Hi,First of all let me apologise for my ignorance of electronics, buthopefully some kind sole out there may take pity on me and be able tohelp me with my problem.The problem I have is with the instrument cluster on my car which hasrecently developed a fault. After a lot of Internet trawling I havediscovered that the fault is caused by the MC68HC908AZ60 2J74Y chip,this chip is responsible for driving all of the gauges, dials andlamps etc.The fault takes the form of the gauges & warning lamps pulsing &flashing when the ignition is turned on. This fault condition can lastanywhere between 20 seconds & a few minutes before the instrumentsreturn to normal operation. My research has turned up the fact thatthe fault is temperature related & when it's cold the fault persistsfor longer than it does when it is warmer.Is it possible to read this chip if it were removed from theinstrument cluster?I have read that the chip is code protected but then I have read ofthem being read so I'm a bit confused?If it can be read can I buy a new chip & programme the dump of thedefective chip (if it's possible to get one) onto the new chip?What would sort of programmer would I need to do this?Thank you & here's hoping for some advice with this problem.Regards.
