return line, solenoid is leaking. Relieve accumulator pressure. See RELIEVING ACCUMULATOR/LINE PRESSURE  under BLEEDING BRAKE SYSTEM.
  4. Place mode selector of ABS tester in position "3" and "6". Run test 3-4 times. Place mode selector of ABS tester to "1" position. Start engine, and release parking brake. Push START TEST button on ABS tester.
  5. While ABS pump is running, place finger over top of solenoid return tube located inside of modulator reservoir. If solenoid leakage has stopped, refill modulator reservoir to MAX level. No further testing is required. If solenoid is still leaking, replace solenoid. See SOLENOID  under REMOVAL & INSTALLATION.
