driving test
The ESP driving test is used to check the
plausibility of the signals from sensor for
transverse acceleration -G200-, sender for
rotation rate -G202- and sender 1 for brake
booster -G201-.
The ESP driving test should be performed each
time parts of the ESP system are removed or
replaced.
