S100 Traction Control

Post by John Loudon »

Hi,

I have TC wired for all 4 wheels on my car to an S100. Should I be able to test that the wheel speed sensors are giving a signal with just the ignition on via the Traction Control Info page under Display and Test functions? If I switch the TC on, the Control Switch field changes to ON and the Control Enabled in map changes to Y but I ask as I have the car jacked up and I am rotating wheels but seeing no output on the page except for Actual Slip % changing to 100% once per wheel revolution but nothing on the oscilloscope area of the display. Does the minimum speed to activate have to be reached to see a signal from the wheel speed sensor to see something? Anything else I am missing?

Thanks

John

I'm near sure the engine has to be running.

Although in diagnostic display you should be able to see the wheel pulses count up with the engine off I think.

Thanks. All sorted. Gap between the sensors and trigger wheels was too much Now adjusted and getting speeds on all 4 wheels
