Emission Maintenance Reminder (EMR) Light

This output device is located in the instrument panel, and its purpose is to inform the driver that the vehicle requires scheduled maintenance for certain emission system components. The SBEC illuminates this lamp at certain mileage intervals. The controller keeps track of the vehicle mileage by monitoring the vehicle distance (speed) sensor. The EMR Lamp illuminates at 60,000 mi, 82,500 mi, and 120,000 mi.

The EMR light can ONLY be reset through the use of a SCAN TOOL. If the engine controller is replaced, the current mileage of the vehicle needs to be entered into the EMR memory. For more instruction refer to Powertrain Management/Computers and Control Systems/Testing and Inspection/Procedures.

The manufacturer recommends performing the following procedures at these intervals:

60,000 miles

Clean EGR passage
Replace PCV Valve



82,500 miles
Replace Oxygen Sensor



120,000 miles
