 Install the protrusion (A) of the bracket into the locating hole (B) of
the accelerator pedal assembly before tightening the accelerator
pedal assembly mounting bolts.
InspectionINFOID:0000000003793274
INSPECTION AFTER INSTALLATION
 Check accelerator pedal moves smoothly within the whole operation range when it is fully depressed and
released.
 Check accelerator pedal securely returns to the fully released position.
 For the electrical inspection of accelerator pedal position sensor, refer to EC-306, "
Component Inspection",
EC-309, "
Component Inspection" and EC-316, "Component Inspection".
-CAUTION:
When harness connector of accelerator pedal position sensor is disconnected, perform “Accelerator
Pedal Released Position Learning”. Refer to EC-15, "
ACCELERATOR PEDAL RELEASED POSITION
LEARNING : Special Repair Requirement".

Order Input Output Control unit condition
1 Memory switch —The memory switch signal is inputted to the driver seat control unit
when memory switch 1 or 2 is operated
2—Motors
(Seat)Driver seat control unit operates each motor of seat when it recogniz-
es the memory switch has been pressed for 0.5 seconds or more and
requests each motor operation
Memory switch Indica-
torDriver seat control unit requests the blinking of memory indicator
while either of the motors are operating. The driver seat control unit
illuminates the memory indicator
3Sensors
(Seat)—Driver seat control unit judges the operating seat position with each
seat sensor input. Driver seat control unit stops the operation of each
motor when each part reaches the recorded address
4—Memory switch Indica-
torDriver seat control unit requests the illumination of memory indicator
after all motors stop. The driver seat control unit illuminates the mem-
ory indicator for 5 seconds
