The cruise control does not work at all. It did and then just stopped in spite of trying everything book recommends. Fuses have been checked with a voltmeter and have not touched modules. No specific fuse or module for this problem

The emergency brake was working and stopped. Fuses have been checked, but there does not seem to be a specific fuse for this. Is there a module for this? I will change if it is required. I am at a loss as to why these do not work and what to do reset them.

Thanks, Liz

Hello,

These two problems should be related the ABS system is the parking brake as well. There is a fuse and relay that ruin the system since you checked the fuse the 15 feed relay is next.

Here is the wiring diagrams for the system and the relay location so you can run a test.

Check out the diagrams (below). Let us know what happens and please upload pictures or videos of the problem.

Cheers, Ken
