Original page 8A-33-0 is replaced with new page 8A-33-0. See this bulletin. Original page 8A-33-1 should have included the following:
The Vehicle Speed Sensor Buffer (DRAC) module processes inputs from the Vehicle Speed Sensor (VSS) through circuits 821 and 822. These circuits
are twisted pair wires and provide an AC signal to the module corresponding to the rotation of the VSS. Connector C2 at DRAC Module on page
8A-34-0 should be updated to read C228B. Use the diagnostic charts provided with this bulletin when servicing the 1991 Bravada Vehicle Speed Sensor
Buffer (DRAC).
