I removed then reinstalled cluster and mileage changed.

I removed my cluster to paint the dash, and the mileage changed from 172,XXX to 272,XXX. Only the first number changed, every other number remained the same… How do I get it back to the actual mileage?

My car has 172 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
The vehicles body control module should have the correct mileage stored and you will have to bring the vehicle to the dealer to have the instrument cluster reprogrammed to read the correct mileage. If the body control module has lost its programming and the instrument cluster cannot be programmed, special permissions will be required to reset the odometer to zero and a notice will have to be attached to the vehicle stating the last known mileage and the technician who set the odometer back to zero and this label may not ever be tampered with under federal regulation.

Can I drive my 2004 Silverado without the instrument cluster? Yes, you can drive your Chevy Silverado without an instrument cluster but only for a short period of time. If you are on a long trip, it is not recommended.
Push and release the Sel/reset button button 3 times repeatedly. The instrument cluster begins its self-test. Each successive press of the Sel/reset button initiates a new cycling of all the gauges. To end, turn the ignition switch to OFF, or vehicle speed exceeds 1.5 mph.
If your gauge cluster isn`t working, you should replace all of the bulbs and check your fuses. If you can get to the fuse box, check all of your fuses. If you`re not getting any power to your instrument cluster and your gauges work when headlights are on, you may need to replace the instrument cluster itself.
All you have to do is turn the key to the run position (do not start the vehicle) and push the reset stem five times. Make sure the trip odometer is displaying and hold the stem in for 30 seconds.
Can I replace my instrument cluster? Older cars without a mileage storage chip can simply have their clusters swapped out without any programming. Newer cars with the mileage storage chip will require that you have the dealer perform a VIN relearn procedure.
It`s Not Illegal To Replace The Instrument Cluster

In modern cars, the mileage is stored electronically in your vehicle. This post goes into more detail about retrieving accurate mileage. It`s completely legal to replace the instrument cluster in your vehicle.

In modern cars, all of the sensors are connected to the ECU, and the ECU sends all the relevant information to the instrument cluster. Instrument clusters are connected to the vehicle with a wiring harness.
Instrument cluster fuses are an important part of the vehicle`s electrical system and should be checked regularly. While instrument cluster fuses are generally reliable, they can occasionally cause problems, including failure to start, erratic speedometer readings, and dash lights not working.
The ECM or BCM has a bunch of wires running to sensors and lights all over the vehicle. The way this setup works is the ECM or BCM gets information from the sensors or lights all over the vehicle. It then sends the information to the instrument cluster, which displays the information to the driver.
If it does, the odometer won`t show an accurate representation of the mileage on your vehicle. That`s a valid concern. So does changing an instrument cluster mean changing your mileage? The short answer is no.
A digital odometer can be rolled back by removing the car`s circuit board to alter the odometer reading. Aside from that technique, fraudulent individuals can also use rollback equipment to tamper with these devices.
ECU re-programming is not required because most repairs are done on the hardware parts and not on the software programming. Therefore, the programming of the ECU will never be altered.
The price ranges from $250 to $400 if you purchase from a cluster company.
Yes, most instrument clusters are interchangeable. This means that you can change the factory one for a new cluster.
Can I drive my vehicle while the instrument cluster is out for repair? Yes, you can still start and run your vehicle without the instrument cluster.
The engine control unit counts all of the pulses and keeps track of the overall distance traveled by the car. This means that if someone tries to “roll back” the odometer, the value stored in the ECU will disagree. This value can be read using a diagnostic computer, which all car-dealership service departments have.
Most modern vehicles have a fuse box located under the hood and another under the dashboard. The fuses for your instrument panel lights and the gauge cluster should be located under the dashboard or behind a panel near the driver`s side door.
How do I reset my Chevy fuel gauge? There are two ways to reset your Chevy fuel gauge. For newer vehicles equipped with the instrument panel cluster, simply push and hold the button on the end of the turn signal lever for about 10 seconds. You can also try disconnecting the positive battery cable for about 10 seconds.
Press and hold the “Trip/Odo” button again until the Odometer says “1.” This means that the reset process has begun. Keep holding the button down while the fuel gauge resets. Release the “Trip/Odo” button once the reset is complete. You`ll know the process is finished when the Odometer display moves back to normal.
ECM stands for Engine Control Module, and ECU is short for Engine Control Unit. These two acronyms represent the same component and are used interchangeably.
This cluster is pre-programmed for a 100% plug & play installation. After purchase, a short processing time is required to expedite the programming process, to deliver the cluster customized to work in your vehicle.
The speedometer fuse is located in the fuse box and controls the power supply to both the speedometer and odometer.
No, you cannot put just any gauge cluster in any car. The cluster needs to be compatible with your car`s make and model. Otherwise, it will not work properly.
An inoperable instrument cluster is another symptom of a possible issue with the vehicle`s instrument voltage regulator. If the instrument voltage regulator fails completely, power to the cluster will be disabled and it will cease to function.

I removed the needles in my gauge cluster. Now the fuel and temp shoot up and stay there. My speedometer needle also reads wrong.
ANSWER : For the fuel and temperature gauges check the wiring to the gauges and see if they are connected properly. For the speedometer, the needle maybe in the wrong position and reading incorrectly. When taking off the needles to the gauges, the gauges could have disturbed the contacts inside the meters and caused the wiring to reverse themselves to give a false reading. If you are unable to repair the gauges, then I suggest replacing the gauges. If you need further assistance with your gauges not working properly, then seek out a professional, such as one from Your Mechanic, to help you.

Do I need an oil change? 2011 Infiniti EX35 has less than 2000 miles on synthetic last changed 5 yrs ago. 3500 total mileage.
ANSWER : Oil changes are essential to an engines performance and the longevity of an engine’s life. I recommend having an oil change either every 4 months or 5500 miles. If your engine oil has been in the engine for more than a year, then the toxins in the engine will mix with the oil making the additives weak and unable to clean the engine properly. Since the engine oil has not been changed for 5 years, I recommend that the oil and oil filter is to be changed. If you need further assistance with your oil change, then seek out a professional, such as one from Your Mechanic, to help you.

ANSWER : The windows can be repaired if you request a window regulator/track inspection. For door lock issues, please request door locking system diagnostic/repair. The engine operating condition problem you are having should be diagnosed as a possible misfire although the mechanic would consider a fuller slate of possibilities in order to get to a resolution (i.e., pinpoint the fault). For example, you could have an issue with one or more ignition coils, a sticky fuel injector, the throttle position sensor, a vacuum leak, faulty oxygen sensor, and so forth. If you request the misfire diagnostic, the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Is it possible to remove Bracket bolts without removing caliper pins?
ANSWER : The complete bracket and caliper can be removed this way. I have seen this many times where the caliper retainer slide bolt seizes. The reason is no one lubed the slides and pins when they did the brakes in the past. This was avoidable if they lubed them on previous brake jobs. You can also purchase a new caliper with the bracket in most cases as an assembly. If you want to have a mechanic assist you with this, a certified technician from YourMechanic can come to your car’s location to inspect your suspension and help perform this task.

Have original spark plugs in my 2009 Taurus with 129000 miles. Car runs good, gas mileage good. Should they be changed?
