Your car’s control module is one of the most important components in ensuring a smooth and efficient ride. Whether it’s an Engine Control Module (ECM), Powertrain Control Module (PCM), or Transmission Control Module (TCM), these electronic units play a crucial role in regulating engine performance, fuel efficiency, and transmission behavior.
At Clifford Auto Parts, we specialize in providing OEM control modules that guarantee compatibility, reliability, and long-term performance. But how do you know when it’s time to replace your control module? Let’s break it down!
✅ What Is a Control Module and What Does It Do?
A control module is an onboard computer that processes data from various sensors in your car and makes real-time adjustments to optimize performance. Some of the most common control modules include:
✔️ Engine Control Module (ECM) – Controls ignition timing, fuel injection, and emissions.
✔️ Powertrain Control Module (PCM) – Manages both engine and transmission functions.
✔️ Transmission Control Module (TCM) – Regulates gear shifting and transmission efficiency.
✔️ Body Control Module (BCM) – Handles electrical functions such as lighting, locks, and windows.
When these modules start to fail, your car may experience serious performance issues that could lead to costly repairs.
✅ Signs of a Failing Control Module
If your control module is going bad, your car will usually give you warning signs. Here are the top indicators that it may be time for a replacement:
🚨 Check Engine Light Stays On
If your Check Engine Light won’t turn off even after repairs, it could be due to a failing ECM or PCM.
🚨 Poor Fuel Efficiency
A malfunctioning control module may send incorrect signals, leading to excess fuel consumption and reduced mileage.
🚨 Difficulty Starting the Car
If your car struggles to start, the ECM might not be properly managing the fuel and ignition system.
🚨 Transmission Issues
A faulty PCM or TCM can cause hard shifting, gear slipping, or delayed acceleration.
🚨 Engine Stalling or Misfiring
A failing ECM can result in irregular combustion cycles, leading to stalling, misfires, and sluggish performance.
🚨 Electrical Malfunctions
The BCM controls many electronic functions, so if your power windows, locks, or headlights start acting up, it may be time for a replacement.
✅ What Causes Control Modules to Fail?
Several factors can lead to a control module failure, including:
🔥 Water or Moisture Damage – Exposure to moisture can corrode internal circuits.
⚡ Voltage Surges – A faulty alternator or battery can overload the control module.
🔧 Worn-Out Components – Over time, electronic components degrade, leading to failure.
💥 Physical Damage – Accidents or engine overheating can cause module failure.
If you’re experiencing any of these issues, replacing your control module can prevent further damage and restore your vehicle’s performance.
✅ Why Choose an OEM Control Module Over Aftermarket?
When replacing a control module, you have two options: OEM (Original Equipment Manufacturer) or Aftermarket. Here’s why OEM control modules are the best choice:
✔️ Guaranteed Compatibility – Designed specifically for your vehicle’s make and model.
✔️ Pre-Programmed for Plug-and-Play Use – No extra programming needed.
✔️ Factory-Tested for Reliability – OEM parts undergo rigorous quality checks.
✔️ Maintains Vehicle Warranty – Aftermarket parts may void manufacturer warranties.
✔️ Longer Lifespan – OEM modules are built to last, unlike some aftermarket options.

On Feb. 18, 2025, the automakers released a legislative proposal related to automotive right to repair; the views cited in this proposal represent a small fraction of the repair market and are not representative of the broader automotive aftermarket, MEMA said. The industry does appreciate automakers’ acknowledgment of the need for federal legislation to protect consumer choice in vehicle repair and looks forward to congressional consideration of the REPAIR Act.
Auto Care Association President and CEO Bill Hanvey and MEMA Aftermarket Suppliers President Paul McCarthy released the following statement:
“We’re pleased to see trade groups representing automakers finally admit what we’ve long known: congressional action is needed to ensure independent shops and aftermarket parts manufacturers can continue to offer Americans quality, affordable choices for vehicle repairs.
“That said, this latest proposal appears to be a tactic to delay and defeat pro-consumer right to repair legislation at every level. The bipartisan Right to Equitable and Professional Auto Industry Repair Act (REPAIR Act) is a straightforward approach to ensure safe and secure access to vehicle repair and maintenance data.
“The REPAIR Act, led by Congressman Neal Dunn, is the solution. Protection of consumer and fleet-owner choice ensured access to critical repair data, an established federal enforcement mechanism, and the prevention of repair monopolies is accomplished through the REPAIR Act. Without it, the aftermarket will lose the ability to not only innovate but continue to offer consumers options to keep their vehicles on the road.

Judge Denise Casper dismissed the entirety of the Alliance for Automotive Innovation’s suit challenging the 2020 Massachusetts Data Access Law. The automakers’ bid to block the Massachusetts
link hidden, please login to viewlaw has failed and the law remains in effect. The judge’s written decision is still under seal but should be made available to the public soon. “Today’s ruling is a significant victory for the people of Massachusetts—and all Americans,” said Bill Hanvey, president and CEO, Auto Care Association. “This decision by Judge Casper ensures that car owners have the right to access their vehicle’s repair and diagnostic data, empowering them to make informed choices about maintenance and repairs. It levels the playing field, allowing independent repair shops to compete fairly, which in turn drives down costs for consumers. As car owners, we all deserve the freedom to control and manage the data that’s generated by our own vehicles. This ruling is a crucial step toward fostering greater transparency, affordability, and innovation in the automotive industry for the benefit of all Americans.”

