check for bad capacitor... check for 5v reference voltage..... check can hi-lo for 2.3- 2.6 volts if you have old computer for parts laying around replace the can transceiver 8 pin IC ... TJA1050


but before you go into the ecu make sure all powers and grounds are present at ecu connector....

make sure to check computer datalines with ecu connected and also with ecu removed...



If this helped dont forget press thanks button and some reputation

see that Chip i measure it provide 5v and 3v to the flash and Mpc and Ecu read clear and CAN bus receive those voltage normally but no 5voltages on Sensors ....

High fan speed, leads to internal MCU error or does not recognize the mapping area.

Correct, in my case, under the MCU the tracks were all broken.
