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. Code 95 will set first and turn on ANTI-LOCK warning light. When brake pedal is pressed, Code 96 will set.
  4. Brake switch is normally held open by brake pedal. Pressing brake allows switch to close.
