2003 Buick Century Odometer Instrument Panel Repair
My 2003 Buick Century PRNDL and odometer lights are dim. I've seen a few
videos on YT explaining that 4 new resistors need to be soldered, how to
remove the dash panels and how to remove the instrument cluster.
I also watched a video on "why and how to properly solder". I've never done
a repair like this and I've never soldered before so those videos were well
worth watching. I also read my newly purchased soldering iron instruction
manual PRIOR TO BEGINNING.
I decided to do this project and recorded my steps to show how easy it was,
the tools I used and the cost. The video is kind of long because I wanted
to show how a person soldering for the first time could easily succeed.
Thanks for watching and the thumbs up.
2001 Buick Century instrument cluster odometer repair
Had a 2001 Buick century with an instrument cluster that had an inoperatve
odometer, PRNDL display. I noticed when I twisted the circuit board that
the sisplay would flash on. Found some resistors with cracked solder
joints, repaired them and it works again.
DIY Odometer Reprogramming
A simple instructional video illustrating how to program your digital car
odometer using simple electronics, a computer with a serial port, some
soldering knowledge and an understanding of hexi-decimal programming.
LINK TO EXCEL SPREADSHEET FOR ODOMETER DECODING:
Most vehicles store their digital odometer reading on the instrument
cluster on a re-writable EEPROM chip. Once the chip is located, it can be
de-soldered from the board and connected to a computer's serial port where
its data can be downloaded and manipulated.
The data on the chip is coded in inverted hex values. Through
experimentation, a pattern was observed that related the values to the
digits on the odometer's LCD display. The data is then edited and rewritten
to the chip, which is then re-soldered to the odometer board and put back
into the car.
Legal stuff: It is illegal to modify or roll back your odometer reading
without full disclosure to a potential purchaser of your vehicle.
