Hacking odometer

The odometer digital is driven off a circuit board that is part of the instrument panel. It is illegal to tamper with an odometer. Multiply by 1. You need to let us know if it has a digital readout, or if it has the traditional mechanical odometer.

Its not illegal to change the digital odometer on a car. Any digital odometer can be program. I can program a digital odometer from the oldest to the newest cars. Some cars I need to have them with me, but most can be sent over the mail. Go to usaodo. All cars have either an eeprom or a microcontroller that saves it in memory. You only need to know how to program the chip or the processor and what memory to change, what to change it to.

Its not cheap equipment and software, but to have it done is cheap. Changing a digital odometer is not illegal, making profit off of it or not disclosing that it has been changed is illegal. I'm pretty sure that's illegal. You can't. Besides, it's against the law to tamper with the odometer. I have a Dodge Stratus Coupe V6 and mine is a digital odometer located right under the speedometer. It is not clear from your question whether the odometer is mechanical or digital.

If it is digital, this is likely the beginning symptoms of a cracked solder joint on the circuit board that provides power and mileage information to the odometer display. You can not as it is a computer chip. Also, it is against the law to defraud. Not with out the equipment and knowledge to rewrite the computer programming. Yes there is. It is digital, and seen next to the odometer reading. Mostly all the vehicles that I have worked on with a digital odometer cannot be lowered.

Their is an actual manual odometer that reads to the engine computer that sends digital readout to the odometer, that cannot be reset or changed if you were to try to it would disable the vehicle and would need to be taken to the manufacturer garage for service to reset computer but would still give old odometer reading.

If the computer were to come out of another car the odometer still wouldn't change. Government is very very strict with odometers these days. If the digital odometer is not displaying its readout or is working intermittently it is a common occurrence that there is a bad solder connection on the instrument cluster. When the digital odometer is not displaying its readout or the digital odometer displays intermittently this problem is frequently reported along with the vehicles tachometer not displaying any readout or working on an intermittent basis as well.

The link below shows the steps to repair a bad solder joint on an instrument cluster. It is fully illustrated and not too difficult, took me about an hour from start to finish. It is highly unlikely that a digital odometer would show a one in front of the correct mileage. It sounds like someone is trying to sell you a car and tell you it has less mileage than it really does.

Change the vehicle!? I really don't know what you mean. Code reader? Need to hack that. From there he was able to decode the traffic and figure out the commands he needed to monitor.

The last piece of the puzzle was to write his own Android code to watch for and react to the steering wheel buttons. You can check out the code at his repository and see the demo after the break. Perhaps the reason odb-ii is used rather than ODB-II is because persons not need to be concerned about using the proper case when making use of tags. When ever I take the time to tag bookmarks, I use lower case for ancronyms. That has been my experiance anyway, YMMV. Yea I remember the reason it was rejected is that old old post or comments to them would have been lost.

Eagle ceased to exist as a marque as of Slight correction. I make the same mistake all the time, sadly. The odometer is a completely separate device even if digital. I can think of another reason for people to do that… if the vehicle had a , mile powertrain warranty and the transmission died at , miles….

Nice job, I always wanted to do this exact thing. Unfortunately, the car I had with steering wheel controls for the radio was totalled in an accident. The clusters require a special clip or jtag connection to reprogram, and yes, there are legitimate reasons to reprogram mileage, as well as fraudulent purposes.

Working in automotive and collision repair, I can tell you that a lot of clusters get damaged, or burn out and need repairs or replacement. The old method was to replace the cluster Mechanical with a new or salvage unit, and to put a discrepancy disclaimer decal on your door pillar. Now the units can be reprogrammed to show the correct mileage, which can be used illegally, or can be used properly to revert to the stock mileage. I just have a problem with the whole idea of adding a computer screen to a car specifically one accessible to the driver in the first place.

If texting while driving is dangerous which it obviously is , how much more dangerous is this? Drivers need fewer distractions, not more of them.

This hack is not about adding screens to a car. This hack is about controlling an android device without having to look at its screen.

I added a tablet in place of my stereo in my car, and I will say this… I probably look at my tablet LESS than I looked at the factory stereo. I have it set up with big fat easy to hit buttons, and voice commands handle a lot. There is a huge difference between texting and accessing a control system.

I am in the process of adding a tablet to my truck to; replace the radio; climate control system; add a secure start system…. I understand that texting and driving is a huge distraction and dangerous, but this is really nothing like that.

Granted good drivers are a rarity. When you try to idiot proof something all you do is create bigger idiots. Was not hard at all to make the changes.

Oh and wasting time sniffing it where a google search would have turned up the whole protocol…. Found this in But still a nice hacking achievement. I humbly beg to differ. In reality, however, the manipulation of CAN bus makes odometer fraud just as easy, and [Andras] is here to show us exactly how easy with a teardown of a few cheap CAN bus adapters.

We featured another project that was a hardware teardown of one of these devices , but [Andras] takes this a step further by probing into the code running on the microcontroller. One would imagine that basic measures would have been taken by the attackers to obscure code or at least disable debugging modes, but on this one no such effort was made. Analyzing the codes showed identical firmware running on both devices, which made his job half as hard.

It looked like the code was executing a type of man-in-the-middle attack on the CAN bus which allowed it to insert the bogus mileage reading. Many of us now carry a phone that can give us detailed directions from where we are to a destination of our choosing. This luxury became commonplace over the last decade plus, replacing the pen-and-paper solution of consulting a map to plan a trip and writing down steps along the way. Given a starting point and a mechanical link to the drivetrain, these machines can calculate miles traversed and scroll to the corresponding place in the list of instructions.

Because a bus runs a fixed route, it is possible to determine location of a bus given its odometer reading transmitted over radio. This was useful before the days of cheap GPS receiver and cellular modems. But the odometry systems would go awry if a bus rerouted due to accidents or weather, and obviously the same would apply to those old school systems as well.

Taking a detour or, as the article stated, even erratic driving would accumulate errors by the end of the trip. One of the patent diagrams explained the solution is to hand the device to a passenger to read.

The limited utility relative to complexity and cost is probably why those systems faded away. But the desire to solve the problem never faded, so every time new technology became available, someone would try again.
