It's possible clear a ABS warning light? The car display a Traction Control Fault problem. How it possible clear or reset this messages???

DTC C0550 00: EEPROM Checksum Mismatch . Your best bet , take your vehicle to a qualified repair shop.
Circuit/System Description
When the ignition is turned ON, the microprocessor runs a diagnostic program to detect an internal fault when power up is commanded. If an internal malfunction is detected, the control module will store a DTC C0550 in its memory.

Action Taken When the DTC Sets
If equipped, the following module specific actions may occur:
• The antilock brake system (ABS) indicator turns ON.
• The BRAKE warning indicator turns ON.
• The electronic brake control module (EBCM) disables the ABS/dynamic rear proportion (DRP)/traction control system (TCS).
• The driver information center (DIC) displays the power steering warning message No Steering Assist.
• The TCS indicator turns ON.

As long as your car's brakes work and is safe to drive, take it to any parts store. They have error code readers that can reset these alarms. If they are not able to reset them then you will probably have to take your car to a brake shop for maintenance on your ABS sensors. Traction control is associated with the ABS sensors.

Are you asking why both lights come on at the same time to indicate that those functions are not operational? That is because traction control uses the ABS sensors to operate. If one (or more) of the sensors are bad/not reporting properly, it shuts off both ABS and Traction Control. If you went over a bump or other irregular surface, that could confuse the system and set a fault that could be reset when you restart the car. If it is a more permanent failure where the warning lights stay on after the car is restarted, someone will need to perform a diagnostic procedure to find the fault.

PRE-DIAGNOSTIC INSPECTIONBefore diagnosing ABS/TCS, perform a comprehensive visual inspection of system as follows.Check ABS/TCS wiring harness connectors for looseness. Check harness routing; pay particular attention to wheel speed sensor wiring harness routing. Check fuses No. 1D, 5B and 6B in instrument panel fuse block. Check fuses No. 1 and 2 in underhood fuse block. Check brake fluid level in master cylinder reservoir. Check brake fluid level in Pressure Modulator Valve (PMV) assembly reservoir. Ensure parking brake is fully released. Ensure parking brake switch is functioning properly. Always perform ABS/TCS system functional check before using DIAGNOSTIC CODE CHARTSThe EBCM/EBTCM has self-diagnostic capability, which can detect system failures. Fault codes stored by EBCM/EBTCM can be displayed using Tech 1 scan tester. There are no provisions for flash code diagnostics.Begin ABS/TCS diagnosis with PRE-DIAGNOSTIC INSPECTION procedure. If failures are found during pre-diagnostic inspection, perform necessary repairs, and proceed with ABS/TCS FUNCTIONAL CHECK. See Fig. 5 .If no failures are found during pre-diagnostic inspection, go to ABS/TCS FUNCTIONAL CHECK. See Fig. 5 . The ABS/TCS FUNCTIONAL CHECK will either indicate ABS/TCS is functioning properly or direct technician to various diagnostic procedures such as diagnostic charts, symptom diagnosis or BRAKE warning light diagnosis.CHART D - TRACTION OFF WARNING LIGHT ON CONTINUOUSLY & NO DTC SET (BUICK WITH UH8 OR U2A INSTRUMENT CLUSTER)Circuit DescriptionWhen ignition switch is first turned to RUN position, EBTCM goes through a self-test, which lasts 2-4 seconds. During self-test, EBTCM commands TRACTION OFF indicator warning light on. Powertrain Control Module (PCM) can also command EBTCM to set a Code 75 which will illuminate TRACTION OFF indicator.Traction control switch is located either on instrument panel center trim plate or driver's front door trim panel. Switch allows driver to select traction control mode (on/off). When traction control system is turned off, TRACTION OFF warning light comes on.EBTCM monitors transaxle temperature through

TC = Traction Active

If your vehicle is equipped with the Traction Control system, this message will stay on a few seconds after the traction system stops limiting wheel spin.

This message will appear when the traction control system is limiting wheel spin. Keep in mind that when the warning lights turn on, a fault code is stored in the ABS control module (in this case). Retrieving, diagnosing, and repairing any ABS system faults will be necessary to keep the light off. A common fault with ABS systems are the wheel speed sensors, stored codes may confirm this.

Hope this helps.

If the ABS (and likely the traction control) light came on at the same time that the speedometer stopped working, you likely have a faulty wheel speed sensor at the right rear wheel. You can test this by swapping the two rear wheel speed sensors (ABS sensors). If the speedometer then works (but the ABS & Traction control lights stay on), replace the sensor that is now at the left rear (was at the right rear). If no change, you may have a fault in the ABS & Traction control - control unit.

Your best to get the system "code read". Withhout seeing the carits impossible to say, it could be anything. Sensor failure, wiring fault etc. Make friends with a good Mechanic.

Sounds like they may have left something disconnected like the ABS/ Traction control wheel sensor, make them fix it!!
