What P2AF6 means
P2AF6 is the reverse fault on relay C: commanded to switch, the relay does not change state. Stellantis names it Starter Relay 3 Stuck Off, on some Wagoneers Dual Starter Relay Stuck. During an auto-start the PCM energises the relay to split the batteries; if it then finds hardly any gap between the auxiliary and the main battery voltages, the relay evidently stayed put, so P2AF6 is stored with MIL and stop-start shuts down. Bulletin 08-138-23 traced it on 2022–2023 Wagoneers to connector D3157A at the power distribution centre that had not clicked fully into place. The RAM 1500 2025 with the 3.0 L Hurricane and stop-start and later Wagoneers got PCM software that lets the permanent code clear. A drained auxiliary battery can also produce false fails.
P2AF6 at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyEasy, DIY possible
- Typical labor0.3 to 1.5 hours
- Clears after repairAfter a drive cycle
Symptoms of P2AF6
- Check engine light on
- Stop-start disabled
- Occasional failure to restart after an auto-stop
Common causes of P2AF6
- Most likelyPower distribution centre connector not fully seated
- PossiblePCM software needing an update
- PossibleDepleted auxiliary battery causing a false fail
- Less likelyPower control relay not switching
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2AF6 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. |
| F6 | The exact fault in that area. |
What to do next
- Note P2AF6 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 P2AF6
What does P2AF6 mean?
P2AF6 means "Starter Relay C Stuck Off". P2AF6 is the reverse fault on relay C: commanded to switch, the relay does not change state. It is a generic code, so it means the same on every make.
Is it safe to drive with P2AF6?
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 P2AF6 fail an emissions test?
P2AF6 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 P2AF6 to fix?
Difficulty: easy. A typical repair takes 0.3 to 1.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P2AF6 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.
