P2C30Ignition Coil Primary Circuit Fuse A
- Generic OBD-II code · Powertrain
- Turns on the check-engine light

- Can trigger limp mode
- How the car detects it
- On engines whose ignition coils are fed through more than one fuse, the module checks each fuse so that it notices when a whole group of coils loses power. P2C30 points to fuse A. A GM patent explains the reasoning: coils and injectors sit on separate circuits, so after a fuse blows fuel would still be injected into cylinders without spark; the module therefore watches the current through the fuse over a sampling window and cuts the matching injectors to spare the exhaust system. Stellantis uses P2C30 on the 3.0L Hurricane twin-turbo I6 with a separate ignition system control module (ISCM): bulletins 08-205-24 (2025 Ram 1500) and 08-221-24 (2023 Wagoneer) fix it by ISCM software. Expect MIL, misfire and hesitation. Which cylinders fuse A serves is not published.
