For my work here https://myimiev.com/threads/etacs-config-modification.5698/
i had need of the information of the Hardware that is inside the Mitsubishi ETACS.
Now for my part i know what i have: A Micro controller with 384KB storage and a additional 32KB SPI chip. There are numbers on the pictures and a parts list so the most important parts on the ETACS are publicly documented. I was not able to find those information somewhere else online.
When someone is willing to do some research on their own, it would be nice to get pictures of other PCB's and a list of their parts soldered on their PCB to compare if there are changes between the model years.
Parts list of Mitsubishi ETACS:
Solder side:
1 SOP-8 TLE6251DS CAN Transceiver
2 SSOP-14 TLE42994E 5V Low dropout voltage regulator
Top side:
3 SOP-8 TLE7259-2GE LIN Transceiver
4 SOP-14 PCF7991AT RFID Basestation
5 TQFP-100 UPD70F3376AM2(A1) NEC V850ES/Fx3 32-bit µC 40 to +110 °C 384 KB with POC
6 SOP-16 TDA62004AFG 7-channel Darlington Sink Driver
7 SOP-8 "S25A32" 25A320 Automotive 125°C SPI EEPROM
8 SSOP-14 TLE42994E 5V Low dropout voltage regulator
9 ECOPACK-24 VND5025BK 2-Ch high side driver with current sense
RF module (the green PCB that is soldered vertical to the main PCB):
SSOP-28 TDA5210 FSK/ASK Superhet Rx
For my task i know now, that if i would solder the RF module out, it wont do anything to the TPMS side. There does not look to be any detection if this RF module is soldered in or not. The RF module just transmits the data it gets further. It does not do much with the data on its own. So when the green PCB is soldered out, it would be same like when you remove the antenna (the vertical soldered in metal). It wont receive TPMS any more but still report the error code.
I think at next step i would take a look at the content of the SPI chip when its soldered out. I think for reading out the 384KB from the controller i would have to do some more research about required software. Maybe PCMFlash could do the readout but i would prefer to find some OpenSource software for the task.
