Clarion pu 2294 dump - GSM-Forum

Hello,
my son bought recently bought a car with a clarion PU 2294 A(C). This radio was not working (earh not connected) and when I've connected it it asked me for a code.
I'd like to know if it's possible to get the dump of the 93c46 rotated eeprom through the RD1 connector or if i must dismantle the radio to access the chip.

Thank you in advance for your answers

Hi, see this part of service manual. Look connectors... data and data- connected to VAN chip... I think better desolder chip and read. Its my modest suggestion

Problem solved.
I've found the code on the left side of the radio case.
In my case there is a list of letters and numbers printed on the case (looking like a stamp): the radio code corresponds to the third, fourth, fifth and sixth caracters (something like XX YYYY ZZ where YYYY is the code)
Maybe it's only luck but if it can help someone...

I can't put a picture since the stamp is nearly erased and the photo doesn't give anythig readable.

Thanks for the help i've found on the forum

ps : how can i show the problem is solved in the title of the thread ?
