Freightliner Columbia 2007

[Dr. Zoidberg]

hi everyone, today I was with a columbia truck, detroit engine, this change the km, it shows well, but after 5 switch, the board shows ------- and ICU 140 error appears, I assume that must be a problem of synchronicity with the PCM, can someone guide me with respect to the steps to follow ?, I have doubts if this tachograph, is the fault, or if rightly the problem is that I must do board and PCM.

how do you did the ecm ?
Hi mate, no, just a board, do you know how to do the ecm ?, or do you know what is inside? Is eeprom or mcu?

the best way is using a can bus analizer, to comand the mcu to read / write data
