Speedometer stopped working after new battery installed in 4Runnr
I took my 2004 4Runner in for regular maintenance yesterday. Service Advisor called and said mechanic recommended new battery, fuel induction service to clean up carbon build up, replace cabin and air filter.
Picked up vehicle and notice when I got on highway the speedometer was not working. Took vehicle back and after diagnostic was told the cluster was no receiving information. Tachometer works, lights work, A/C works, radio/CD work.
I have had nothing sympomatic to indicate there was a problem with speedometer. Could battery replacement or other electrical diagnostic have shorted out the cluster?

Hey Lyn. Regular maintenance is a scheduled procedure recommended by the manufacturer. They don't check everything every time. If you would want them to do this and create a list of things checked , I am sure they might, but it will probably cost you more. People assume that because they take their cars to dealerships , that they get the best service available. This is not always true. If the battery and alternator are bad again, I would go back to mieneke and complain to them. they are nation wide and all of them should honor a warranty. What mieneke told you was probably opposite of what happened. The alternator was probably putting out to much of a charge and toasted the battery. Weak batteries wont kill an alternator. At least I have never seen or heard of it. As far as warranty issues, it is pretty much your responsibility to bring them up to the dealer. Again if there are specific things you want checked at maintenance time take a list and have them sign off on it. If they already have a list ask to see it and when there done ask for a copy. you pay for it, so they should give you one. I suggest that if you have an issue come up with repairs, to post on here and get some insight to what may be going on with your car. There are a lot of good mechanics on this site. Randy
You may have a bad Vehicle Speed Sensor [VSS] which is mounted on the transmission. This sensor tells the computer, transmission, and dash how fast you are going and if the signal is lost then the transmission won't know when to shift and the speedometer will quit working. There should be a related service code stored in the system that will help with the diagnosis.
I finally broke down and took my truck to the dealer. It took them two tries, but they finally figured it out. It turned out to be the wiring harnes for the shift lever. When it exits the steering column, it was being chafed, and eventually wore through a wire and was intermittently shorting. It would blow a fuse (don't remember which one - I think it was on the bottom row, third in from the right. 20A). It stopped the alternator from charging too. They replaced the shifter harness and the problem went away. I did get a ticket while my speedo was inop however.
