I worked on the svs and did option B. I had constant three amigos and my mechanic had to remove the three amigo with his test book after option B.
one week later, they are back and it looks like a hard fault. My switch tested fine so figured it was in that two pin socket. Any other idea why the amigos are back. I checked my wiring to make sure ground was grounded too.
Thanks

 

Read the code again. And recheck your ground. Some guys had had to create a new grou d for it to work.

 

Is there any way I can remove a hard fault with my code reader? It appears after testing I have continuity between the engine block and the ground screw.

 

i have a 3 amigos hard fault too, 2000 disco, i did the bypass, i dont have a code reader and way to clear the codes, in baltimore md is anyone has a code reader for this.....