Bill Long, president & CEO,
link hidden, please login to view, The Vehicle Suppliers Association, issued this statement regarding the implementation of China tariffs to its membership. Dear MEMA Members,
On February 1, 2025, President Trump signed an
link hidden, please login to view which imposed new tariffs on the majority of items coming from China into the U.S. These new tariffs are being implemented under the International Emergency Economic Powers Act (IEEPA). The IEEPA tariffs, set at 10%, went into effect at 12:01 am ET on February 4, 2025. There is currently no date by which the tariffs will sunset. Further, the 10% tariffs articulated in this Executive Order will be imposed on top of any prior and existing “duties, fees, exactions, or charges applicable to such imported articles.” China subsequently announced retaliatory tariffs of between 10-15% on certain U.S. goods and further imposed export controls on five critical minerals.
Additional Details:
Goods in Transit: U.S. Customs and Border Protection (CBP) issued a
link hidden, please login to view on February 5, 2025 and link hidden, please login to view via the Cargo System Messaging Service which provide more information on the items covered by the new tariffs. Consistent with the language included in the Executive Order, CBP noted that items that are onboard a vessel before 12:01 am EST on February 1, 2025 are exempt from the newly imposed Chinese tariffs of 10% as long as they are entered for consumption (or withdrawn from warehouse for consumption) before 12:01 am EST on March 7, 2025.
However, products of China that are entered for consumption beginning February 4, 2025 would be subject to the new tariffs. Therefore, if there is a product of China that is placed on the vessel between February 1, 2025 and February 3, 2025, but it is not entered until February 4, 2025 or later, then it would still be subject to the tariffs.
CBP further issued guidance via its Cargo Systems Messaging Service on how companies can certify eligibility for this provision. Importers will need to use secondary HTS 9903.01.23 if they are eligible for this “on the water” exception. The use of HTS 9903.01.23 will only be available for those imports within those time-bound requirements.
Goods Covered by the Executive Order: The CBP notice covers the majority of goods coming from China into the U.S. There are very limited exceptions for donations (i.e., food, clothing, medicine used to relieve human suffering) and informational materials (e.g., publications, films, posters). In addition, an importer can make use of the Chapter 98 duty saving or reduction provisions (e.g., U.S. goods returned, goods exported for repair/alteration and returned). See below.
Excluded from the IEEPA Tariffs:
9903.01.21: Articles the product of China and Hong Kong that are donations, by persons subject to the jurisdiction of the United States, of articles, such as food, clothing, and medicine, intended to be used to relieve human suffering.
9903.01.22: Articles the product of China and Hong Kong that are informational materials, including but not limited to, publications, films, posters, phonograph records, photographs, microfilms, microfiche, tapes, compact disks, CD ROMs, artworks, and news wire feeds.
CHAPTER 98: The additional duties imposed by heading 9903.01.20 shall not apply to goods for which entry is properly claimed under a provision of chapter 98 of the tariff schedule pursuant to applicable regulations of CBP, and whenever CBP agrees that entry under such a provision is appropriate, except for goods entered under heading 9802.00.80; and subheadings 9802.00.40, 9802.00.50, and 9802.00.60. For subheadings 9802.00.40, 9802.00.50, and 9802.00.60, the additional duties apply to the value of repairs, alterations, or processing performed (in China and Hong Kong), as described in the applicable subheading. For heading 9802.00.80, the additional duties apply to the value of the article assembled abroad (in China and Hong Kong), less the cost or value of such products of the United States, as described.
Drawback: The Executive Order states that drawback will not be available for items covered by the IEEPA tariffs.
De Minimis: The Executive Order revoked duty-free “de minimis” treatment for goods coming into the U.S. from China that are subject to the order. According to CBP: “De minimis provides admission of articles free of duty and of any tax imposed on or by reason of importation, but the aggregate fair retail value in the country of shipment of articles imported by one person on one day and exempted from the payment of duty shall not exceed $800.” For more information, see the CBP Guidance on De Minimis Shipments from China:
link hidden, please login to view NOTE: De Minimis Update on 2/7/2025: The White House issued an Executive Order which announced the suspension of the afore-mentioned revocation on de minimis treatment for goods coming from China. MEMA is still analyzing the new order but it indicates that the revocation would return once “adequate systems are in place to fully and expediently process and collect tariff revenue applicable.”
Source:
link hidden, please login to view CBP is expected to issue an updated guidance document to help inform the trade community of the details concerning this change. MEMA will share this information as soon as it becomes available.
Free Trade Zones (FTZ): Beginning February 4, goods subject to these IEEPA tariffs must be admitted in a zone as “privileged foreign status” (with limited exceptions for goods eligible for “domestic status”). When withdrawn from the zone and entered for consumption, the goods will be subject to the IEEPA tariffs (and other applicable duties) related to the classification under the applicable HTSUS subheading in effect at the time of admission.
Exclusions: At this time, there is no language in the Executive Order concerning an exclusion process.
Escalation: The Executive Order includes language stating that the U.S. may escalate these actions if China takes steps to retaliate against U.S. exports and goods.
MEMA will continue to update member companies on any new developments regarding the tariffs. As new details may evolve, we will promptly notify members of any changes as soon as more information becomes available.
