Buying a CCM can be tricky. Here's what to look for:

• Check the part's condition. Look for any signs of damage or corrosion.
• Make sure it's the right part. Even if it looks the same, it might not work with your car.
• Ask about a warranty. A warranty protects you if the part fails soon after you install it.

What makes a good CCM?

• For used parts, look for ones that have been tested. This means they've been checked to make sure they work.
• For new aftermarket parts, choose a reputable brand. Some brands are known for better quality.

What's usually included with the part? Typically, you'll just get the CCM itself. You might need to reuse your old mounting hardware.

Replacing a CCM can be easy or hard, depending on your skills.

• Difficulty level: Medium
• Estimated time: 1-2 hours

Do you need special tools? Maybe. You'll need:

• Socket set
• Wrench set
• Scan tool (to clear codes)

Here are some important steps:

1. Disconnect the battery. This prevents electrical shocks.
2. Locate the CCM. It's usually under the dash or in the engine compartment.
3. Unplug the wiring harness. Be careful not to damage the connectors.
4. Remove the old CCM.
5. Install the new CCM.
6. Reconnect the wiring harness.
7. Reconnect the battery.
8. Clear any trouble codes with a scan tool.

Should you do it yourself? If you're comfortable working on cars and have the right tools, you can probably do it. If not, it's best to let a professional handle it.

You have a few choices when buying a CCM:

• Used OEM
• New Aftermarket

Used OEM parts are genuine factory parts. They've been tested and inspected. They're usually cheaper than new parts. You get the quality of the original part at a lower price.

New Aftermarket parts are made by companies other than the original manufacturer. They're brand new and built to meet the original specs.

When replacing the CCM, it's a good idea to check other parts too. These include:

• Wheel speed sensors
• Brake booster
• Wiring harness

Why replace these parts? If they're also failing, they can damage the new CCM. Replacing them together can prevent repeat problems.

How long should a CCM last? Usually, they last for 10-15 years or more.

What can shorten its life?

• Extreme temperatures
• Water damage
• Electrical problems

How much will a CCM cost? It depends on the option you choose.

• Used OEM: $150 - $300
• New Aftermarket: $200 - $400

Labor costs can add to the total. Expect to pay $100 - $200 for labor.

• Total job cost: $250 - $600

Some vehicles have known issues with their CCMs. For example, some models are prone to water damage. Check for any Technical Service Bulletins (TSBs) related to your vehicle. These bulletins can provide helpful information about common problems and fixes. Some owners have reported issues with stabilitrak after CCM replacement, requiring a relearn procedure.

How do you know if the new CCM is working?

• The ABS and traction control lights should turn off.
• The "Service Stabilitrak" message should disappear.
• The brakes should feel normal.
• Use a scan tool to make sure there are no trouble codes.

Listen for any strange noises from the brakes. If everything seems normal, you're good to go.
