2. FUNCTION OF MAIN COMPONENT
Component |
Function |
|
---|---|---|
Position control ECU and switch assembly |
Based on the switch operation, seat adjuster signals are input to the position control ECU and switch assembly to adjust the seat accordingly. |
|
Front seat frame with adjuster assembly LH |
Slide motor |
Receives a signal from the position control ECU and switch assembly, and slides the seat forward and rearward. |
Front vertical motor |
Receives a signal from the position control ECU and switch assembly, and raises and lowers the front of the seat cushion. |
|
Lifter motor |
Receives a signal from the position control ECU and switch assembly, and raises and lowers the seat cushion. |
|
Position sensor |
Built into each motor and sends position data to the position control ECU and switch assembly so that it can detect the position at all times. |
|
Reclining motor |
Receives a signal from the position control ECU and switch assembly, and tilts the seatback forward and rearward. |
|
Lumbar support adjuster assembly |
Receives a signal from the front lumbar power seat switch and operates the built-in motor to adjust the lumbar support. |
|
Seat memory switch |
If the seat memory SET switch is being pressed when one of the M1 or M2 seat memory switches is pressed, or if one of the M1 or M2 switches is pressed within 3 seconds of pressing the SET switch, the outer mirror control ECU assembly LH sends the signals so that the seat position can be stored. Then, when a seat memory switch is pressed, a signal is sent to the outer mirror control ECU assembly LH and the seat position changes according to memory. |
|
Front lumbar power seat switch |
Operates the motor built into lumbar support adjuster assembly according to switch operation. |

The seat memory switch sends memory switch information to the outer mirror control ECU assembly LH. Then the information is sent to the main body ECU (driver side junction block assembly) via CAN and then an instruction to memorize the seat position is sent to the position control ECU and switch assembly via CAN. As a result, the seat position is memorized.
Camshaft Position "B" Actuator Circuit / Open (Bank 1) (P0013)
DESCRIPTION
The Variable Valve Timing (VVT) system adjusts the exhaust valve timing to improve
driveability. The engine oil pressure turns the VVT controller to adjust the valve
timing.
The camshaft timing oil control valve is a solenoid valve and switch ...
