10.10.6. Diagnosis
 Integrated analogical valves for an optimised controllability
 5 integrated pressure sensores (front brake circuit, wheel
specific brake pressures)
 Directly wired wheel speed sensors (transmitted to MoTeC via
CAN)
Due to the optimum brake performance it is not recommended to turn the
system off. Under certain conditions e.g. adjusting the balance bar brake
system, braking in new brake pads or brake discs it could be necessary
to switch off the system. Therefore, the switch in centre console must be
flipped.
When ABS is turned off an alarm appears in the MoTeC display and the
outer LEDs start to flash. By pushing the alarm button on the steering
wheel the alarm disappears. The alarm gets active again 45 seconds after
the alarm button has been pushed.
In case of a system failure the outer LED's on the shift light module start
to flash and the message „ABS Error" is displayed in the MoTeC dash.
The alarm disappears after 5 seconds automatically if the alarm button on
the steering wheel is not pushed to turn off the alarm. Nevertheless, the
alarm message appears again on the display after 45 seconds.
System errors can be caused by either a malfunction of the acceleration /
yaw sensor or a failure of one of the wheel speed sensors.
