Where is the ABS malfunction lamp for the trailer itself commonly mounted (in addition to any dash lamp)?
- A.On the left side of the trailer near the rear (the roadside-rear corner area)
- B.On the roof of the trailer at the front
- C.Inside the trailer cargo compartment
- D.On the landing gear crank handle
Correct answer
A. On the left side of the trailer near the rear (the roadside-rear corner area)
Why
Trailers built with ABS carry an external yellow lamp, traditionally at the left rear, so it can be seen in the mirror and during walk-around checks. Watching it cycle at power-up is part of checking a trailer you have just coupled.
