Odometer trouble 98 Tacoma

My 1998 SR5 Tacoma jumped from 97 or 98,000 miles to 120,000 miles overnight . A friend suggested it had been moved from miles to kilometers but I can't find any info on that. Anybody got any ideas?

 

The equivalent of 97 or 98,000 miles is around 156 to 157 km. Any chance you've been looking at one of the trip meters instead of the odo.

 

No, I track my mileage with the 2 trip meters so they are under 300 and 600 miles at this time.
I did do a conversion this morning and saw it doesn't add up to kilometers.

 

Weird, never heard of this happening before. Seems like it would be a tough one to explain to a repair shop/dealer too...let us know how it goes, hope it's resolved easily.

 

Disconnect battery, you never know, it might revert back to where it should be.

Again, I never heard thus happening. Please report back.

 

Isn't the Odometer on 1st Gens Mechanical? Meaning the truck would HAVE to be moving to turn the gauge.

 

Not on a '98. Still electronic.
I had my old '98 apart for 6 months. The speedo cluster was sitting on a shelf the whole time. Put it back together and it still showrd the same miles as when I parked it.

 

Ah gotcha

 

The odometer on this 98 is digital not mechanical. The oil change sticker my regular mechanic puts in the window isn't due till just over 100,000 miles. And I get it regularly serviced. I am completely stumped and no I haven't had a stroke. This weekend I will try disconnecting the battery. Will keep you updated.
