Question

To test the low pressure warning signal, you should do all BUT the following...

A) shut the engine off
B) turn the electrical power on
C) ask a friend to listen for the signal
D) step on and off the brake pedal to reduce air pressure

Answer 1

To test the low pressure warning signal, you should not step on and off the brake pedal to reduce air pressure.

Step-by-step explanation:

To test the low pressure warning signal, you should do all BUT the following:

1. Shut the engine off
2. Turn the electrical power on
3. Ask a friend to listen for the signal
4. Step on and off the brake pedal to reduce air pressure

Stepping on and off the brake pedal would generate more air pressure rather than reducing it, so this is the action you should not do when testing the low pressure warning signal.
