    Hydro-boost brake assist and power steering share one hydraulic supply (four campaigns)

    Why it happens：Some vehicles were built with an out-of-specification hydro-boost housing relief valve bore.

    • If left：The valve O-ring seal may fracture, and steering effort may be slightly higher while braking or parking.
    • If left：The loss of fluid would increase steering and braking effort, and a crash may occur without prior warning.
    • If left：A hydraulic pump driveshaft can fracture, causing immediate loss of power steering assist.
    • If left：On hydro-boost vehicles the same failure removes brake power assist once the reserve pressure is used up.
    • If left：Power steering assist would be lost and steering effort would rise.
    • If left：On hydro-boost vehicles the hose failure could also remove power brake assist.
    • If left：Power steering fluid sprayed onto hot engine parts could cause an engine compartment fire.
    • If left：The Hydro-Boost unit includes a pneumatic accumulator that serves as a reserve and provides a transition between power assisted and manual braking when pressure supply is lost. The number of accumulator-assisted stops varies with previous steering and braking inputs.
    • If left：Loss of boost with a depleted reserve sharply increases brake pedal effort: a driver used to applying 20 lbs for a moderate 0.3 g deceleration may have to apply 130 lbs or more.
    • If left：In the steering test, the test vehicle required 45 in-lb (= 5.08 N·m) with the system intact and 300 in-lb (= 33.9 N·m) with the system failed.

    Caution：An inoperative pump raises steering and braking effort but does not completely remove the ability to steer or slow the vehicle.

    Passlock theft deterrent: starts then stalls / no-start with security lamp

    Why it happens：A magnet in the ignition cylinder produces a unique voltage across a Hall effect sensor in the ignition housing; the BCM and lock cylinder enable starting.

    Caution：Loss of Ignition 1 voltage to the BCM gives the same start-then-stall behaviour.

7 records that touch this generation only at its boundary (model year 2000); not counted for this vehicle

In model year 2000 the previous generation was also sold under the same name. These records state no other model year of this generation, and either state years outside it or call the vehicle the old style: they do not say which generation they mean, so they are not counted among the causes or under the cards. The ground for the shared year:

01-03-08-001; Revised Fastener Tightening Specifications; 2000 Chevrolet and GMC C/K Pickup and Utility Models (Classic), 2000 Cadillac Escalade
