2019-2023 Jeep Cherokee ECM Bracket: Fitment Guide for the 2.4L & 3.2L Engines
This guide details the specific Engine Control Module (ECM) bracket for the 2019-2023 Jeep Cherokee, highlighting the critical engine compatibility you must verify before buying.
- This bracket (68328870AA) ONLY fits 2019-2023 Jeep Cherokees with the 2.4L or 3.2L engine; it does NOT fit the 2.0L Turbo.
- Failure is always physical (cracks, bends from impact, corrosion); symptoms are secondary, like rattling or electrical issues from a loose ECM.
- When buying used, inspect for cracks and heavy rust, but a good condition used OEM part is a reliable, cost-effective option.
- No ECM reprogramming is needed when replacing only the bracket.
Critical Compatibility Warning: Engine-Specific Fitment
Warning: This Engine Control Module bracket, OEM part number 68328870AA, is only compatible with 2019-2023 Jeep Cherokee models equipped with the 2.4L I4 or 3.2L V6 engine. It will NOT fit models equipped with the 2.0L Turbo engine. The engine bay layout and ECM placement are different on 2.0L Turbo models, requiring a different bracket. Always verify the engine in the vehicle before purchasing this part.
Symptoms of a Failing ECM Bracket
As a simple piece of metal, the bracket itself does not have electronic symptoms of failure. Instead, failure is physical, typically due to a collision, corrosion, or stripped mounting bolts. A broken or loose bracket will lead to secondary problems:
- Rattling or Clunking Noises: The most common symptom is a noticeable rattling sound coming from the engine bay, especially over bumps or during engine vibration. This is the sound of the unsecured ECM moving around in its mount.
- Intermittent Electrical Problems: If the ECM is allowed to vibrate excessively, it can put stress on its large electrical connectors. This can cause intermittent issues like engine stalling, hesitation, or a dashboard lit up with random warning lights as connections are momentarily lost.
- Visible Damage: In cases of front-end or side impact, the bracket may be visibly bent, cracked, or broken. Corrosion around the mounting points can also weaken the bracket, causing it to fail under the stress of normal driving.
Buying a Used Engine Control Module Bracket
For a simple structural part like this, a used OEM bracket is an excellent value. Since aftermarket versions are not commonly available, your main choices are new OEM or used OEM. Here’s what to look for when buying used:
- Inspect for Physical Damage: Carefully check the entire bracket for any signs of stress. Look for hairline cracks, especially around the mounting holes and corners. Ensure it is not bent or warped, as this will prevent it from aligning correctly with the mounting points on the vehicle's body and the ECM itself.
- Check for Corrosion: Pay close attention to the bolt holes and any welded joints. Surface rust is often cosmetic, but heavy, flaking rust can compromise the bracket's structural integrity. A part from a dry, southern climate is always preferable.
- Verify All Mounting Points are Intact: Make sure none of the tabs or holes are broken off or stripped. The bracket must be able to hold the ECM securely with all intended factory hardware.
- Why Used OEM is a Smart Choice: A used OEM bracket that passes a physical inspection is functionally identical to a new one. It is made from the same gauge steel and to the same factory specifications, ensuring a perfect fit. This makes it a reliable and cost-effective alternative to a more expensive new part from a dealer.
Related Technical Service Bulletins (TSBs) and Recalls
While there are no recalls for the bracket itself, there are important software updates and recalls for the ECM it holds. Before assuming your ECM is bad, check for these issues.
- TSB 18-077-22 for PCM Reflash: Some 2019 Cherokee models with the 3.2L V6 may experience a check engine light with various codes, including P0456 (EVAP leak) or P06DD (oil pressure circuit). This TSB instructs dealers to reprogram (or "flash") the Powertrain Control Module with updated software. This is a much cheaper fix than replacing the entire ECM and should be investigated first if you have these symptoms.
- Recall U87 - PCM Voltage Regulator: A recall was issued for some 2018-2019 Jeep Cherokees because the Powertrain Control Module (PCM) might have a faulty voltage regulator chip. This defect could cause the engine to stall or fail to start, increasing the risk of a crash. A dealer can check your VIN to see if your vehicle was affected and if the recall work was completed.
- Recall 40D - Power Transfer Unit (PTU): A recent recall (May 2026) affects many 2019-2023 Cherokees for a failing PTU, which can cause a loss of power or a vehicle rollaway. While unrelated to the ECM, it is a significant issue for these vehicles that owners should be aware of.
Installation and Replacement
Replacing the ECM bracket is a straightforward process that is feasible for a DIY mechanic with basic tools. The ECM is typically located in the engine bay, near the battery or firewall.
- Disconnect the Battery: Always disconnect the negative battery terminal before working on any part of the vehicle's electrical system.
- Unplug the ECM: Release the locking tabs on the large wiring harnesses connected to the ECM and carefully pull them straight out. These connectors can be delicate, so do not use excessive force.
- Unbolt the ECM from the Bracket: Remove the bolts (typically three or four) that secure the ECM to the bracket.
- Unbolt the Bracket from the Vehicle: Remove the bolts that secure the bracket to the vehicle's chassis or inner fender well.
- Installation: Installation is the reverse of removal. Mount the new bracket, attach the ECM to it, plug in the wiring harnesses, and finally, reconnect the battery.
Pro Tip: You do not need to reprogram or flash the ECM when only replacing the bracket. Since the original ECM is being reused, all of its programming and vehicle-specific data remain intact.

Frequently Asked Questions (FAQ)
Why won't this bracket fit my 2020 Cherokee with the 2.0L Turbo engine?
The 2.0L Turbo engine has a different physical layout in the engine bay, which means the Engine Control Module is mounted in a different location or orientation. This requires a unique bracket designed specifically for that powertrain. Part number 68328870AA is only for the 2.4L and 3.2L models.
Can a broken ECM bracket cause my Jeep to not start?
Indirectly, yes. While the bracket itself has no electrical function, if it breaks and allows the ECM to move around, it can damage the wiring connectors or the ECM's internal circuit board over time. This damage can eventually lead to a no-start condition or intermittent stalling.
Is this the same as a radiator support bracket?
No. Despite some confusing online listings, this part is exclusively for mounting the Engine Control Module. It is not part of the radiator support structure, which is located at the front of the vehicle.
Do I need to take my Jeep to the dealer after replacing just the bracket?
No. As long as you are reusing your original Engine Control Module, no programming or dealer visit is required. The bracket is a simple mounting component, and replacing it does not affect the vehicle's software or security systems.
