Speedometer Module: Description and Operation
The analogue speedometer in this vehicle is controlled by a steeper motor measuring mechanism actuated by a stepper motor driver. The input to the speedometer is supplied exclusively by the Electronic Brake
Traction Control Module (EBTCM). The maximum display readout range is
185 degrees of pointer sweep. With power applied to the speedometer the speedometer pointer is moved back to the internal stop for zero point recognition (restart). Without power to the speedometer the pointer is not moved back to the zero position. The speedometer display accuracy tolerance is accurate to within
+/- 2.0 degrees of needle sweep.
