Usually caused by failed alternator. If you have a voltmeter, check voltage at battery with engine running. It should be at least 14 volts. If not, replace alternator. If you don't have a voltmeter, remove the alternator and take it to the parts store for testing. Let me know if you have questions.

With or without your foot on the brake pedal? Did you have the ECU scanned for codes? You can have diagnostic codes in the ECU without having a light.

It sounds like the alternator is going bad. I reccommend pulling the alternator and having it checked out, most auto stores do this as a free service. There could also be another problem on the rpm thing but I would start with alternator and inspect all other pulleys that the belt rides with. Good luck.

Car wont show driving speed not does the odometer work battery light keeps coming on while driving


Sounds like an electrical problem. It may be the alternator, starter, or battery when that light comes on. As far as the speedometer goes, is has a cable and it may be broken unless it's a digital speedometer. Take it in for a diagnostic test to see what's going on. That should fix your problems.

Battery light means the alternator is not charging so if you keep driving it eventually the battery will die. The brake light may be on if the emergency brake lever is pulled even a little bit.

Changing parts doesn't necessarily mean the replacements are working. Measure the voltage on the battery with the car running, you should see 13.7 to 15.1 volts. Turn on the headlamps, rear defogger, etc (put the system under load), you should stay in the same range.
Assuming all of your electrical connections are good, the symptoms point to the alternator/regulator - these are integrated into one unit.
