Kinetic Dynamic Suspension System: Calibration

HINT:

Perform the calibration of the acceleration sensor zero point by following the procedures below after replacing the acceleration sensor assembly or stabilizer control ECU, or after clearing the ECU memory.

1. PERFORM ZERO POINT CALIBRATION (USING SST CHECK WIRE) 
   NOTE:

   • Do not tilt, move or shake the vehicle during the zero point calibration. Keep it stationary.
   • Be sure to perform the procedures on level ground (inclination of 1% or less).
   1. Clear the zero point calibration value.
      1. Turn the ignition switch to the ON position.
      2. Connect terminals TS and CG of the DLC3 using SST. Perform this procedure 4 times or more within 8 seconds.

         SST 09843-18040 

      3. Disconnect the SST from the terminals of the DLC3.
   2. Obtain the zero point calibration value.
      1. Turn the ignition switch off.

      4. Check that the KDSS indicator light blinks in the pattern shown.

         HINT:

         • The KDSS indicator light blinking pattern changes when the zero point calibration starts and returns to the normal pattern when the calibration ends.
         • The KDSS indicator light does not return to the normal blinking pattern when the zero point calibration cannot be completed.
         • When the zero point calibration cannot be completed, check if the following conditions necessary for performing the calibration are met:
         • Vehicle speed is 0 mph (0 km/h).
         • The acceleration sensor assembly is normal.
         • Acceleration sensor assembly power source voltage is normal.
      5. Disconnect the SST from the DLC3 terminals.
      6. Check that DTC C1779/79  is not output.
      7. Turn the ignition switch off.
2. PERFORM ZERO POINT CALIBRATION (USING INTELLIGENT TESTER) 
   NOTE:

   • Do not tilt, move or shake the vehicle during the zero point calibration. Keep it stationary.
   • Be sure to perform the procedures on level ground (inclination of 1% or less).
   1. Clear and obtain the zero point calibration value.

      1. Connect the intelligent tester to the DLC3.
      2. Turn the ignition switch to the ON position.
      3. Turn the intelligent tester main switch on.
      4. Select the SENSOR ADJUST mode on the intelligent tester.
      5. Clear and obtain the zero point calibration value.
      6. Check that the KDSS indicator light blinks in the pattern shown below.
