How do I fix a Speed Signal fault?

Modified on Thu, 26 Feb at 9:04 AM

Clear the fault by isolating the vehicle power supply at batteries for at least 1 second and then reactivate the power supply to the vehicle, allowing time for GSP Lock to be achieved.

Check no engine lights on vehicle / speedometer work.

Check CAN line Voltages to MSB as per diagnostic guide.

Check DIP switch 3 set to ON as per diagnostic guide.

Check CAN Display connector not connected to screen harness. Refer to schematic; check that VEH CAN not ticked in screen setting menu. 

For full list of diagnostic steps refer to MSARB Diagnostic Troubleshooting Guide – for Speed Signal.
