for 10 minutes?
• A) To conserve battery power
• B) To prevent the hydraulic fluid from boiling
• C) To prevent the system from overheating
• D) To allow the pumps to reset their internal pressure sensors
Correct Answer: C
The HPG pumps automatically shut down after 10 minutes of continuous operation to prevent

• A) Wheel chock, prevents vehicle from rolling
• B) Ingress tool, locks and unlocks doors
• C) Tow bar adapter, connects towing vehicle
• D) Snatch block, doubles winch capacity
Correct Answer: B
The ingress tool is specifically designed to lock and unlock the JLTV doors when the standard
handles are inaccessible or when the vehicle's electrical system is compromised.
4. What do you do if an item in the Basic Issue Items (BII) appears to be unserviceable?
• A) Discard it immediately and order a replacement
• B) Use it anyway and document the issue later
• C) Request a new one from the supply sergeant

Field Maintenance for evaluation and potential replacement.
5. What is the lowest temperature you should use the arctic kit when starting the vehicle?
,3|Pa g e
• A) 0°F
• B) -20°F
• C) -30°F
• D) -40°F
Correct Answer: D
The arctic kit is designed to assist with starting the JLTV in extreme cold conditions down to -
40°F, below which the vehicle may not reliably start even with the kit.
6. On which variant is the spare tire located at the rear of the vehicle?
• A) UTL only
• B) HGC and CCWC only
• C) CCWC, HGC, and GP
• D) All variants have rear-mounted spare tires
Correct Answer: C
The CCWC, HGC, and GP variants feature the spare tire mounted at the rear, while the UTL
variant has a different configuration for the spare tire storage.
7. Why must you install suspension lock-out braces before crawling under the vehicle?
• A) To prevent the suspension from moving while working
• B) To prevent the vehicle from falling and crushing you
• C) To allow easier access to underside components
• D) To comply with safety inspection requirements
, 4|Pa g e
Correct Answer: B
Suspension lock-out braces are critical safety devices that prevent the vehicle from lowering
unexpectedly and causing serious injury or death to personnel working underneath.
8. While conducting PMCS, you notice the transmission fluid has a small leak but it is not big
enough to form a drop. Classify the leak and decide if you can operate the vehicle.
• A) It is a Class I leak so you can operate the vehicle
• B) It is a Class II leak so you CANNOT operate the vehicle
• C) It is a Class II leak so you can operate the vehicle
• D) It is a Class III leak so you CANNOT operate the vehicle
Correct Answer: A
A Class I leak is defined as seepage that is not large enough to form drops, and the vehicle may
still be operated safely while monitoring the condition.
9. When exiting the JLTV, which direction should the driver be facing and why?
• A) Facing away from the JLTV to see where you are stepping
• B) Facing the JLTV so if you fall, your back hits the ground instead of your face
• C) Facing sideways to maintain balance while exiting
• D) Facing forward to maintain situational awareness
Correct Answer: B
Exiting while facing the vehicle allows you to maintain three points of contact and ensures that if
you fall, your back will absorb the impact rather than your face.
10. Braking while cornering will make the JLTV have a tendency to __.
• A) Oversteer
