Put the switch on the tc to lock it manually. Work great but when I check it for a code by turning the switch on an off three times p0700 will come up then go away and pdone will stay on. What is going on.

 

Computer is seeing a problem. Did you put the resistor in? Or did you do it at idle? Could have caused the codes. Looking to put that in mine this weekend too!

 

No I didn't put the resistor in . Don't know what you mean by idling in park.

 

Did you flip the switch any time other than driving down the road?

 

No it was after 40mph. went and had code removed at dealership and ask what the code was after looking on DC sight the only thing that came up was lack of power and suggested that an up date program be done. On the way back home stop several times not using switch no code then used switch got code p0700 again. Put a 33k ohm 1/2 watt 5* tolerance resistor in ground wire and left jumper in relay and it didn't work at all. Will it hurt truck if the code stays and still use switch because I really like the options the switch provides.

 

OOPS just did search on tc switch on this forum and I used wrong resistor it needs to be 33ohm not 33k ohm I guess I had a senior moment. Still would like to know about the code if it will hurt to continue run truck with it. Will try using resistor and no jumper on relay if someone has already try ed this on 03 48re let us know.

 

Well it works without jumper just resistor
