Yellow light on MOT

helpneeded2014

My car has got a yellow light because the traction control don't work, i was told for the last 5 years it's not a fail and was wondering if anything had changed this year ?

What car? Is it JUST traction control, or is it ESP stability control?

If just TC, then you should be OK.
If it's ESP, then it's a fail.

The difference is that TC simply stops wheelspin, ESP tries to "catch" the car if you lose grip.

7.12 Electronic stability control (ESC)
You must check all vehicles fitted with electronic stability control other than Class 3 vehicles.

Electronic stability control is also referred to as ESC, ESP, VDC, and DSC, among many other names. Some systems may be able to be switched off by a switch, whilst others might only be able to be switched off using an electronic menu system.

The dashboard warning lamp for these systems might take various forms and you should only fail a vehicle if you're certain that the warning lamp is indicating an ESC malfunction. You might need to check the owner’s handbook.

a. Wheel speed sensors missing or damaged - Major
b. ESC wiring damaged - Major
c. Other ESC component missing or damaged - Major
d. ESC switch damaged or not functioning correctly - Major
e. ESC MIL indicates a system malfunction - Major
