Maintenance Required Lamp/Indicator: Description and Operation
SERVICE VEHICLE SOON INDICATOR
The "SERVICE VEHICLE SOON" indicator is used to inform the technician that a Non-Emissions releated malfunction of the Computerized Engine
Control System or Body Control System has occurred, (a DTC has occurred). This light does not indicate a maintenance service is needed. The
"SERVICE VEHICLE SOON" indicator is checked for proper operation while the engine is cranking, and will turn off after the engine is running.
Depending on the trouble code set, the "SERVICE VEHICLE SOON" indicator will come on and stay on while the malfunction is taking place. If a
malfunction is intermittent, the "SERVICE VEHICLE SOON" indicator that came on will go out when the malfunction is no longer detected by the
computer.
