ASE A6 Practice Test (2025-2026) Electrical
Electronic Systems Exam 5 Guide
1. A late-model vehicle is being diagnosed for an inoper- A
ative heated steering wheel. Technician A says that a
faulty clock spring could cause this problem. Techni-
cian B says that the steering wheel heater grid can be
replaced with out removing the steering wheel. Who is
correct?
A. A only
B. B only
C. Both A and B
D. Neither A nor B
2. The circuit in the figure above is a 12 volt circuit and C ( there is voltage drop,
the battery is fully charged. Technician A says that the can be before or after the
switch could have burnt contacts. Technician B says load )
that the circuit could have a poor ground connection.
Who is correct?
A. A only
B. B only
C. Both A and B
D. Neither A nor B
3. Technician A says that high current draw can be caused-B
by dirty electrical connections. Technician B says that
low current draw can be caused by corroded electrical
connections.
