WARNING!
After the ABS warning light -K47- and
warning light for brake system -K118-
have illuminated it is possible that the
rear wheels will lock-up earlier when
braking.
If the ABS warning light -K47- (-2-) goes
out but the warning light for brake
system -K118- (-1-) remains on and
three warning tones are audible then the
malfunction may be:
-a- The brake fluid level is too low.
-b- There is a malfunction in the activation
of the warning light for brake system -
K118-.
If the ABS warning light -K47- (-2-) and
the brake system warning light -K118- (-
1-) light up, the ABS system is faulty
and the EBD (Electronic Brake pressure
Distribution) is not functioning.
