The good news: Tire shop gave me a free rebalance because I had driven only 150 miles in the last 3 months.
The bad news: My odometer quit working 150 miles after I had the wheels balanced the first time..
Went to run the Function Test (A7, press button 3 times), but I found the wire already plugged into A7. I must have forgotten to unplug it when I changed the oil. I figured that this might be the cause and unplugged it.
Next day, odo still NG. Tonight: Ran the Function Test.. All the needles point where they're supposed to, but the odometer doesn't even twitch. (Speedometer works, so it's getting the the speed input signal.
Leaving A7 plugged in shouldn't have done it, since it just goes directly to an IO pin on the combined instrument microprocessor.
I'm hoping it's just a cracked solder joint. Has anyone disassembled the combined instrument enough to see how the odometer motor / solenoid is wired up? Is it driven directly by the main board, or by electronics within the speedo assembly itself?
Now to find out how to remove the thing from the dash.
