Owners of the 2024 Jeep Wrangler (MY 24 JL) may experience diagnostic trouble codes (DTCs) P2AF5 or P2AF6, indicating potential issues with the FUSE BLOCK - PWR DISTRIBUTION system, part number 68574989AS. These codes, however, are often false diagnostic failures, leading to unnecessary part replacements. This issue is documented under internal reference 9100651, dated August 12, 2025.

- DTC P2AF6: This code also indicates a false failure related to PCR, DBSM, or PDC diagnostics, but for an 'open diagnostics' condition.
These codes suggest a problem with the FUSE BLOCK - PWR DISTRIBUTION system, but the underlying cause is often not a faulty component itself.
Diagnosis and Trigger Conditions
The manufacturer has identified that these false diagnostic failures, including DTC P2AF5 and DTC P2AF6, are frequently triggered by a depleted auxiliary battery condition.
