looks like you need an ebcm. You can check the ground under the drivers side door attached to the frame, make sure it is clean and tight.



DTC C0241-C0254 or C041-C054
Circuit DescriptionThe ABS relay supplies battery voltage to 6 valve solenoids. The electronic brake control module (EBCM) microprocessor applies the grounds needed to activate each solenoid. The low side of each solenoid coil has a feedback circuit to the EBCM microprocessor. When a solenoid is commanded OFF, the feedback voltage is high. When a solenoid is commanded ON, the feedback voltage is low.
Conditions for Running the DTC • The ignition is ON. • The vehicle speed is greater than 6 km/h (4 mph). Conditions for Setting the DTCThe EBCM detects an internal malfunction.
Action Taken When the DTC Sets C0241, C0242, C0245, C0246, C0251, C0252, C0253, C0254If equipped, the following actions occur:
• The EBCM disables the DRP/ABS. • The ABS indicator turns ON. • The red brake warning indicator turns ON. C0243, C0244, C0247, C0248If equipped, the following actions occur:
• The EBCM disables the ABS. • The ABS indicator turns ON. Conditions for Clearing the DTCThe conditions for setting the DTC are no longer present and you use the scan tool Clear DTCs function.
Diagnostic AidsAn intermittent open/shorted solenoid DTC can be set by several different internal EBCM problems. Replace the EBCM if an open/shorted solenoid DTC continues to set intermittently.

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

05 trailblazer 4.2 Multiple codes Po106, po305, po463, po128, po856 Co298,c0237,c0265,c0245,246, c0241,c0242, c0251,52,c0247,co243 WTF could all this mean


Hi Candice, .How does it run ? P0305 is a misfire code for cylinder #5, P0106 The manifold absolute pressure (MAP) sensor responds to pressure changes in the intake manifold. The pressure changes occur based on the engine load. The MAP sensor has the following circuits:
5-volt reference circuit
• Low reference circuit
• MAP sensor signal circuit
DTC P0128 Engine Coolant Temperature (ECT) Below Thermostat Regulating Temperature
C0237
The EBCM detects an erratic rear wheel speed signal for 105 milliseconds.
DTC C0265 EBCM Motor Relay Circuit
C0265
Thoroughly inspect connections and circuitry that may cause an intermittent malfunction.
• DTC C0241 EBCM Control Valve Circuit
• DTC C0242 EBCM Control Valve Circuit
• DTC C0243 EBCM Control Valve Circuit
• DTC C0244 EBCM Control Valve Circuit
• DTC C0245 EBCM Control Valve Circuit
• DTC C0246 EBCM Control Valve Circuit
• DTC C0247 EBCM Control Valve Circuit
• DTC C0248 EBCM Control Valve Circuit
• DTC C0251 EBCM Control Valve Circuit
• DTC C0252 EBCM Control Valve Circuit
• DTC C0253 EBCM Control Valve Circuit
Sure looks like the ( EBCM ) Electronic Brake Control Module needs to be replaced .All these codes mean The EBCM detects an internal malfunction. Is the abs light on ?

You probably have a problem with one or both of the front brakes - probably a wheel bearing shot and ABS sensor failed or disconnected. I would take to a brake shop immediately, and not attempt a long run with the car.

c0040 indicates right front wheel sensor, so problem is more than likely sensor or wiring to it. c0245 indicates wheel speed sensor frequency error. This confirms wheel sensor or wiring.

You most likely have warped rotors. If they are not too worn, machining them should take care of this, and most parts stores can do this.

it is likely the sensor but I would test it before you replace it. you will need to check the resistance on the wires coming off the sensor you will also need to know what the right resistance is.

Both brake and abs lights are on. I've replaced both front wheel hubs, and checked all fuses.cant seem to locate the problem


you have an ABS code in the ABS computer. You most likely damaged an ABS sensor. even after myouo fix this you will need to get the code cleared
NOTE: autozone wont be able to access the ABS computer.
