System Pre Check

Connector Diagram:

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 may 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 brake drums may lock.)

POSSIBLE CONTRIBUTING BASE BRAKE COMPONENT/VEHICLE WIRING CONCERNS
- Parking brake drag
- Worn or damaged 4x4 switch
- Rear brake assembly grabbing or hanging up
- Connector corrosion or contamination
- Intermittent open circuit in Circuit 210 (LB)
- Pierced wire insulation to battery power (4x4 only)
