On a small number of trucks, the rearview camera wiring harness may not have been manufactured correctly and could short circuit. If this happens, the rearview camera image may not appear on the display. Canadian regulations require the rearview image to display when the transmission is shifted into reverse gear.
A rearview camera image that doesn't display could reduce a driver's ability to see behind the vehicle while backing up. This could increase the risk of a crash.
All of the affected trucks have been repaired. The rearview camera wiring harness was replaced.
