ANTILOCK BRAKE SYSTEM - PUMP MOTOR:
Original pages 5A4-4 AND 8A-44-0 both have the Antilock Brake System Pump Motor wiring drawn incorrectly. Use revised pages 8A-44-0 and
8A-44-1 in place of the original pages. Also what follows is a Pump Motor Circuit Operation description that was not included on original page 8A-44-2.
CIRCUIT OPERATION:
The Antilock Brake Pump Motor is a non-serviceable unit that is contained within the antilock brake assembly. The antilock brake pump motor is
controlled by an internal relay that receives logic signals from the EHCU causing the relay to energize and activate the antilock brake pump motor.
Please mark a reference to this bulletin in your copy(s) of the 1991 Bravada Service Manual at all the affected pages.
