Odomere is not workin

Speedometer
The instrument panel cluster (IPC) displays the vehicle speed based on the information from the body control module (BCM). The engine control module (ECM) calculates the vehicle speed based on the controller area network (CAN) serial data message indicating the wheel reference speed from the electronic brake control module (EBCM). The ECM sends a CAN serial data message to the BCM indicating the vehicle speed. The BCM sends a class 2 message to the IPC indicating the vehicle speed.
The speedometer defaults to 0 km/h (0 mph) when any of the following occur:
• The EBCM detects a malfunction in the vehicle speed sensor circuit.
• The ECM detects a loss of CAN communications with the EBCM.
• The BCM detects a loss of CAN communications with the ECM.
• The IPC detects a loss of class 2 communications with the BCM.

Having the vehicle scanned for codes would probably point you in a correct diagnostic direction .

You found the right place right time buddy.. i know a lot of websites for repairs and manuals that can really help u..

I had a Lincoln which did almost the same thing. On my car it was the Alternator shorting inside its casing. You can get a free test at Autozone or Oreillys on the car.

Now mine did not return to normal when I put it into Drive. So on your car you may have an Electrically shifted transmission. I would think if the Alternator passes its tests, you have a short in the shift control module which is shorting the Alternator and its Regulator inside..

My Speedometer would read 60mph and the Odometer would count the miles when the car was sitting still. I replaced a Digital dash to no avail and then found the Alternator was the reason my Speedo and Odometer were acting up. Immediately after changing the Alternator all problems stopped for me.

possible short in dash. have you put an after market radio in it?

From your description, the instrument cluster has a short. These cannot be repaired, only replaced. This has become very common on 2000 and later vehicles, regardless of make.

possible short in wiring, dash panel, or sending units

More than likely your lead gear for your odometer is spinning on the shaft and not advancing the odometer or tripometer. You will need to remove the speedometer from the cluster to verify. once the speedometer is removed you will find a metal/gray colored gear next to the odometer digits. Take a small flat tip screw driver while holding the odometer digits in place with your finger, try and spin the gear. If the gear spins this is your problem. OdometerGears.com has the three different sizes of gear for you to fix it.

I had the same issue with my wife's 01 beetle and it ended up being a bad alternator.

Odometer is turned by a mechanical gear wheel, which is the likely culprit.

I found that with mine, it is the key switch. If I start the car or just turn the key on and the a/c or signals do not work, turn the key off and back on. It may take more than once but that is what works for me. The odometer works on mine, but the tripometer does not, and has not for a long time. Mine only has 68K original on it. Does that help?
