Code P2610 Mercedes-Benz Description

This fault code is stored in the Engine Control Module (ECM) when the current flow through the primary winding of the engine control relay is not as expected. The relay will have a constant battery supply to the relay winding and the control side of the winding will be grounded through the ECM. The ECM uses a comparator to measure the voltage drop across a known resistor. Using this value, the system can calculate the current flow within the circuit. The resistance of the relay winding should be approximately 60 Ohms to 80 Ohms. The engine control relay can be responsible for fully powering up the engine control module and other components and/or circuit fuses.
