What P2AF8 means
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.
P2AF8 at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 3 hours
- Clears after repairAfter a drive cycle
Symptoms of P2AF8
- No start or no crank
- Several unrelated electrical faults at the same time
- Stop-start unavailable
Common causes of P2AF8
- Most likelySpread or bent terminals in the power distribution centre connector
- PossibleControl wire shorted to ground
- Less likelyShorted relay coil
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2AF8 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| A | Area: hybrid propulsion. |
| F8 | The exact fault in that area. |
What to do next
- Note P2AF8 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2AF8
What does P2AF8 mean?
P2AF8 means "Starter Relay D Control Circuit Low". P2AF8 is logged when the control line of starter relay D shows a short to ground. It is a generic code, so it means the same on every make.
Is it safe to drive with P2AF8?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P2AF8 fail an emissions test?
P2AF8 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P2AF8 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P2AF8 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
