Pull it straight up out of its socket.
You can erase data from an EPROM chip, simply by using the MProg 2.8 software. This can be found on the White Box Robotics website, along with step by step instructions on how to use it.
Majority of the time the problem is in the ignition key chip or ignition lock cylinder
Power On Self Test instructions are part of the BIOS that is stored in EPROM. Some of the parameters used by the EPROM are stored in the BIOS CMOS chip.
EPROM or Erasable Programmable Read Only Memory was invented by Engr. Dov Frohman. It is a ROM-type chip that can hold data from 10-20 years. It is different from PROM because it can be programmed more than once. An EPROM programming is erased only through exposure to ultra violet light. The EPROM is configured or reconfigured using an EPROM programmer.
it is what is known as eprom it basicaly stores information by programming a read only chip
It stands for Erasable Programmable Read Only Memory. It's basically a computer chip that can have information programmed onto it - which stays on the chip even when the power is turned off (unlike RAM which is erased when you turn the computer off) The EPROM can be re-programmed by erasing the current information and re-writing new information to it.
On-chip memory is a memory that resides on microcontroller itself. e.g RAM. It may be one of the Internal RAM or Special Function Register (SFR). Off-chip memory is external ROM or EPROM.
not for sure, but sound like something messed up in the dual climate control chip.
Well, honey, after the microchip is manufactured, data is typically programmed onto it using specialized equipment that can write and read information to and from the chip. This process is usually done in a controlled environment to ensure accuracy and reliability. So, in a nutshell, data gets on the microchip after manufacturing by writing it onto the chip using fancy machines.
02 cadillac deville wont crank or start the entire dashboard illuminates and everything work when the switch is on seems like it wants to crank but doesnt. I had a problem for years with my 1991 Caddy and kept changing starters for a while. My problem was that I wasn't getting a good read on the security chip in the key. Next time it happens: turn it off, take the key out, wait at least three minutes and try again. Check your manual to see if that is still the procedure. By the way I decided to live with it. Every start is a roll of the dice.
On my 1996 Deville, the problem was one of the two fine wires coming off of the ignition switch that lead to the computer that reads the chip in the key had broken off. According to the dealer, this is very common. The solution is to have the ignition switch replaced. Dealer cost aprox. $400.00. I later found a locksmith that said they do them all the time for about $250.00. I was told that although the car may restart for awhile after you get that theft system warning, eventually, it will not and will have to be towed.
you have to purchase a new EPROM chip for your ECU!! it's all computer controlled!!! AT
