Diagnostic Aids

  1. Suspected intermittents or opens at connectors can be detected with diagnostic service probe which permits voltage to be measured on wires without unplugging connectors. Ensure all terminals make good connection.
  2. When diagnosing intermittent problems, select MALF HISTORY from Tech 1 scan tester ABS menu. Supplemental data can be used to duplicate problem.
  3. Brake switch is normally open. Depressing brake pedal closes switch and completes circuit. Check switch adjustment.
