[QUOTE=nucor;2246359]thanks arthur i got the codes from the box with the blinking light. i erased the codes but code 19 came back could you tell me what that code is. i will try the fp reg tommorow.

also what fuse should i check in the base module.

All 4.


Code 19 can be a troublesome code on that chassis. It is a fuel adaptation code and they did not allow enough % of limit. So, they can be modified.

But, before I get into that, check the FP regulator. That , and vac leaks, are common causes of an adaptation limit code. Check those first.

You can re-set the memory adaptation back to mean , but you will have to build the led tool for that.
Are you familiar with the tool???
