Safety Recall
The Exterior Lighting Switch (ELS) in certain Model 535, 536, 537, 548, and 567 chassis may not function and can
be reset only by a key cycle. This issue may result in non-compliance with FMVSS/CMVSS 101 and 108.
Affected chassis must have the Vehicle Software updated.
Campaign start date is 03/17/2025.

Introduction
The Exterior Lighting Switch (ELS) in certain Model 535, 536, 537, 548, and 567 chassis may not function and can
be reset only by a key cycle. This issue may result in non-compliance with the following US Federal Motor Vehicle
Safety Standards (FMVSS) or Canadian Motor Vehicle Safety Standards (CMVSS) Regulations:
FMVSS 101 - Controls and Displays
FMVSS 108 - Lamps, Reflective Devices, and Associated Equipment
CMVSS 101 - Controls, Tell-tales, Indicators, and Sources of Illumination
CMVSS 108 - Lamps, Reflective Devices, and Associated Equipment.
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. Failure to adjust the backlight brightness may distract the operator or
make it difficult to see critical safety information, which may increase the risk of a crash.
Warning which can precede condition: None
