Question

a technician is checking the operation of the electronic throttle control (etc) system using a factory or factory - level scan tool. to perform this test on a chrysler vehicle, you would use the \throttle follower test\ as shown on the scan tool. which of the following is needed to perform this process?
a) an assistant to hold open the throttle plate
b) nothing; the throttle will perform a self - test by closing and then opening.
c) a running engine
d) an assistant to check that the throttle plate is moving

Explanation:

For the "throttle follower test" on a Chrysler vehicle's ETC system, the test is designed such that the throttle performs a self - test (closing and then opening) without the need for an assistant to hold the throttle plate, a running engine, or an assistant to check movement. Option A is incorrect as no assistant is needed to hold the plate. Option C is incorrect because the engine does not need to be running. Option D is incorrect as no assistant is needed to check movement. Option B correctly states that the throttle self - tests by closing and then opening.

Answer:

B) Nothing; the throttle will perform a self - test by closing and then opening.
