My 2004 Honda accord v6 with navigation system has randomly been having the TCS light come on and within seconds the light comes on telling me that my driver side airbag is off & my A/C stops blowing out cold air. Since this has happened many times...I am assuming that they all have something to do with each other. Sometimes the needle for speed and rpm will also go limp...but car continues running and moving. I have to pull over and turn the car off and then on for the A/C to come back on. Also, I have noticed on the Navigation Screen for Trip Computer it does not register any RPMs or Miles to go? ....Any advise?

 

There is a very complex Multiplex Integrated Control system on the 4-cyl. car, and probably on V6 as well. If you want to learn how to diagnose and repair, you will need to purchase a shop manual and spend some time studying the manual.

If you're not up for that, Honda specialty shop or dealer is best option.

good luck
