DTC C0035-C0051
Circuit Description
As the wheel spins, the wheel speed sensor produces an AC signal. The EBCM uses the frequency of the AC signal to calculate the wheel speed.
DTC C0244 or P1689
Circuit Description
Traction Control is simultaneously controlled by the EBCM and the PCM. The PCM sends a DELIVERED TORQUE message via a Pulse Width Modulated (PWM) signal to the EBCM confirming the delivered torque level for proper Traction Control system operation. The EBCM supplies the pull up voltage.
DTC C0550
DTC C0550 is set when an internal EBCM malfunction exists.
Yeah , I'd say they were all related - electronic brake control module- ABS
What it looks like:
The traction control warning light typically takes the form of the acronym "TC." Sometimes this light is a small illuminated picture of a car losing control

How this system works:
Traction control uses wheel speed sensors to detect when one or more of the car's wheels lose grip and traction. When the system registers a loss of traction in one or more of the wheels, a computer will limit power to the wheels that are still in solid contact with the road to prevent a skid.
Common reasons for this to happen:
ABS is malfunctioning: Traction control and ABS (anti-lock braking system) often share the same control module and internal self-diagnostics system. As a result, sometimes an issue in the ABS can trigger the traction control light. If this is the case, then both the ABS and Traction Control lights will be on.
Broken wheel speed sensors: Wheel speed sensors are usually in the wheel bearing assembly, and determine the rate at which each wheel is moving. The sensors relay that information to the traction control module, which determines whether or not power needs to be shifted. Wheel speed sensors can get dirty or damaged and stop working, which prohibits the traction control module from knowing when to enable the system.Traction control module is faulty: The traction control module - which, again, is often shared with the ABS - can malfunction and break altogether, causing the system to stop working.
What to expect:
A top-rated mobile mechanic will come to your home or office to determine the source and cause of the traction control issue, and will then provide a detailed inspection report that includes the scope and cost of the necessary repairs.
How important is this service?
It's important to have the traction control issue investigated as soon as possible, as adverse driving conditions can arise at any time. While your car is unlikely to incur further damage from a faulty traction control system, it won't be safe to drive in rain, snow, sleet, or other inclement weather, or even possibly through pools of water on the road. Furthermore, the issue that is causing the traction control light to illuminate could also be impacting the ABS.

Your abs and traction control lights should only come on when you start to slide while breaking(ABS), and when your wheels spin in place when excelerating(TC). If those 2 things don't happen, which with some people they never do, you should never see the lights come on. Only when those mechanisms are in use do the lights come on. And they will always flicker as that is what abs and tc are, intermitant surges to break up the constant. ABS does this for obvious reasons...anti lock break, so when you slide, the abs "taps" the breaks in short bursts so they don't lock up. TC "taps" the exclelrator when it slips. Those "taps" are what trigger the lights on your dash, which is why they flicker and don't stay on.
i have same probleme with my land rover, this trouble is intermitant wath can i do abs light traction control andhill descent if you have he ansher for me [email protected] thank you
If the sensor didn't fix the problem, then it's most likely a wiring harness issue. A bad sensor/harness will turn off the ABS & traction control and turn on both ABS and Traction lights. time to troubleshoot the wiring harness for continuity/short between the sensor and the computer.
You need to have your brakes inspected by a professional. The lights indicate that ABS and traction control are not working...although brakes will work without these features, a humming noise can indicate more problems to come.
