Diagnostic Aids

WARNING: When replacing motor pack, DO NOT place hands near motor pack modulator gears. Gears may have enough preload tension to cause personal injury.
  1. Connect "Scan" tester. Perform ABS motor tension release special test before removing motor pack.
  2. ABS will initialize when vehicle is driven at least 3 MPH (5 km/h).
    NOTE: System initialization alternates between left front/rear and right front/rear with each ignition cycle.
  3. When diagnosing intermittent problems, select MALF HISTORY from "Scan" tester ABS menu. Supplemental data can be used to duplicate problem.
