2007 Chevrolet Trailblazer Airbag Control Module (OEM)

Buying an ACM can be tricky. Here's what to keep in mind:

• Check the part. Look for any signs of damage, like cracks or corrosion.
• Confirm the source. Make sure you're buying from a reputable seller.
• Ask about testing. A tested part is more likely to work correctly.
• Review the warranty. A warranty protects you if the part fails.

What makes one ACM better than another?

• Quality of components. OEM parts are made to strict standards.
• Testing procedures. Thorough testing catches problems before you install the part.
• Warranty coverage. A longer warranty gives you more peace of mind.

What do you usually get when you buy an ACM? You'll typically receive just the module itself. You may need to reuse your existing mounting hardware.

Replacing an ACM is usually a medium-difficulty job. Expect it to take 1-2 hours.

You might need these tools:

• Socket set
• Screwdrivers
• Scan tool (to clear airbag codes)

Here are the basic steps:

1. Disconnect the negative battery cable. This is very important!
2. Find the ACM. It's often under the center console or under a seat.
3. Remove the old ACM. Unplug the connectors and remove any mounting screws.
4. Install the new ACM. Plug in the connectors and secure it with the screws.
5. Reconnect the battery cable.
6. Use a scan tool to clear any airbag codes.

Important tips:

• Be careful when handling the connectors.
• Make sure the connectors are fully seated.
• Double-check all your connections before reconnecting the battery.

DIY or professional install? If you're comfortable working on cars and have a scan tool, you can probably do it yourself. If not, a professional mechanic is a good choice. Airbag systems are important for safety, so it's best to be sure the job is done right.

You have a couple of choices when buying an ACM: used OEM or new aftermarket.

• Used OEM: These are original factory parts. They've been tested and inspected. They offer great value.
• New Aftermarket: These are brand-new parts made by other companies. They're built to meet the original equipment (OE) specifications.

Used OEM parts are a good way to save money while getting a quality part. They're genuine factory parts that have been tested to ensure they work.

New aftermarket parts are another option. They're brand new and made to fit and function like the original.

When replacing the ACM, it's a good idea to check other parts of the airbag system.

• Airbag sensors: These sensors tell the ACM when to deploy the airbags.
• Clock spring: This part connects the steering wheel to the airbag system.
• Seat belt pretensioners: These tighten the seat belts in an accident.

Why check these parts? If one part of the system fails, it can sometimes damage other parts. Replacing related parts can prevent repeat failures and keep your airbag system working properly.

How long should an ACM last? Most ACMs are designed to last the life of the vehicle. That's often 10-15 years or more.

What can shorten its life?

• Water damage
• Electrical problems
• Accidents
• Extreme temperatures

How much does an ACM cost?

• Used OEM: $50 - $150
• New Aftermarket: $100 - $300

Labor costs can add to the total price. Expect to pay $100 - $200 for labor, depending on the shop.

Total job cost:

• Used OEM with labor: $150 - $350
• New Aftermarket with labor: $200 - $500

Some vehicles have known issues with their airbag systems. For the 2006-2009 Buick, Chevrolet, GMC, Isuzu, and Saab vehicles, common complaints include:

• Airbag light coming on for no apparent reason.
• False airbag deployment.
• Difficulty clearing airbag codes.

Check for any Technical Service Bulletins (TSBs) related to the airbag system on your specific vehicle. These bulletins can provide helpful information about diagnosing and repairing common problems.

After installing the new ACM, you need to make sure it's working correctly.

• Check the airbag light. It should turn off after starting the car.
• Use a scan tool. Check for any new airbag codes.
• Test the system (if possible). Some scan tools can perform diagnostic tests on the airbag system.

Listen for any unusual noises. If you hear clicking or buzzing from the ACM, it could indicate a problem. If the airbag light comes back on, or if you have any other concerns, take your car to a mechanic for further diagnosis.

Q: Will this ACM need to be programmed?
A: Sometimes, yes. Some ACMs need to be programmed to your specific vehicle. A mechanic with a scan tool can do this.

Q: How do I know if this ACM will fit my car?
A: Make sure the part is specifically listed as compatible with your year, make, and model vehicle.

Q: What if the ACM doesn't fix the problem?
A: It could be another part of the airbag system. A mechanic can help you diagnose the issue.

Q: Do I need to disconnect the battery before installing the ACM?
A: Yes! Always disconnect the negative battery cable before working on the airbag system. This prevents accidental airbag deployment.

Q: Is it safe to drive with the airbag light on?
A: It's not recommended. If the airbag light is on, your airbags may not deploy in an accident. Get it checked out by a mechanic as soon as possible.
