P2AF8Starter Relay D Control Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Needs a drive cycle to confirm a fix
- How the car detects it
- P2AF8 is logged when the control line of starter relay D shows a short to ground. Depending on whether the module switches the coil on its ground side or its supply side, the relay then either sits permanently energised or can no longer be operated. Stellantis lists P2AF8 in STAR case S2108000038 for the 2020–2021 Chrysler Pacifica, among codes such as U0100 and P0627 that arose from spread or bent terminals in the power distribution centre connectors, together with no-start and many electrical complaints; which relay the code covers there is not stated. Beyond that no maker publishes a set condition. For comparison, GM flags 0.5 Ω or less to ground on its starter relay outputs after 8 failures in 10 samples. P2AF7 covers the open line, P2AF9 the short to voltage.
