Positioned at the rear of the vehicle, the rear body control module (RBCM) performs numerous system controls for functions at the vehicle rear.
Control table
The rear body control module (RBCM) controls the system based on the input/output signals.
The functions which are controlled are as follows:
| Control | Content | Reference |
| Interior light control system control | The rear body control module (RBCM) changes the illumination condition and illumination level of the interior light (door position) according to whether the doors are opened/closed. | (See INTERIOR LIGHTING SYSTEM.) |
| Back-up light control | The back-up light illuminates in conjunction with the shift operation. | (See REAR COMBINATION LIGHT.) |
| Power door lock system control | A power door lock system has been adopted in which all doors and the liftgate are locked/unlocked when the driver's door is locked/unlocked using the driver's door lock knob, or the door key cylinder is operated. | (See POWER DOOR LOCK SYSTEM.) |
| Trunk lid opener system control | A trunk lid opener system has been adopted in which the trunk lid can be opened just by pressing the trunk lid opener switch. | (See TRUNK LID OPENER SYSTEM.) |
| CAN (Controller Area Network) | Sends and receives signals between CAN system-related modules using the CAN system. | |
| ON-BOARD DIAGNOSTIC SYSTEM | The rear body control module (RBCM) is equipped with an on-board diagnosis function which records DTCs in the event of a malfunction. | (See ON-BOARD DIAGNOSTIC SYSTEM [REAR BODY CONTROL MODULE (RBCM)].) |
Power window system, Auto dimming mirror
Power door lock system, theft-deterrent system
Room lights, brake light system
Fuel-level sensor system
CAN system
If an error is detected in a combination of the door lock-link switch signals, the rear body control module (RBCM) controls the interior light based on the signal before the error occurred.
If the CAN signal cannot be received normally, the rear body control module (RBCM) controls the interior light based on the signal last received. If the CAN signal cannot be received normally for 5 s or more, the rear body control module (RBCM) stops the interior light control.
