2024-2026 Jeep False DTCs P2AF5 P2AF6 Relay Module Issue

Frequently Asked Questions

What are DTC P2AF5 and P2AF6?

DTC P2AF5 and P2AF6 are diagnostic trouble codes that, in 2024-2026 Jeep Wrangler, Gladiator, and Compass vehicles, can be falsely triggered. They are associated with diagnostic issues related to the relay module (Part Number: 56029766AS) and other electrical components like the Power Control Relay (PCR), Drive Battery Sensor Module (DBSM), and Power Distribution Centers (PDCs).

Why are these DTCs considered 'false fails'?

These diagnostic trouble codes are considered 'false fails' because the vehicle's control systems are not robust enough to accurately interpret conditions when the auxiliary battery is depleted. This can lead the system to incorrectly report faults with components like the PCR, DBSM, and PDCs, even when these parts are functioning correctly. This can result in a Jeep Wrangler false DTC P2AF5 appearing without an actual component failure.

What should I do if my Jeep displays DTC P2AF5 or P2AF6?

If your 2024-2026 Jeep Wrangler, Gladiator, or Compass displays DTC P2AF5 or P2AF6, it is important to inform your service center about Manufacturer Communication 9100649 and Service Operation Letter (SOL) S2508000031. This will ensure that technicians follow the correct diagnostic procedures to avoid unnecessary part replacements, as the issue may stem from a depleted auxiliary battery rather than a faulty component.

Can a depleted auxiliary battery cause these false codes?

Yes, a depleted auxiliary battery condition is explicitly identified as a contributing factor to these false diagnostic trouble codes. The vehicle's current control systems are not robust against this condition, meaning a low auxiliary battery can trigger the P2AF5 or P2AF6 DTCs, leading to misdiagnosis of other electrical components.
