P2AF6: Starter Relay C Stuck Off

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.

Symptoms

• Check engine light on
• Stop-start disabled
• Occasional failure to restart after an auto-stop

Most likely causes

• Power distribution centre connector not fully seated
• PCM software needing an update
• Depleted auxiliary battery causing a false fail
• Power control relay not switching

What to check, in order

Start with the simplest. You can tick off each step.

1. Check the battery voltage
2. Use the scanner to command the movement and compare the actual position with the requested one.
3. Try another key, if you have one
4. Check the fuses and the starter relay
5. Check the wiring and the signal to the starter motor

Good to know

• Repair difficulty: easy

What each character of P2AF6 means

• P: Powertrain: engine and transmission
• 2: Generic code: same on every make
• A: Hybrid or air and fuel
• F6: Specific fault in that system

Frequently asked questions

Can I keep driving with code P2AF6?

If it starts normally you can keep driving, but avoid stopping anywhere you could not get help, because it might not restart.

What causes code P2AF6?

The most common causes are: power distribution centre connector not fully seated; pCM software needing an update; depleted auxiliary battery causing a false fail.
