2019-2023 Jeep Cherokee Engine Control Module Bracket: A Guide to Inspection and Replacement
This guide covers the essential role of the ECM support bracket in your 2019-2023 Jeep Cherokee, how to spot damage, and why securing your engine's computer is critical.
- The primary symptom of a bad bracket is a rattling noise or visible physical damage; engine performance issues are a rare, secondary effect.
- This part is not a common failure item; damage is most often caused by a collision or severe corrosion.
- A used OEM bracket is a great value, but inspect it carefully for cracks and bends before purchasing.
- Replacement is a simple DIY job that requires no special tools or computer reprogramming.
Symptoms of a Damaged or Loose ECM Bracket
The ECM bracket itself has no electronics; it is a structural metal part. Therefore, its failure symptoms are physical and auditory, or they are the secondary result of the ECM being damaged. Most bracket failures occur due to collision damage or corrosion.
- Rattling or Buzzing Noises: The most common symptom of a loose or broken ECM bracket is a metallic rattling or buzzing sound coming from the engine bay. This noise may be most noticeable at idle or at specific engine speeds where vibrations are most pronounced.
- Visible Damage: A visual inspection is the best diagnostic tool. Look for cracks, especially around the mounting points and bends in the metal. The bracket may also be bent or deformed from an accident. Severe rust and corrosion can weaken the bracket, leading to potential failure.
- Intermittent Electrical Issues (Secondary Symptom): In severe cases, if the ECM is no longer held securely, constant vibration and movement can stress the electrical connectors plugged into the module. This could potentially lead to intermittent engine problems like stalling, misfiring, or a Check Engine Light. These symptoms are more commonly caused by other issues, but a loose ECM should be considered as a possible contributing factor.
Buying a Used Engine Control Module Support Bracket
For a simple structural part like an ECM bracket, a used OEM component is an excellent value. Since there are no known aftermarket options available, your choice is between a new OEM part and a recycled OEM part.
Pro Tip: This part is often left on the Engine Control Module when sold by recyclers. If you are buying a used ECM, confirm if it includes the bracket, as you may not need to purchase it separately.
When inspecting a used bracket, check for these key issues:
- No Cracks or Fractures: Carefully examine the entire bracket, paying close attention to the welds, corners, and bolt holes. Stress from vibration or an impact can cause hairline cracks that compromise its strength.
- Check for Straightness: Place the bracket on a flat surface to ensure it isn't warped or bent. A bracket that was damaged in a collision may look fine at first glance but may not align properly with the mounting points on your vehicle.
- Minimal Corrosion: Surface rust is usually not a major concern and can be cleaned off. However, you should reject any bracket with deep, flaking rust or corrosion that has eaten away at the metal, as its structural integrity is compromised.
- Verify the Part Number: Always match the OEM part number to ensure compatibility. The primary verified part number for this bracket is 68328870AA.
Known Issues, TSBs, and Recalls
As of mid-2026, there are no specific recalls or widespread Technical Service Bulletins (TSBs) related to the Engine Control Module support bracket for the 2019-2023 Jeep Cherokee. The part appears to be robust with no common failure pattern outside of physical damage or corrosion.
Recall Notice (Unrelated): Many 2019-2023 Jeep Cherokee models were recalled for a potentially failing Power Transfer Unit (PTU) that could cause a loss of power (NHTSA Recall 26V290). This is a serious drivetrain issue but is not related to the Engine Control Module or its mounting bracket.
Installation and Replacement
Replacing the ECM bracket is a straightforward job suitable for a DIY mechanic with basic tools. The ECM is located in the engine bay, typically near the battery and main fuse box.
General Steps:
- Disconnect the Battery: Always disconnect the negative battery terminal before working on any part of the vehicle's electrical system.
- Unplug the ECM: Carefully release the locking tabs on the large electrical connectors and pull them straight out from the ECM.
- Unbolt the Bracket: Remove the bolts securing the bracket (with the ECM still attached) to the vehicle's chassis.
- Swap the ECM: Once the assembly is out, unbolt the ECM from the old bracket and mount it to the new one.
- Reinstall: Bolt the new bracket and ECM assembly back into the vehicle, reconnect the electrical connectors, and finally, reconnect the battery.
Pro Tip: You do not need to reprogram the computer. Since you are only replacing the bracket and reusing your original ECM, no software changes are necessary.
Cost Comparison
The cost for an ECM support bracket is relatively low, making a new OEM part an affordable option. Aftermarket versions of this specific bracket are not commonly available.

| New OEM | $22 - $35 |
| New Aftermarket | Not Available |
| Used OEM | $15 - $25 |
| Shop Labor | $50 - $100 |
Frequently Asked Questions (FAQ)
Can a broken ECM bracket cause my Jeep to not start?
It is highly unlikely. A broken bracket itself cannot prevent the engine from starting. However, in a very extreme and rare case, if the ECM were allowed to vibrate violently for a long period, it could damage the internal circuit board or the connector pins, leading to a no-start condition. The more immediate symptom would be noise or visible damage.
Where is the ECM bracket located on a 2019-2023 Jeep Cherokee?
The Engine Control Module and its bracket are located in the engine compartment. On most modern vehicles, including the Cherokee, you can typically find it mounted to the firewall or inner fender, often near the battery or the under-hood fuse box.
Do I need to reprogram my Jeep after replacing the ECM bracket?
No. The bracket is just a piece of metal. As long as you are reinstalling your original Engine Control Module, no programming or software updates are required. The vehicle will function exactly as it did before.
Is this bracket the same for all 2019-2023 Jeep Cherokee engines?
Part number 68328870AA is listed as fitting the 2.4L I4, 3.2L V6, and 2.0L Turbo engines, covering the vast majority of Cherokees from this period. However, it is always best to verify fitment for your specific vehicle using your VIN with an OEM parts supplier.
