What is wrong
Issue:
On certain trucks, poor signal strength could cause the electronic control unit (ECU) to stop working or not to work properly. As a result, some safety systems may not work, including the antilock braking system, automatic traction control, electronic stability control, active cruise control and the collision mitigation system.
Safety Risks:
Vehicle safety systems that don't work correctly could increase the risk of a crash.
Corrective Actions:
PACCAR will notify owners by mail and advise you to take your truck to a dealership to reprogram the ECU software.
