ONE OF THE FAULTS THAT COMES TO MIND, IS A MISSING VEHICLE SPEED SIGNAL FROM THE ABS MODULE, WHICH CAN AFFECT THE OPERATION OF THE SPEEDOMETER. ALL THE SYMPTUMS YOU ARE NOTING CAN BE RELATED TO SEVERAL DIFFERENT COMPONENTS: ABS MODULE; DISPLAY INFORMATION MODULE; CONTACT REEL; CENTRAL ELECTRONIC MODULE; ETC. THE BEST SCENARIO IS TAKING IT TO A DEALER FOR DIAGNOSIS. THIS WAY THEY CAN PULL THE FAULT CODES AND DETERMINE WHAT THE VEHICLE NEEDS. MAYBE IT WILL BE JUST A MATTER OF PERFORMING A SOFTWARE UPGRADE TO ONE OF THE MODULES. THERE ARE JUST TOO MANY POSSIBILITIES IN REGARDS TO REPAIRS.
