Maintenance Required Lamp/Indicator: Description and Operation

SERVICE VEHICLE INDICATOR
The "SERVICE VEHICLE", this 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). The "SERVICE VEHICLE" 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" indicator will come on and stay on while the malfunction is taking place. If a malfunction is intermittent, the "SERVICE VEHICLE" indicator that came on will go out when the malfunction is no longer detected by the computer.
