Common Diagnostic Steps
OBD2 Code: P0617
Description: Starter Relay Circuit High
- Check the battery voltage and connections to ensure they are clean, tight, and free of corrosion.
- Inspect the starter relay for any signs of damage or corrosion.
- Test the starter relay by swapping it with a known good relay if available.
- Examine the wiring and connectors in the starter circuit for any signs of damage, wear, or loose connections.
- Use a multimeter to measure the voltage at the starter relay control circuit to verify it is within specifications.
- Check for any blown fuses related to the starting system and replace them if necessary.
- If equipped, inspect the ignition switch operation and its connection to ensure proper functionality.
- Consult vehicle-specific repair manuals or databases for additional diagnostic procedures specific to your make and model.
