Blank Message Screen

  1. Connect DRB-II to a different vehicle. If message screen is still blank, DRB-II or cable adapter are faulty. Substitute to find faulty component.
  2. If message screen is not blank, DRB-II and cable adapter are functioning properly. Inspect diagnostic connector for proper wire placement, damaged terminals and pushed-out pins. Repair as necessary.
  3. If engine diagnostic connector is okay, check for continuity between Black/tracer wire (tracer color may vary) and ground at engine diagnostic connector using an ohmmeter. If continuity does not exist, repair open in Black/tracer wire.
