Custom Cruiser RWD V8-350 5.7L (1992)
1992 "B" cars were built with a cruise control module that has to have the brake signal input pulled low at terminal "G" for cruise control to function.
This is accomplished by a small amount of current flowing from the cruise module, through circuit 820, to the Center High Mounted Stop Lamp
(CHMSL) bulb to ground. When the brakes are applled and the brake switch closes, the cruise module and circuit 820 receive BATT (battery) voltage.
This allows the CHMSL bulb to illuminate and the cruise module to sense that the brakes are applied. The brake switch mechanization, as shown on page
BA-34-0, has been re-drawn to show it in the "normally open" state. The new diagram is printed on the back of this bulletin.
In addition, please add the following to step 2 of the Troubleshooting Hints on page 8A-34-1 of your Custom Cruiser Service Manual.
