Code P0617 2018 Chevrolet Silverado Description
The P0617 diagnostic trouble code (DTC) for a 2018 Chevrolet Silverado indicates a problem with the Starter Relay Control Circuit High Voltage. This code is triggered when the powertrain control module (PCM) detects that the voltage in the starter relay control circuit is higher than normal. The starter relay is responsible for sending power to the starter solenoid to crank the engine. When the voltage in this circuit is too high, it can lead to issues with starting the vehicle or even cause the vehicle to not start at all.
Common Causes of P0617 2018 Chevrolet Silverado
- Faulty starter relay
- Damaged wiring in the starter relay control circuit
- Malfunctioning PCM
- Poor connection in the circuit
- Corrosion or loose connections in the circuit
