Tachometer: Service and Repair
Adjusting Tachometer Night Panel
The Night Panel function in SID turns off the lighting for the tachometer under normal conditions. If engine speed exceeds a given rpm, then the lighting
for the tachometer will light up. This command enables alteration of the engine speed at which the main instrument unit lights up the tachometer when
Night Panel is active. The works setting is 5500 rpm.
Adjustment can be checked afterwards by activating Night Panel with the diagnostic tool.
