that does not look good, read back, and remember 16 bit.

Hi,

Reading is correct.

Thing is its new SW.

Not a 93C66 marked eeprom.

Eeprom is marked as RH66...

New algo...

**daremen** · 23rd February, 2018, 08:28 PM

You are right, EEPROM marked as RH66

Thanks, for the info Landetos, I have an idea, but to confirm, i need other dump.

Take the eeprom off the board, then power up the cluster again and the original mileage will still be displayed (in KM this time if your cluster is in miles). So either there is other memories on the board or the absence of the eeprom makes the spansion cpu display the last image of the mileage. Anyways here's a file for you. Load this dump file as is and see what happens or if you find something let us know.

Thank you.

Hi
Here is another dump with 26929 miles. I changed line 50 miles doesn't change. Any ideas ?? Chip says RH66 reads fine as 93c66.
I need 5500 miles. If anyone has power up let me know cause I have cluster coming back and we can play to figure this out.
Thanks

Line 50 calculates to 25881 if you use the Denso algorithm, it may be the trip odometer.

Need to put a few Km on it and read again so we have a good comparison.

**testit34** · 17th March, 2018, 10:15 PM

Hi
Chip is Tssop 93c66 labeled RH66. MCU is an ARM. Dump is already posted
Thanks
