Hi, my name is***** your mechanic automotive expert, and I will be happy to assist you today. In some cases, I may need more information to assist better. I apologize for any delay and would like to know whom i am having the pleasure to chat with.Dear customer, first the ecu and the Sam module are different modules, I see that you have a signal problem in the transmission module, so i understand that it is the gearbox of the ecu. it could be a problem at the transmission module level, you have to be careful with this. There may be an override of the module signal even the module may need to be replaced.
Dear Mario, it is a pleasure to assist you, do you have access to a diagnostic equipment with MB Star software? We have to examine what are the codes that you are presenting that are causing these indicators to light on the instrument cluster.
It is likely that what you are presenting is a limp mode what seems strange to me is that you are not getting a signal from the transmission. We would have to observe what are the values that you are not receiving to evaluate if it is a problem at the level of the valve body and solenoids
Dear customer, i apologize for my delay i had a connections problems and i could just get back.
From what I see the codes that you are holding from my position are due to what software of the diagnostic equipment does not have access to several modules are CAN communication problems. What does concern me is the cable that you tell me is not receiving or emitting a signal.
It is strange dear customer, all the codes are from CAN communication problems.
The CAN bus (Controller Area Network) is an automotive BUS developed by Bosch, which allows microcontrollers and devices to communicate with each other within a vehicle without a host computer.
It is basically the way in which signals are transmitted. All the error codes that you are presenting are related to this communication.
Dear customer personally I would look for a more suitable diagnostic equipment, second if the problem persists the fault will be at the electronics level of the main computer, third I would discard the electrical wiring.
