So ive had this check engine light on my dash for some time and it gave me a p0703 code. This code has been there for god knows how long. I have tested the brake switch and changed it but still no change. Until one day is magically went away after i adjusted the brake pedal.... Buttttt it came back in after a week with the same goddam code. I jst tried removing the battery and drain the electricals, left it for 15mins and the code is still there. Ive also checked the new brake switch and its working fine. Everyone of my brake light and fog lights are working and ive even added a relay to the brake switch for my brake lock. As i though that the brake lock is drawing too much current. I even removed the brake start that was added with the physical brake lock.
