P1602 Fault Code: Understanding The Description And Troubleshooting Steps
The P1602 fault code indicates that the Engine Control Module (ECM) is receiving low supply voltage from the battery. This means that even when the ignition switch is turned off, the ECM is still receiving power from the battery. This power is used for various functions such as storing diagnostic trouble codes (DTC) and maintaining the air-fuel ratio adaptive control value memory.
When the ECM does not receive sufficient voltage from the battery, it can lead to issues with the engine’s performance and overall functionality. It is important to address this fault code promptly to prevent further damage to the vehicle.
A professional diagnostic scan should be performed to determine the exact cause of the low supply voltage and to implement the necessary repairs.
