1985 Buick Skylark Custom, 2.8 W, StandardFACTORY OEM SERVICE PROCEDURE

Using DIC Reset Button

  1. Turn ignition switch to OFF position.
  2. Ensure all tire pressures are adjusted to the pressure recommended on tire pressure label.
  3. Turn ignition ON with engine OFF.
  4. Press SELECT right arrow button until "GAGE" is displayed.
  5. Press SELECT down arrow button until "TIRE PRESSURE" is displayed.
  6. Press and hold RESET button until "TIRE PRESSURE RESET" is displayed.
  7. Release RESET button. DIC should display "TIRE PRESSURE NORMAL".
  8. After resetting, the TPM system requires up to 30 minutes of straight line driving in each of the following speed ranges to complete calibration process:
    • 15-40 mph (24-64 km/h).
    • 40-70 mph (64-113 km/h).
    • 70-90 mph (113-145 km/h).
    NOTE: The EBCM learns tire pressure calibration for each speed range independently. In Monitor Mode 1, EBCM has only partially learned tire pressure calibration for speed range and has limited detection capability for a tire pressure condition. In Monitor Mode 2, EBCM has fully learned tire pressure calibration for speed range and has full detection capability for a tire pressure condition.
