From here, the fuel level data can be sent to the instrument cluster or the engine control unit for computing the remaining distance based on fuel level. The signal on Mercedes-Benz must be sent to the rear SAM since it is the closest unit in the Controller Area Network. In cars without CAN / SAM, the signal is sent directly to the instrument cluster via two wires. Here are a few problems caused by a bad SAM unit:
SAM units don’t frequently fail unless there is water intrusion or other problems. All systems on a Mercedes-Benz are controlled via CAN Bus and SAM units any issue you may experience could be due to a defective SAM unit. This is a list of a few possible SAM-related problems.
