2021-2024 Jeep Compass/Renegade BCM Replacement Guidelines

This Technical Service Bulletin (TSB) 08-258-24, issued on December 21, 2024, provides essential guidelines for technicians performing a Body Control Module (BCM) replacement on specific exFCA vehicles within the Enlarged Europe (EE) market. The document clarifies the procedures for ordering and coding new BCMs, especially for models equipped with the Integrated Body Computer 2XD.

For owners of affected vehicles, understanding the details of a Jeep Compass BCM replacement or Jeep Renegade BCM replacement can help ensure proper service. This TSB is crucial for technicians to correctly replace the BCM and ensure all vehicle functions, including passive entry and keyless start, operate as intended.

Overview of BCM Replacement Guidelines

When a BCM needs to be replaced, the general procedure involves following the instructions in the service manual (eLearn - Service Library). Most BCMs are supplied pre-coded with the Vehicle Identification Number (VIN), PROXI configuration, and key codes, making them ready for use upon installation. In these cases, no further action is typically required unless a Field Action (such as SR, ER, CSN, RSU) or another TSB specifies a software update.

However, certain vehicle configurations require additional coding using the wiTECH diagnostic tool after the BCM replacement. This is a critical step to ensure the new BCM is correctly integrated with the vehicle's systems.

Vehicles Requiring wiTECH Coding After BCM Replacement

The following table details specific vehicle models and configurations where the BCM will be supplied without VIN, PROXI, and key coding. For these vehicles, the BCM must be coded using wiTECH after replacement. Technicians should always refer to the service manual for the most accurate instructions.

Model Code (eSiGi)	Brand	Model Description	Version	MY	Equipment
290-291	FIAT	Ducato	MCA & NG24	MY21 Onwards	All
949-952	ALFA ROMEO	Giulia & Stelvio	All	All	All
587/609/687	JEEP	Renegade	All	All	With FOBIK keys, without IBCM
334	FIAT	500X	All	All	With FOBIK keys, without IBCM
356-357	FIAT	Tipo MCA	HB-SW	2022 Onwards	With FOBIK keys

For the vehicles listed above, wiTECH will prompt a specific procedure called "BCM Substitution" within the "Miscellaneous Functions" menu of the BCM. This function guides the technician through the necessary coding steps.

Integrated Body Computer Module (iBCM) Specifics

For vehicles equipped with an Integrated Body Computer Module (iBCM), which implements both Radio Frequency Hub Module (RFHM) and Secure Gateway Module (SGW) functions, additional considerations apply. The iBCM can be identified by checking specific sales codes, such as OPT 2XD for FLAPH vehicles or 2PL sales code for CJDR vehicles.

While iBCMs are typically delivered pre-coded with VIN and PROXI, they require further operations to function correctly after replacement. These include:

• Security Gateway Module (SGW) update: Ensuring the latest security protocols are in place.
• BCM update: Only if suggested by the wiTECH diagnostic system.
• FOBIK key learning: This involves a "Disable Fobik" procedure found in the Miscellaneous Functions menu of the BCM. FOBIK refers to hands-free remote control, passive entry, or keyless go functions, identifiable by GXP/GX4 OPT codes for FLAPH vehicles or GXD/GX4 sales codes for CJDR vehicles.

Notably, if available in the BCM's Miscellaneous Functions menu, a "BCM Substitution" function can be run. This function groups and streamlines all the necessary procedures for a comprehensive Jeep Compass BCM replacement or other applicable models.

Important Warnings

This bulletin is provided solely as technical information and does not authorize repairs. It is intended for informational purposes only, guiding technicians through the correct procedures for BCM replacement. Owners should be aware that this document is for dealer reference and does not constitute an authorization for repair or a recall notice.

Owner Action

If you believe your vehicle requires a BCM replacement or if you are experiencing issues related to your BCM, it is essential to consult an authorized dealership. They have access to the specific service manuals, diagnostic tools like wiTECH, and the latest software updates required to correctly perform a BCM replacement and coding according to TSB 08-258-24.
