Code P0698 Suzuki Description

The P0698 diagnostic trouble code (DTC) for Suzuki vehicles indicates a problem with the 5 Volt Reference 3 Circuit, specifically indicating low voltage. In modern vehicles, the Engine Control Module (ECM) or Powertrain Control Module (PCM) sends out 5-volt reference signals to various sensors and components within the vehicle. This voltage is crucial for proper operation and communication between these components.
