Objectives To understand the function of Body Control Module. To understand the control function and operation condition. To understand the troubleshooting method.
The BCM supplies various conveniences for drivers and is applied to many vehicles. It is well familiar with us for many aspects including functional questions and malfunction examples. The BCM controls the body electrical system. New functions controlled by the BCM are, for example, the driver seat belt warning control, turn signal lamp control, head lamp control are supplemented. In addition, “User’s option” by which conveniences can be set to driver’s inclination items for easy checking using Hi-scan pro. Therefore, it will be possible to perform maintenances by more accurate diagnosis.

(2) Not dead lock but only central door lock is performed after central door lock output for 0.5s when all doors are locked by central door lock switch.
(3) Central door unlock signal is output for 0.5s after dead unlock is output for 0.5s and after 200ms when central door unlock switch is turned on by door key switch or transmitter after dead lock is output for 0.5s.
(4) Not dead unlock but only central door unlock is performed when central door unlock is turned on by central door lock switch. (The driver door is performed door unlock & dead unlock mechanically when the driver door is unlock by key.)
(5) Dead lock/unlock is performed when only door is closed. (But, exception is the state of dead lock by TX or door key. All doors unlock signal is output when door open by reminder function by TX or door key.)
(6) Lock function is performed first when both lock/ unlock functions are performed at the same Time.
(7) Priority is decided in order of TX> key > door lock switch in case of simultaneous input with Key / TX / door lock switch. If (7), (8) is happened simultaneously, priority is given to (8).
(8) Dead lock is canceled at ignition key is inserted in the key cylinder and ignition key is on position. (9) In the condition of IGN ON, dead lock is not output when door key switch is turned to lock. (10) Door lock/unlock signal output is ignored by central door lock / unlock switch during dead

After head lamp is turned off, headlamp signal output is kept if headlamp & tail lamp on luminance condition is met at auto light switch is turned on. After head lamp is turned off, head lamp signal output is immediately stopped if head lamp & tail lamp off luminance condition is met at auto light switch is turned on. After head lamp is turned off, head lamp signal output is immediately stopped at tail lamp switch signal input. After head lamp is turned off, head lamp signal output is stopped if there is no input of auto light switch or tail lamp switch. )Headlamp signal output is stopped when switch position is changed from auto to headlamp switch during head lamp on with auto light.
