Thanks!

I agree, this hack isn't for everyone, but for those who can follow along, it might prove to be a learning experience as it was for me. There is no hurt in trying....the worse is you're out a new radio.

Thanks, I'm glad you appreciate my work. Yes it did take a few days after work to film and disassemble the engine. I will be doing more videos on tearing down this engine to show how it works inside, as well as subtopics for other parts of the car, including the tranny. Suggestions are welcome!

Thanks! You made it to the end of the video haha. I did some research and found that there are services out there that clear the info from the SRS computer. I have previous experience working with EEPROM's so as soon as I opened up that motherboard I knew where to head.

I got this sometimes too. You have to double check all your EEPROM connections to the serial port. Depending on the ECU you might have to program it out of circuit.

Yes but you still would have to program it.

Most likely since its similar to the Camry. Just swap the chips.

8th pin is 5V.

Anything that's compatible with the EEPROM should let you edit it.

I'm not familiar with Mercedes, knowing them they've probably over complicated things for the odometer. You might as well drive with no cluster and see if that racks up the mileage.

yes

Pull the cluster. See if mileage increments when you plugged it back in after a test drive.

It goes to 5V on your power supply.

Sounds right.

Glad you enjoyed it.

Its not illegal to change the mileage. It is illegal to misrepresent.

Sounds like you've got an electrical issue.

Use a USB serial EEPROM programmer.
