The PCM requests that the message be displayed via class 2 serial data message. The message indicates that the PCM has limited the vehicle speed to one of the following: " Top speed

" Reduced speed due to a concern in the road sensing suspension system.

The XXX will be replaced by the actual speed limit value and in the units currently displayed on the speedometer.

Have it scanned for codes.
