Traction control and abs lights on intermittently traction control fault message displayed intermittently

Need to have it check for trouble codes

Do you know what diagnostic flow charts are ? Every DTC has a factory diagnostic test's to test electrical circuit's , computer , sensor's etc...
DTC C0561 System Disabled Information Stored
The electronic brake control module (EBCM) disables the traction control when other electronic control modules set DTCs for components that effect the operation of the traction control system.
The PCM or BCM diagnoses a condition preventing the engine control portion of the traction control function and sends a serial data message to the EBCM indicating that torque reduction is not allowed. The PCM or BCM will typically set a DTC and the EBCM will set this DTC.
Diagnostic Aids
This DTC is for information only. As an aid to the technician, this DTC indicates that there are no problems in the ABS/TCS system.
.
DTC C0242 PCM Indicated TCS Malfunction
The electronic brake control module (EBCM) and the powertrain control module (PCM) simultaneously control the traction control. The EBCM sends a serial data message to the PCM requesting torque reduction. When certain PCM DTCs are set, the PCM will not be able to perform the torque reduction for traction control. A serial data message is sent to the EBCM indicating that traction control is not allowed.

This DTC is for information only. As an aid to the technician, this DTC indicates that there are no problems in the ABS/TCS system.



Your best bet , take it to the dealer where they have factory scanner an can read the info you can't.

First you'll need to take it to have DTC's - diagnostic trouble codes check to find out what part of the system is at fault ! Could have a sensor , control module ,or wiring problem !
Traction Off Indicator The traction off indicator, which is a LED located on the traction control switch, illuminates only when the traction control switch has been pressed and released, disabling traction control. It is important to note that a traction fault does not illuminate this indicator and that there is no relationship between this indicator and the traction fault message.
Traction Fault Message The IPC displays the traction fault message when either of the following instances occur.
?€¢
The EBCM detects a malfunction that requires traction control to be disabled. The EBCM sends a serial data message to the IPC requesting that the message be displayed.

?€¢
The IPC detects a loss of serial data communication with the EBCM

Traction Control System (TCS)
When drive wheel slip is noted while the brake is not applied, the EBCM will enter traction control mode.
The EBCM uses a 5-volt pulse-width modulated (PWM) signal to request the PCM to reduce the amount of torque to the drive wheels. The PCM reduces torque to the drive wheels by retarding spark timing and by commanding the throttle actuator control. The PCM uses a 5-volt PWM signal in order to report to the EBCM the amount of torque delivered to the drive wheels.
You would need a factory grade scan tool to check data PID's - parameter identification , all the sensors work within a specific voltage range 1- 5 volts an you can see this on a good scan tool !
The Traction control is part of the ABS system an there a several DTC possible
DTC B0827 DTC B0828 DTC B2745 DTC C0035 DTC C0035 or C0040 DTC C0040 DTC C0055 DTC C0110 DTC C0191 DTC C0201 DTC C0220-C0229 DTC C0240 or P0856 DTC C0244 or P1689 DTC C0245 DTC C0267 or C0268 and C067 or C068 DTC C0550 DTC C0899 DTC C0900
You best bet is to take it to a qualified repair shop !

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.

This could be and indicator that an abs sensor has gone bad or intermittently losing its signal. This may require replacement of a bearing hub asembly in which the abs sensor is incorporated into.The traction control uses the abs to control slipping when traction is limited. If the abs becomes disabled the traction control does as well.

IF YOU ALREADY HAVE THE ABS FIXED THE LIGTH AUTOMATYCALY TURNS OFF BUT IF THE ABS IS STILL UNABLE THE ABS LIGTH AND THE TRAC OFF LIGTH WILL REMAIN ON

If you have abs sensors at the wheels, have them checked. Usually abs & trac control work off these sensors

I agree with the post about the tail lights. And the symptom about the brakes on when starting was also helpful. When I took off my rear tail lights and removed the top light bulb (top of the 4 is closest to connector) then repeat starting the car the problem is gone. I have a whole drawer of these bulbs that I removed, not because the filament was burned out, but because the base (similar to circuit card edge connector) had heat damage and melted. I am not sure exactly what the problem is but I think there are multiple conductors in the fixture which are too close or get moisture shorts. Anyway I hypothesize the circuit for daytime running lights is leaking current into the brake light circuit, and it causes that module that controls traction control and ABS to declare a fault. When you start with foot on the brakes the brake lamp is pulled on (I don't know if switches hi or lo) so that module doesn't declare the fault until you release the brakes.

I put in new bulbs and it works fine for now, but I know it may reappear some day then I will repeat, disassembly of the fixtures and inspect bulb bases for heat damage and clean out and replace. That is what did the trick for me.

Thanks Fixya and all contributors
