In accordance with the Canada Motor Vehicle Safety Act, PACCAR Inc has determined to recall the vehicles below.

Manufacturer

Peterbilt Motors Company, 1700 Woodbrook Street, Denton, TX 76205

Description of Defect/Non-compliance

The Exterior Lighting Switch (ELS) in certain vehicles may not function. It is non-responsive and can be reset only by a key cycle. This issue may result in non-compliance with FMVSS/CMVSS 101 and 108.

Safety Risk

If the ELS fails, the hazard lights and the backlight brightness adjustment may not function. As a result, the lack of hazard lights may not alert other drivers and failure to adjust the backlight brightness may distract the operator, which may increase the risk of a crash.

Cause

In some engine start conditions, the ELS power may drop below 10V for an extended period and prevent the ELS from properly powering on.
