Odometer stopped working

Odometer
The odometer is an electronic digital display. Digits displayed are illuminated by the odometer backlight bulb. The odometer backlight bulb brightness is controlled by class 2 messages from the BCM to adjust the display for daylight and instrument panel dimming operation. The trip odometer and total odometer will show in this display area. The push button in the lower right side of the speedometer is used to toggle between the trip and total odometer readings. To reset the trip odometer, push and hold the button down for at least two seconds. The total odometer display has six digits with no decimal display. The trip odometer has four digits including a decimal point and indicates tenths of a mile or kilometer.
The body control module (BCM) stores the vehicle mileage. If the BCM fails, the cluster will display the last valid mileage that was sent before the BCM failed. For replacement of the BCM refer to the BCM section of this service manual. Replacement instrument clusters do not require odometer pre-setting before installation. If the instrument cluster is replaced, the mileage stored in the BCM will be sent to the new cluster via serial data, and shown in the odometer display.

Your best bet , take it to a qualified repair shop.

Acura TL odometer trip meter not working Questions ... - Fixya

How many miles are on this vehicle? I ask because the odometers in these car stop working around the 140k to 170k mark. Did the button comeback? Is this the mileage on the digital or analog trip meter?
The process to change the odometer gear is fairly straight forward and takes less than $20 and an hour. Let me know.

Most newer trucks and suv's have a digital odometer. the miles odometer and trip odometer are combinded. By pressing the little button that patrudes from the instument cluster will show you the orignal 226,335 miles. When you press and hold the button while the T__86.6 is displayed will reset the trip odometer. Some people use the trip odometer to monitor times between oil changes and tire rotations.

If the odometer and tripmeter stop incrementing their mile values, then the VSS or vehicle speed sensor is bad or has become disconnected.

Vehicle Speed Sensor OPERATION The Vehicle Speed Sensor (VSS) is a magnetic pick-up sensor that sends a signal to the Powertrain Control Module (PCM) and the speedometer. The sensor measures the rotation of the transmission output shaft or the ring gear on the differential and sends an AC voltage signal to the PCM which determines the corresponding vehicle speed.
TESTING

1. Disconnect the negative battery cable.
2. Disengage the wiring harness connector from the VSS.
3. Using a Digital Volt-Ohmmeter (DVOM), measure the resistance (ohmmeter function) between the sensor terminals. If the resistance is 190-250 ohms, the sensor is okay.

REMOVAL & INSTALLATION Fig. 1: Detach the connector for the VSS sensor
Fig. 2: Remove the retaining bolt for the VSS sensor and . . .
Fig. 3: . . . remove the VSS sensor from the transmission
Fig. 4: Pry the retainer for the VSS gear off and . . .
Fig. 5: . . . remove the gear from the VSS

1. Disconnect the negative battery cable.
2. Raise and safely support the vehicle securely on jackstands.
3. Detach the connector for the VSS.
4. Remove the VSS retaining bolt and remove the VSS from the transmission.
5. Remove the driven gear retainer and the drive gear. To install:
   
6. Inspect the O-ring on the sensor and replace if necessary.
7. Install the driven gear and the retainer.
8. Place the VSS into the transmission.
9. Tighten the retaining bolt to 98-115 inch lbs. (11-13 Nm).
10. Attach the VSS electrical connector.
11. Lower the vehicle.
12. Connect the negative battery cable.

The connector in the back of the gauge could have a bent pin or bad connection to operate the odometer, or the odometer signal is bad from the VSS (Vehicle Speed Sensor).

You need to replace the VSS or vehicle speed sensor. Located on LH, lefthand rear of transmission.

This is an easy fix, sounds like your VSS (Vehicle Speed Sensor) has quit. Verify and test the VSS.

If the speedometer is working but not the odometer it's in the speedometer it's self. replacing the speedometer cluster is the easiest their available on ebay or your local salvage yard.
what happens is the trip odometer wears and sticks, theres a small motor on a circuit board with a plastic sun gear, inside the speedometer housing. it drives both the odometer and the trip odo
the teeth strip off the sun gear and odometer stops.
