The 2026 bulletin identifies clutch-interlock-switch terminal corrosion as a cause of P083F on the specified manual-transmission Wrangler.

Documented application

FCA 08-022-26 concerns 2025 Wrangler JL with the six-speed manual DEM transmission in North America. Its VIN-eligibility wording needs current dealer confirmation.

The code alone does not identify a failed part or establish that a vehicle is safe to drive. Confirm the vehicle, reporting module and applicable service procedure.

A correlation fault with a documented connector issue

The 2026 bulletin identifies clutch-interlock-switch terminal corrosion as a cause of P083F on the specified manual-transmission Wrangler. Reported effects include a no-start condition and disabled stop/start. The code compares clutch-switch information; it does not establish that the clutch friction assembly is worn or that the transmission needs replacement.

Replacement alone omits a required step

The revised repair replaces the clutch interlock switch, addresses corrosion at its electrical connector and then performs a clutch-pedal-position learn through the diagnostic system. That learning step matters when a new switch has already been fitted but the correlation complaint continues. The prior revision’s inspection steps were removed, so using an older abbreviated procedure may not reproduce the current document’s repair.

Resolve applicability before acting

The diagnosis section contains mixed wording: it mentions symptomatic vehicles outside the VIN list, then states that the bulletin applies only to listed VINs. This article does not choose the broader interpretation. Have the servicing dealer confirm current eligibility and the applicable procedure for the actual vehicle. Other faults or symptoms must still be addressed before applying this case. A useful completion record identifies the switch and connector work, confirms the learn procedure, and records the resulting start and fault behavior. Never bypass the clutch-start interlock to work around P083F; that would remove a safety function rather than diagnose the correlation problem.
