2021 Jeep Compass P0513 No Start After BCM Replacement TSB

Owners of the 2021 Jeep Compass may encounter a significant issue following the replacement and programming of their vehicle's Body Control Module (BCM). This technical service bulletin, identified as S2508000085, addresses a specific problem where an incorrectly installed BCM can lead to a 'no crank no start' condition, accompanied by diagnostic trouble code (DTC) P0513.

This bulletin, released in October 2025, highlights the critical importance of using the correct BCM part number to ensure proper vehicle operation and prevent starting issues in the 2021 Jeep Compass. The problem arises when BCM part number 68490749AB, intended for M7 PHEV vehicles, is mistakenly installed in an MP gas engine model.

Symptoms

If your 2021 Jeep Compass experiences a 'no crank no start' condition after a BCM replacement, it's a key indicator of this specific problem. This means the engine will not turn over or attempt to start when the ignition is engaged. Technicians scanning the vehicle's systems will likely find the diagnostic trouble code P0513 stored in the Powertrain Control Module (PCM). The specific message associated with this is "P0513 - Invalid SKIM Key Active In PCM".

Fault Codes / DTCs

The primary diagnostic trouble code associated with this issue is:

Code	Description	Module
P0513	Invalid SKIM Key Active In PCM	PCM

This code indicates that the Sentry Key Immobilizer Module (SKIM) key is not being correctly recognized by the Powertrain Control Module, preventing the engine from starting and causing the "no crank no start" condition.

Diagnosis and Trigger Conditions

The root cause of the 'Jeep Compass P0513 no start' condition is the installation of an incorrect Body Control Module (BCM) with part number 68490749AB. While this BCM may physically connect to the vehicle, it is specifically designed for M7 PHEV (Plug-in Hybrid Electric Vehicle) models only. It was erroneously listed as a suitable replacement for MP gas engine vehicles in the STAR Parts service listing.

When BCM part number 68490749AB is installed in an MP gas engine vehicle, its hardware and software are incompatible with the vehicle's systems. This incompatibility leads to the Powertrain Control Module (PCM) detecting an "Invalid SKIM Key Active In PCM," resulting in the P0513 code and the inability to start the engine.

Repair Procedure Summary

The STAR Parts service listing, which previously contained the incorrect BCM part number, has since been corrected. To resolve the 'Jeep Compass P0513 no start' issue, the incorrect BCM (part number 68490749AB) must be replaced with the correct one.

As of the authoring of this bulletin S2508000085, the latest correct replacement part number available for ordering is 68411149AG. Technicians should always confirm the correct and latest released BCM by using the vehicle's VIN and reviewing the supersedence listing within the STAR Parts system. If the part is urgently needed, it can be ordered using Vehicle Off Road (VOR) status for expedited delivery.

Required Parts

• Incorrect BCM (to be replaced): 68490749AB (intended for M7 PHEV vehicles ONLY)
• Correct BCM (replacement part): 68411149AG (latest replacement part number as of bulletin authoring)
