| Passenger door ajar status | Body Control Module (BCM) | The Anti-Lock Brake System (ABS) module resets the parameters used for the Roll Stability Control (RSC) function when the passenger door is opened. |
| Passenger rear door ajar status | Body Control Module (BCM) | The Anti-Lock Brake System (ABS) module resets the parameters used for the Roll Stability Control (RSC) function when the passenger rear door is opened. |
| Restraints Control Module (RCM) serial number | Restraints Control Module (RCM) | The Anti-Lock Brake System (ABS) module stores the Restraints Control Module (RCM) serial number and verifies the serial number when the vehicle is started or the ignition is set to run or accessory. Over time, the Anti-Lock Brake System (ABS) module learns the offset of the sensors inside the Restraints Control Module (RCM). When a new serial number is found, the Anti-Lock Brake System (ABS) module resets the offset number learned for Roll Stability Control (RSC). |
| Selector lever (PRNDL) status | Powertrain Control Module (PCM) | This message provides the Anti-Lock Brake System (ABS) module with the current transaxle gear status. The Electronic Stability Control (ESC) and Roll Stability Control (RSC) functions do not operate when the transaxle is in REVERSE. |
| Steering angle calibration | Power Steering Control Module (PSCM) (vehicles without active park assist) | This message indicates at what angle the steering wheel is turned. |
| Steering angle calibration | Steering Column Control Module (SCCM) (vehicles with active part assist) | This message indicates at what angle the steering wheel is turned. |
| Steering angle count | Power Steering Control Module (PSCM) (vehicles without active park assist) | The Anti-Lock Brake System (ABS) module uses this message to determine the validity of the steering angle sensor signal. |
| Steering angle count | Steering Column Control Module (SCCM) (vehicles with active part assist) | The Anti-Lock Brake System (ABS) module uses this message to determine the validity of the steering angle sensor signal. |
