Error Screens
Important: IMPORTANT: The OnGuard collision mitigation system is not operational when an error screen is displayed. If a fault occurs or OnGuard fails to properly track a vehicle, take the vehicle in for service as soon as possible. Standard cruise control will not function with an active OnGuard system fault.
If a system fault is detected, the OnGuard display unit will immediately display an error screen as shown in Fig.. The first error code transmitted will be displayed first; additional faults (if any) can be viewed using the up or down buttons. The display does not show stored fault codes.
See OnGuard™ and OnGuardActive™ Collision Mitigation Systems Maintenance Manual for a full list of error screens and messages. (www.meritorwabco.com).
