- This condition occurs in 2WD, on either 2WD or 4WD vehicles. Problem happens when making normal or hard stops, and rear brakes may lock-up. If problem occurred with 2WD or 4WD vehicle (while in 2WD), go to step 2). If problem occurred with 4WD vehicle (while in 4WD), go to step 3).
- Disconnect control module connector to disable system. Drive vehicle in 2WD mode and make several normal stops to check rear brake operation. If rear brake operates properly, replace electro-hydraulic valve, and retest system. If rear brakes grab or lock-up easily, repair rear brake system (mechanical), and retest system.
- Unplug control module connector. Turn ignition on. Shift transfer case into 4WD mode. Measure voltage between pin No. 5 and chassis ground. See Figure . If voltage is less than one volt, replace electro-hydraulic valve. If voltage is one volt or more, repair or replace 4WD indicator switch, located on transfer case.
