Normally, when the brake pedal is applied, an electrical signal from the stoplamp circuit to the pcm deactivates the system. Insert a test lead into the brake pedal position switch signal pin of the oem harness connector. After scanning them with diagbox fault code c1300 and c1301 was displayed on both.
