Collision Mitigation System (CMS)
Collision Mitigation System (CMS) is integral to the OnGuard™
Collision Safety System. The system will provide driver alerts with
both a visual and audible alarm through an in-cab dash display when
the vehicles following distance could result in a rear-end collision. If a
potential rear-end collision is developing and the driver does not take
action to decelerate the vehicle, OnGuard™'s Active Braking
automatically de-throttles the engine, applies the engine and
foundation brakes to provide up to 0.35Gs of braking power. This
Active Braking application is intended only to provide early braking as
the driver is recognizing and reacting to the situation — the driver
must take the appropriate corrective action in response to the
collision warning. The OnGuard™ Collision Safety System will not
become active below 15 mph.
Error Screens
If a system fault is detected, the display will switch immediately to
the error screen. Figure 10. On this screen, the first error code
transmitted will be displayed. The UP/DOWN buttons will display
additional faults if there is more than one current error. Refer to
Maintenance Manual MM-0951, OnGuard™ Collision Safety
System, for a full list of faults.
The display does not show stored fault codes.
NOTE: OnGuard™ does NOT function when any error screen is on
the display (Figure 10, Figure 11 and Figure 12).
Figure 10
If there is no communication between the OnGuard™ display and
the radar sensor, an error screen indicating a broken data link to the
OnGuard™ radar sensor will show. The display background is red.
Figure 11.
Figure 11
If the OnGuard™ display shows a red screen with the message
“Mode 6 Error”, the display is not able to correctly process error
messages that the display is receiving from the radar sensor.
Contact your vehicle manufacturer dealer or ArvinMeritor Customer
Service Center at 800-535-5560 for further instructions. Figure 12.
Figure 12
ACC or CWS Failure
If there is a fault in the system, the CWS may not emit collision
warnings or apply braking. If this occurs, take the vehicle in for
service as soon as possible. Standard cruise control will not function
with an active OnGuard™ system fault.
Additional OnGuard™ Display Features
Access the Additional Features menus by pressing the MODE key
from the CWS and ACC main operating screens. All screens are
accessible while moving. Depending on the software version of the
display, most will automatically return to the main screen if no key is
pressed for 60 seconds. The Radar Alignment screen does not
automatically return to the main screen.
