From time to time over the last few years (100KLM) the ABS light has come on.
Usually cleared itself after several trip cycles. The last month more frequently.
until it stayed on all the time. All other operation remains normal.
last week removed the wheel speed sensors and cleaned rust which had accumulated from the wheel disk splash guard on the sensor (Magnetic). This restored Abs function after several drive cycles. All well for 3 days. Then triggered again.ThisABS,ETSalways is triggered when reversing the vehicle and in the first few wheel revolutions.
I finally relented and found a mechanic that had a code reader that could interpret the error codes stored in memory. (You get what you pay for in a mechanic, a story for another day)
The code from the X431 Tool Report
C1140 Steering angle sensor (N49)
Steering angle sensor is not initialized
135 Sporadically fault in CAN communication with:Motor electronics
146 Sporadically Rpm n3 too high Externally toothed disc carrier
Where is the Steering angle sensor located? What is a toothed disk carrier?
I have located a sensor on the rack and pinion box. Is the disk carrier the speed wheel sensor?
Any help is appreciated
