Driving position control unit M076 is supplied by two lines: one to pin B8 of connector C via service relay R21 and fuse F56 of boot junction unit B045 (used to supply the drive motors), the other to pin C7 of connector C via a line protected by fuse F69 of B045.The boot control unit is supplied by a line protected by fuse F61 of control unit B045. The front driver side control unit H066 is connected to connector B of driving position control unit M076 that supplies the various motors to determine their movements:
from pin A5 to pin C4 for forward sliding via motor N127 (from pins B1 and C1 of connector B) and for cushion tilt via front motor N126 (from pins A8 e B7 of connector B);
from pin B4 to pin B4 for backward sliding via motor N127 (from pins B1 and C1 of connector B, but with polarity reversed in relation to the forward sliding motion) and for cushion tilt via rear motor N125 (from pins A5 and C8 of connector B);
from pin B5 to pin A4 for backrest adjustment via motor N132 (from pins A1 and B5 of connector B);
from pins A3 and C3 for storage/recall of the three ride positions.
Simultaneous activation of both tilt motors N125 and N126 brings about lifting/lowering of the entire seat unit.Driving position control unit M076 maintains the three head restraint positions in the memory by means of a potentiometer that supplies its own analogue return signal:
to pin A3 of connector B from the potentiometer inside engine unit N126 (front cushion position);
to pin A2 of connector B from the potentiometer inside engine unit N125 (rear cushion position);
to pin B2 of connector B from backrest positioning potentiometer K131;
to pin C2 of connector B from seat longitudinal positioning potentiometer K130;
Memory store is indicated by a buzzer inside instrument panel E050 via a signal received on the B-CAN network at pins 3 and 4 of connector A.Absence of INT (Key-off) and driver side front door opening signals is detected by Body Computer M001 at pin 9 of connector H and pin 8 of connector F, and determines activation of the "Easy Entry Exit" described above.Service relay R21 is activated from a signal from boot control unit M063 (pin 24 of connector F), which enables (via the B-CAN network) movement of the various loads even during the timed period (one minute) following Key-off.Front passenger seat movements are determined by a different operating strategy. Control unit H067 governs operation of the various motors directly.
rear cushion tilt motor N128 from pins A6 and A7;
front cushion tilt motor N129 from pins A3 and A5;
backrest adjustment motor N135 from pins B4 and B5;
from pins A1 and A2 that supply the seat forward/backward slide motor N130 via remote control switches J105 and J106.
This forward/backward slide movement can also be controlled by the passenger side seat slide remote control switch on rear armrest H074 that, via earth signals and according to the required command, excites the coils of remote control switch J105 to control forward slide and J106 to control backward slide.Body Computer M001 receives a car speed signal from braking system control unit M051 at pin 7 of connector A: if this speed exceeds 10 Km/h, the Body Computer (pins 5 and 7 of H) inhibits any motion (automatic and/or manual) of the driver side seat via the B-CAN network. Driving position control unit M076 downloads this condition via the C-CAN network at pins A4 and B3 of connector C.Body Computer M001 receives an INT/A (key-on) signal from ignition switch H001 at pin 27 of connector D via fuse F31 of underfacia control unit B002.
