  7. AM7 CHECK THE ABS MODULE ROLL RATE (ROLL_RATE) PID

    • Read and record the ROLL_RATE PID with the vehicle on level ground and at a complete standstill.
    • Monitor the ROLL_RATE PID while rocking and shaking the vehicle.

    Is the ROLL_RATE PID value between -0.05 and 0.05 with the vehicle at a standstill and does the PID fluctuate when the vehicle is moved? 

    Yes  For vehicles equipped  with active park assist, GO to  AM9. For vehicles not equipped  with active park assist, GO to  AM10.
    No  GO to  AM8.

  8. AM8 CHECK THE RCM INSTALLATION AND MOUNTING SURFACE
