Parking Brake Switch

NOTE: For testing of body control ECU side of parking brake switch circuit, see appropriate BODY CONTROL SYSTEMS article.
  1. Check for continuity between parking brake switch body and switch mounting. If continuity is not present, clean mounting area between switch and mounting (poor ground). If continuity is present, go to next step.
  2. Disconnect electrical connector from switch. Check for continuity between ground and switch terminal. With switch pin released, continuity should be present. Ensure continuity is not present with switch pin pushed in. If continuity is not as specified, replace parking brake switch.
