A customer came in with her 2019 Toyota Highlander because the traction control light was showing on the instrument cluster π.
Trust me, some customers donβt want to see ANY warning light on their dashboard unlike some people that will drive like that for months ππ.
As usual, we plugged in our scan tool (the oracle π), and the system displayed C1231 β Steering Angle Sensor Circuit Malfunction
Immediately, from experience, we knew the Steering Angle Sensor (SAS) was faulty.
But we no dey guess at AUTOPATHS LIMITED π
We checked the live data and noticed:
Steering angle not returning to 0Β° when wheel was straight
Readings were unstable
Zero point calibration could not complete
That confirmed it bad SAS.
So we:
π§ Disconnected the battery (airbag safety first)
π§ Removed the steering wheel carefully
π§ Replaced the faulty Steering Angle Sensor
π§ Reassembled properly
π§ Performed Zero Point Calibration with our scanner
And just like thatβ¦ one hand βπ
Traction control light OFF.
System fully restored.
Customer happy.
Moral of the story:
Sometimes itβs just one small sensor disturbing the whole stability system.
