SEAT: FRONT POWER SEAT CONTROL SYSTEM: ON-VEHICLE INSPECTION

1. MANUAL OPERATION CHECK

(a) Check that the power seat operates whenever the front power seat switches (slide, front vertical, lifter, reclining, lumbar support) are operated.

2. MEMORY AND REPRODUCTION OPERATION CHECK

(a) Check the memory and reproduction operation.

HINT
If the M1 switch and M2 switch are simultaneously pressed while the SET switch is pressed and held, the memory will not be stored.

(1) Turn the ignition switch to ON.

(2) Move the seat into the foremost and uppermost positions via the seat switch.

(3) Check that the buzzer sounds for 0.5 seconds and the seat position is memorized when the M1 switch of the memory switch and SET switch are pressed and held, or the SET switch is pressed and then the M1 switch is pressed within 3 seconds.

(4) Move the seat out of the foremost and uppermost positions via the seat switch.

(5) Check that the buzzer sounds for 0.5 seconds and the seat position is memorized when the M2 switch of the memory switch and SET switch are pressed and held, or the SET switch is pressed and then the M2 switch is pressed within 3 seconds.

(6) Turn the ignition switch to ON and move the shift lever to P. Or, when the vehicle speed is 5 km/h (3 mph) or less with the ignition switch ON, move the shift lever to N.

(7) Check that the buzzer sounds for 0.1 seconds and the seat automatically moves into the foremost and uppermost positions (memorized positions) when the M1 switch of the memory switch is pressed for 1 second.

(8) Check that the buzzer sounds for 0.1 seconds and the seat automatically moves out of the foremost and uppermost positions (memorized positions) when the M2 switch of the memory switch is pressed for 1 second.

(9) Turn the ignition switch off, and then press either memory switch M1 or M2 within approximately 180 seconds after a door is opened, or within approximately 60 seconds after the driver door is closed. Check that a buzzer sounds for 0.1 seconds and the seat moves to the memorized position.

(b) Clear the memory.

(1) Turn the ignition switch to ON.

(2) Press the front power seat switch (front vertical switch) downward 3 times.

HINT
Perform each switch operation within 10 seconds of the previous operation.

(3) Within 10 seconds of the above operation, begin the following operation: perform the rearward reclining operation and upward lifter operation simultaneously for 10 seconds or more (a buzzer sounds for 0.5 seconds). This will clear the memory and cancel the initialization.
