CHASSIS INFORMATION
DIPLOMAT 2004
The ATC system improves traction on slippery or unstable road surfaces
by limiting excessive drive wheel slip. This is accomplished by limiting
engine torque to the drive wheel or engaging a brake to the spinning drive
wheel. During normal operation engine torque is not affected. The ATC
system works in conjunction with the ABS Electronic Control Unit. The
ECU monitors tone ring speed of the drive wheel in relation to the other
wheels. If a speed differential occurs in the drive wheel, the ECU enters
Automatic Traction Control mode.
During an ATC event, the ECU will automatically react to optimize
traction and safety if the motorhome encounters a slippery road surface.
Engine torque is normally reduced to limit drive wheel slip.
NOTE: The ATC system is always active.
ATC reacts to drive wheel slip by:
• Reducing engine torque to the drive wheel if road speed is above
25 mph.
• Reducing engine torque and activating drive axle brake controls
if road speed is below 25 mph. If the brake control activates, it
remains active regardless of road speed.
