The vehicle (where a record says)

A record is under an engine, a drive or a series only where it says so: the characters of the vehicle identification number filed with a complaint, its text, or what its document says it applies to. A record that does not say is kept as "not stated". The filed numbers and the documents do not tell 4WD from AWD.

Record by record

4 records state a cause or a remedy. Each record is shown as short labels in the order fault → finding the cause → correction. Press a label to narrow to the records that state it.

Symptom

Component named as the cause

A ribbon is as wide as the records that state both of its ends (only the commonest are drawn). A record that names several symptoms or components runs through each. Orange is records that say the fault came back or was not fixed. Results come from owners’ reports only; one that does not say is “result not stated”. None of this is a likelihood of a cause or a rate at which work succeeds.

      What the documents say to do

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

      Confirm

      • Perform the "Power Steering System Test" found in SI and make any necessary repairs based on system diagnosis.

      Repair

      1. Dealers replace the hydro-boost relief valve.
      2. Dealers test the hydro-boost assembly for functional operation and replace it if it fails.

      Caution

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

    Cause
    On certain vehicles, the hydraulic brake booster's pressure accumulator may crack and/or separate from the Hydro-Boost assembly during normal vehicle operating conditions. If a separation occurred and the hood of the vehicle was open, fragments from the accumulator could cause injury to people in the immediate area. In addition, the presence of this crack or fractured surface could allow the hydraulic fluid to leak from the accumulator circuit of the booster assembly. The loss of fluid would cause increased steering and braking effort. Correction: Dealers will test and, if necessary, replace the Hydro-Boost assembly.
