MULTIFUNCTION TURN SIGNAL STALK, CHASSIS NODE & CHASSIS
LOAD CENTER
Kenworth introduced the chassis node and chassis load center with 2010 emissions. The information that follows covers
the functions of the chassis node, along with guidelines for installing additional lights on the chassis.
Exterior Lighting Circuit Limits
The multifunction turn signal stalk communicates to the CECU inside the cab which sends information to the Chassis
Node over the F-CAN bus. The Chassis Node then activates the load requested, drawing power from the chassis PDC.
The Chassis Node is designed to operate within specific current limits for
•
Headlamps
•
Fog lamps
•
Vehicle stop/turn signal lamps
•
Trailer turn/vehicle forward side facing turn signal lamps
•
Back Up Alarm
•
Windshield Washer Pump
If the current limits for any of these circuits are exceeded, the Chassis Node will default to a protection mode, causing the
lamps to not function properly but still providing sufficient lighting for safe operation of the vehicle. See TABLE 6-3 for load
limits.
The vehicle can exceed current ratings on a particular circuit in two ways
•
Installing too many lamps on a circuit
•
Using bulbs of excessive wattage
The following table is a recommended guideline to avoid exceeding the current limits of the Chassis Node. The Chassis
Node receives power from the chassis PDC, see Figure 8-24.
