it illuminates if there is a malfunction in the ABS, since the ESP
is part of the ABS system.
If the ESP warning/indicator light illuminates and stays on after you
have started the engine , this may mean that the control system has
temporari ly switched off the ESP. If this is case, you can reactivate
the ESP by switching the ignition off and then on again. The
warning/indicator light should go out to show that the system is
fully functional again.
If the battery terminals were disconnected and re-connected, the
vehic le was jump started or the battery is very weak, the ESP sensor
system goes through a learning process for the first few yards.
During this time, the indicator light illuminates. It goes out as soon
as the learning process is comp lete .
