How the car detects it
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.
