RAM 2500 Truck 2WD V8-5.9L VIN 5 HDC (1998)
Maintenance Required Lamp/Indicator: Description and Operation
SERVICE REMINDER INDICATOR (SRI) LAMP
The Service Reminder Indicator (SRI) lamp is used with the 5.9L HDC V-8 gasoline powered engine only. The lamp is displayed on the
instrument panel as the MAINT REQ'D lamp.
The SRI system is incorporated into the powertrain control module (PCM). The PCM records the vehicles mileage and stores it into memory. At
that time, the PCM checks for certain mileage trip points. When the current mileage matches one of the trip points, the SRI lamp is activated.
Certain parts are to be replaced, or certain maintenance must be performed at either an indicated mileage or when the SRI lamp remains on when
the key is in the ON position. After performing the part replacement or required maintenance, the SRI lamp must be reset to turn the lamp off. Use
the DRB scan tool to reset the SRI lamp.
Failure to perform the part replacement or required maintenance and only reset the SRI lamp may be a violation of federal law. Only after
performing the part replacement or required maintenance, should the SRI lamp be reset.
