Question about 2004 Chevrolet TrailBlazer

1 Answer

My 2004 chevy trailblazer is skipping and sputtering badly. Also, the service engine light stays on. Sometimes it is just illuminated, and sometimes it flashes. If I turn the a/c on, the engine dies. I have replaced a coil pack or two before, with improved performance. Could this be a cylinder?

    What is the check engine light code(s)? It will be a letter followed by four numbers.

When the check engine light is flashing, it indicates a serious condition. You need to have the car scanned for trouble codes and diagnosed, making guesses is going to waste money.

Abslight stays on. How to fix? This is a2007trailblazer?


First you need to have EBCM - electronic brake control module check for DTC'S - diagnostic trouble code's . If the light is on there is a code stored . I think most part stores can do this and for free . After you find out what code is stored , looking up that code in service repair information for diagnostic trouble shooting chart would be next step . There are a few codes too.
DTC C0035 or C0040
DTC C0045 or C0050
DTC C0110
DTC C0131
DTC C0161
DTC C0186
DTC C0196
DTC C0201
DTC C0240
DTC C0241 or P0856
DTC C0244 or P1689
DTC C0245
DTC C0283
DTC C0287
DTC C0290 or C0292
DTC C0455
DTC C0550
DTC C0558

Find the code do the diagnostic's , fix the problem , wiring issue's , a sensor , bad module ,what ever it is . The light will go out then . Here is a sample of code discription .
• DTC C0035 Left Front Wheel Speed Sensor Circuit
• DTC C0040 Right Front Wheel Speed Sensor Circuit

2003 chevy trailblazer service engine soon light


If the service engine soon light is flashing, it means the computer has detected an engine misfire with the potential of catalytic convertor failure. Don't just tune it up. Bring it somewhere they can read the trouble code. Sometimes it will designate which cylinder is having the problem.

Service engine soon


hi, this is just a reset issue. sometimes the CPU can become confused. the original warning that informed you about your gas cap is still in the cpu's memory. you will have to reset the cpu and, this will clear the warning. After the reset, it will stay off. chevy cpu's tend to do this from time to time.
