Pinpoint Test J: Excessive Dump Solenoid Activity (DTC 5) (Part 3 Of 3):

DESCRIPTION

Code 5 is generated when the maximum number of allowable dump pulses has been exceeded. The system will only recognize this condition during an anti-lock stop in 2WD mode. The code can be caused by a blocked RABS dump valve orifice, a stuck dump valve, an open circuit in Circuit 210 (LB), a worn or damaged 4x4 transfer case that causes the vehicle to remain in 4x4 after 4x2 has been selected, or mechanical problems in the rear brake system (rear brakes might lock).

POSSIBLE CONTRIBUTING BASE BRAKE COMPONENT/VEHICLE WIRING CONCERNS

- Parking brake drag.
- Worn or damaged 4x4 switch.
- Rear brake assembly grabby or hanging up.
- Connector corrosion or contamination.
- Intermittent open in Circuit 210 (LB).
- Pierced wire insulation to battery power (4x4 only).
