- Now perform test drive for maximum 50 seconds
at a speed of 15km/h...30km/h:

It must be driven so that no ABS, EDL, ASR or
ESP regulation is performed.

Make a turn with steering wheel turned at least
90 .
When the ABS warning lamp -K47- and ESP
warning lamp -K155- go out, the ESP driving
test has been successfully completed.

WARNING!

Always comply with road traffic regulations
and drive according to the traffic conditions.

Note:

If the ABS warning light -K47- does not go out,
then the ESP driving test has not been
performed correctly.

If the ABS warning light -K47- does not go out
and the ESP control lamp -K155- lights up
again, check DTC memory Page 01

If the measured figures only deviate slightly from the specifications, clean sockets and plugs
of the testers and adapter cables (with contact spray G 000 700 04 ) and repeat check.
Before replacing components, check wiring and connections and also, particularly for
specifications of less than 10 , repeat resistance check on the component.
