Emission Control System Service Indicator Reset — US Models (Discovery 1)

Maintenance of the toxicity reduction system is carried out after 85,000 km and 170,000 km of mileage. At the right moment, a red indicator lights up on the instrument panel "Service Engine" (engine maintenance). In this case, the vehicle must be taken to a service station, where a new plug will be installed on the control unit, resetting the mileage interval:

• 1. The control unit is located at the passenger's feet.
• 2. Determine the characteristics of the control unit and remove the plug.
• 3. Remove the sticker to access the reset hole.
• 4. Insert a thin metal rod into the hole and momentarily short-circuit the two terminals located in the hole.
