2014-2023 Cherokee & 2015-2017 200 Seat Memory Module: Programming and Replacement Guide

Symptoms of a Failing Seat Memory Module

When the seat memory module begins to fail, it can cause a range of frustrating electrical issues. While a complete failure is possible, you might first notice intermittent problems. Always check the simple things first, like the related fuses in the interior and under-hood fuse boxes.

• Memory Settings Won't Save: The most common symptom is the inability to save or recall a memory position. You might press the 'Set' and '1' buttons, but the module doesn't store the new position.

• Seat and Mirrors Don't Move: When you press a memory button, nothing happens. The seat and mirrors remain in their current position.
• Easy Entry/Exit Feature Stops Working: If your vehicle is equipped with this feature (where the seat moves back automatically when you turn off the car), its failure can point to a problem with the memory module.
• Seat Moves to Incorrect Positions: The module might recall the wrong position or move the seat to a random, unsaved spot.
• Clicking Sounds Without Movement: You might hear a clicking sound from under the seat when you press a memory button, which could be the module attempting to activate the motors but failing. This can also be caused by a weak or failing battery that isn't providing enough power.
• OBD-II and Diagnostic Trouble Codes (DTCs): A scan tool may reveal specific codes related to the module. A common code is B1D9B-54 (Seat Horizontal Front Stop Not Learned-Missing Calibration), which often points to a software issue that can be fixed with a dealer update. Another potential code is B210D (Battery Voltage Low), which indicates the module detected low voltage; this could be a wiring issue or a problem with the vehicle's charging system.

Known Issues, TSBs, and Recalls

While there are no direct recalls for the seat memory module itself on these specific vehicles, there are related service bulletins and recalls you should be aware of.

Jeep Cherokee (2014-2023)

• Software Updates: FCA (Fiat Chrysler Automobiles) has issued several Technical Service Bulletins (TSBs) for newer Jeep models to address software glitches in the Memory Seat Module (MSM). Symptoms like memory settings not saving or the easy-entry feature being inoperative are often resolved by reprogramming the module with the latest software at a dealership.
• Seat Mounting Recall (2019): A recall (NHTSA campaign V31) was issued for some 2019 Jeep Cherokee models because the front passenger seat mounting bolts could be loose. This is a safety issue but is unrelated to the electronic module.

Chrysler 200 (2015-2017)

• Software Updates: TSBs were also released for the Chrysler 200 to update the "Comfort Seat and Wheel Module (CSWM)" software, which can address various seat and steering wheel heating issues.
• Occupant Classification Module Recall (2015): A recall (NHTSA campaign 16V-114, Chrysler recall S09) was issued for a small number of 2015 Chrysler 200s. It involved the front passenger Occupant Classification Module (OCM), which was improperly calibrated during a service visit, potentially affecting airbag deployment. This is a separate module from the driver's seat memory module.

Programming and Replacement

This is the most critical part of replacing the seat memory module in a Jeep Cherokee or Chrysler 200.

Proxy Alignment is Required

After installing a new or used seat memory module, a procedure called a "Proxy Alignment" (or "Proxi Alignment") must be performed. This process uses a diagnostic scan tool to synchronize all the electronic control modules on the vehicle's network (the CAN bus). The Body Control Module (BCM) updates its list of installed modules, and if the new seat memory module isn't aligned, the BCM will report a mismatch, causing the odometer to flash continuously.

Who Can Program the Module?

• Dealership: A Chrysler/Jeep/Dodge dealer is the most straightforward option. They have the proprietary wiTECH scan tool and software required to perform the proxy alignment and any necessary software updates or calibrations.
• Independent Shops: Many independent repair shops that specialize in FCA vehicles will have high-end scan tools capable of performing a proxy alignment.
• Advanced DIY: For the technically savvy DIYer, tools like AlfaOBD or Appcar DiagFCA, paired with a compatible OBD2 interface like an OBDLink MX+, can perform a proxy alignment. This is an advanced procedure that requires a laptop or Android device and careful adherence to instructions. For vehicles 2018 and newer, a security gateway bypass module is also required.

Buying a Used Seat Memory Control Module

A used OEM module is an excellent, cost-effective alternative to a new dealer part, provided you take the right precautions.

1. Match the Part Number Exactly

This is the most important step. The part number is printed on a sticker on the module itself. The part numbers for this module are in a sequence: 68105045AB, 68105045AC, AD, AE, and finally AF. The last two letters indicate a revision. Generally, a newer revision (like 'AF') can replace an older one (like 'AC'), but it's always safest to match the full part number exactly. Part number 68465229AA is a later replacement for the 68105045xx series.

2. Inspect for Physical Damage

Since the module is located under the driver's seat, it's vulnerable to damage from spills. When you receive the part, inspect it carefully:

• Check for Corrosion: Look at the connector pins. They should be clean and shiny. Any green or white crusty residue is a sign of water damage, and the module should be returned.
• Examine the Case: Check for cracks or signs that the case has been pried open.
• Listen for Rattles: Gently shake the module. There should be no rattling sounds, which could indicate broken internal components.

3. Buy From a Reputable Seller

Purchase from a seller that offers a warranty and a clear return policy. This gives you protection in case the part is dead on arrival or has hidden damage.

Cost Comparison

Prices can vary based on your location and the specific part number. Here are some typical cost ranges:
