The vehicle warning lights have illuminated because of an
underlying reason. There is always a reason for the fault.
Sometimes the fault condition has occurred because of a simple
transient and temporary sensor problem. In these cases, when the
fault is cleared, the fault may not return because nothing with the
system is actually broken. While unfortunately sometimes the faults
can be triggered because something is actually physically broken
with the system. In these cases, then physical problem must be
repaired to prevent the fault code from returning. In both cases,
the All Comms Tool will help you diagnose the problem and determine
if expensive repairs are needed or if just a reset of the system is
needed. The reading and clearing of the vehicle fault codes is not
always the final repair step but is a required step on the path to
repairing your vehicle.
