Notice:

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.
