Troubleshooting Clock

My clock and fuel rangefinder is on the top center of my 2007 DB Toyota Tundra. When I purchased this 5 years ago the rangefinder worked well, along with the clock. Now the RF IS not accurate, an the clock losing time up to 3 hours. Is there a fuse that could be blown or something else?

 

How old is your truck battery? If it's more than a couple years old, get it checked and/or replace it. These trucks hate bad batteries.

 

The official term is “accessory meter” if its coming on, doubt it a fuse problem. Way back when my 2007 wouldn’t keep time and the dealer replaced the accessory meter under warranty.

Did you recently unhook the battery? This will cause the truck to forget your avg fuel use and the range will be way off until you drive it for a while
