Memory Drivers Seat

Memory Drivers Seat

When the memory function is selected, the seat memory ECU (C0722) transmits the relevant data along the K-bus to the Body Control Unit (BCU) (C0660) on a WRY wire. The BCU then moves both the steering column and the door mirrors to the required position. For more information on door mirror operation, refer to the Door Mirrors section of this manual.  DOOR MIRRORS.

For more information on steering column operation, refer to the Steering Column section of this manual.  STEERING COLUMN.

Horizontal Movement

When the memory function is selected, the seat memory ECU (C0772) provides feeds to the forward/backward seat motor (C0720) on a pair of R wires. The seat memory ECU (C0772) monitors the position of the seat by measuring the voltage pulses returned from the hall effect sensor (C0720) on an R wire.

Vertical Movement

When the memory function is selected, the seat memory ECU (C0772) provides feeds to the front (C1637) and rear (C1636) up/down motors on R wires. The seat memory ECU (C0772) monitors the position of the seat by measuring the voltage pulses returned from the hall effect sensors (C1637 & C1636) on R wires.

Recline

When the memory function is selected, the seat memory ECU (C0772) provides feeds to the backrest recline seat motor (C0518) on a pair of R wires. The seat memory ECU (C0772) monitors the position of the seat by measuring the voltage pulses returned from the hall effect sensor (C0518) on an R wire.

Headrest

When the memory function is selected, the seat memory ECU (C0772) provides feeds to the headrest seat motor (C1419) on a pair of R wires. The seat memory ECU (C0772) monitors the position of the headrest by measuring the voltage pulses returned from the hall effect sensor (C1419) on an R wire.
