So, if I start my car without immediately disabling traction control, my car runs really terrible. Like it'll barely chug along. But if I turn it off, it drives and runs like a brand new car. But here is my main concern, if I do not get it turned off in time, the message on my DIC says "Traction control activated" (while I am still in park). Then my entire car makes this really loud vibrating noise. Any idea what the main cause could be and what I have to do to fix this? It is driving me crazy.

Welcome to 2CarPros.

For some reason the vehicle thinks it is spinning the tires or sliding.As a result, engine power is reduced. Here is the definition for what you described:

Traction Control Active Message
The traction active message when engine torque reduction or brake pressure application is required to maintain traction. The EBCM (electronic brake control module) sends a serial data message to the DIC requesting this display.

Okay, now the issues is what is tricking the vehicle into this problem. It could be a vehicle wheel speed sensor or the EBCM itself. What needs to be done is to have the computer scanned for diagnostic trouble codes. These codes will point us in the right direction for repair.

The easiest thing to check without a scanner are fuses. There are three I need you to inspect. I attached a pic of the fuses below and circled the ones in question. They are in the under hood fuse / relay box.

Here are a few links to help with checking:

If, however, you want to test the wheel speed sensors yourself, here is a link that explains how it is done:

If you look at picture 2, it shows the sensor locations. There is one at each wheel. Here is a legend do you can identify each one:

1 - Wheel Speed Sensor (WSS) - LF
2 - Wheel Speed Sensor (WSS) - RF
3 - Wheel Speed Sensor (WSS) - LR
4 - Wheel Speed Sensor (WSS) - RR

Let me know what you find. Also, if the fuses are good, have the computer scanned for codes. Often times a parts store will do it for free.

Take care,
Joe
