Test E

PINPOINT TEST E: THE SPEED CONTROL DOES NOT DISENGAGE WHEN THE BRAKES ARE APPLIED


Test E1-E2:






Test E3-E5:






Normal Operation
When the speed control actuator no longer senses power on circuit 535 (LB/RD), the speed control actuator deactivates the speed control system. When the brake pedal is applied and the speed control deactivator switch opens, battery voltage is removed from circuit 535 (LB/RD) to the speed control actuator.

Possible Causes
- BEC
- circuit 535 (LB/RD) shorted to power
- speed control deactivator switch
- stoplamp switch
- speed control actuator
