The code P1620 for a Suzuki Maruti indicates a fault related to the Engine Control Module (ECM) or the vehicle's immobilizer system. It typically signifies that there is a communication issue between the ECM and the immobilizer, which can prevent the vehicle from starting. Diagnosing this code usually involves checking wiring, connectors, and the immobilizer system to ensure proper functionality. If necessary, reprogramming or replacing the ECM or immobilizer may be required to resolve the issue.
