An Emission Maintenance Reminder (EMR) lamp is used on most 1989-93 vehicles. The lamp illuminates to remind the driver that certain critical emissions maintenance procedures must be performed. The lamp will stay illuminated until reset.
- A Chrysler Digital Read Out Box II (DRB-II) or equivalent scan tool is necessary to perform this procedure.
- Connect the scan tool to the vehicle's diagnostic connector.
- Follow the scan tool manufacturer's instructions regarding EMR lamp reset procedures.
- These procedures reset the EMR timing in the computer and will turn off the reminder light.
