Alb Controller: Adjustments: Adjustment

WARNING: This page is about a different car, the 2006 Dodge Sprinter. However, it is still accessible from the selected car via links, so may be relevant.
  1. Clean any debris away from the test ports caps at the ALB controller.
  2. Connect brake adapters special tool 9297 to the test ports at the ALB controller.
  3. Install a Pressure Gauge, Special Tool C-4007-A, to the adapters.
  4. Tighten all tube nut fittings to 17 N.m (145 in. lbs.) torque.
  5. Bleed any air out of the system. This includes bleeding the air from the hose between the pressure test fitting and pressure gauge, which is done at the pressure gauge.
    NOTE: Adjustment is determined for the automatic load-dependent brake power control system according to the ALB plate. This is housed in the stowage compartment under the front passenger's door panel. The part number of the rear spring is stamped into the spring eye. This must correspond to the part number of the rear spring on the ALB plate.
  6. To accurately adjust the rear axle load you must first determine the rear axle load by weighing the vehicle at a local scale.
  7. Install the brake pedal winch Special tool 9296 between the brake pedal and the driver seat and slowly turn the dial until the specified inlet brake pressure is indicated at the gauge.
    NOTE: The pressure gauge, connected at the ALB controller must indicate the outlet pressure which is assigned on the ALB plate to the rear axle load determined.
    NOTE: If the rear axle load determined is between two figures indicated on the ALB plate, the outlet pressure should be determined accordingly.
  8. If the pressure measured differs from the specification, adjust the ALB controller. See Fig 1.
  9. Loosen the brake pedal winch.
  10. Adjust the outlet pressure by turning the adjusting nut. See Fig 1. To increase pressure - tighten the adjusting nut. To reduce pressure - loosen the adjusting nut. 
  11. After adjustment reinstall the brake pedal winch and recheck the pressures and readjust if needed.
  12. Tighten the lock adjusting nut.
