Calibration Procedure

WARNING: This page is about a different car, the 2015 Cadillac SRX. However, it is still accessible from the selected car via links, so may be relevant.
  1. Verify no other DTCs except for B101E 4B Electronic Control Unit Software are present.
    • If other DTCs are present 

      Refer to service information and repair as necessary.

    • If no other DTCs are present 
  2. Prior to driving the vehicle make sure the surface in front of the radar (Cadillac emblem) is clean. Also verify the mounting area is not damaged and allows the module to face the intended direction.
  3. Prepare scantool to be mobile for Long Range Radar Calibration driving phase. The scantool needs to stay connected during the driving phase of the calibration.
  4. Engine running.
  5. Initiate calibration using Long Range Radar Sensor Module Learn in the scantool. The driver information display will display "Service Driver Assist" message during calibration.
    NOTE:

    Do not back out of screen or press any other buttons until the calibration is complete.

  6. Drive the vehicle within the following conditions for 10-30 minutes or until calibration is complete. The "Service Driver Assist" message will turn off when calibration is complete.
    • Drive at speeds greater than 56 kph (35 mph)
    • Minimize tight curves
    • Avoid extreme acceleration or deceleration
    • Follow one or multiple vehicles. (typical vehicle traffic is sufficient, but vehicles 30m - 50m (100 -165ft) away are most effective at decreasing the calibration time)
    • Drive in an environment that has stationary objects on the side of the road (street signs, guard rails, mail boxes, fences, etc)
  7. Verify proper calibration by observing that the "Service Driver Assist" message turns off within 10-30 minutes of normal driving.
    • If "Service Driver Assist" message fails to turn off  
    1. Verify correct operating conditions were met
      • If incorrect driving environment, refer to If Slow to Calibrate and repeat calibration procedure following recommended operating conditions.
      • If correct driving environment
    2. Verify DTC B390C 66 Incorrect Mounting is not set
      • If B390C 66 is not set
    • If "Service Driver Assist" message turns off 
  8. Drive at speeds greater than 40 kph (25 mph) and verify engagement of Adaptive Cruise Control (cruise control icon will change from white to green)
    • If Adaptive Cruise Control will not engage 

      Check vehicle for DTCs and correct as required.

    • If Adaptive Cruise Control engages 
  9. All OK.
