    HINT:
    
    The seat vibrator operation and air operation are separate and independent of each other. When the air operation is OFF, the seat vibrator can be turned ON with the VIB. switch, but cannot be turned OFF with the VIB. switch. When the air operation is ON, the seat vibrator can be turned ON and OFF with the VIB. switch.
  4. Check that the vibration speed can be switched between 7 levels with the VIB. SPEED switch.
    HINT:
    
    When the VIB. switch is turned ON, the initial vibration speed is level 4 (LEDs 15 to 18 illuminated).
Inspect PROGRAM function
1. Turn the engine switch on (ACC or IG) (stop mode).
2. Turn the seat vibrator switch ON (standby mode).

3. When the SHIATSU switch is pressed, check that the shoulder and lower back areas operate in combination with each other.
4. When the STRETCH switch is pressed, check that the shoulder and lower back areas operate in combination with each other.
5. Check that the INTENSITY switch has 3 levels (low to high) and the SPEED switch has 3 levels (slow to fast).
Inspect LED illumination
1. Turn the engine switch on (ACC or IG).
2. Turn the seat vibrator switch ON.
3. Check that when each seat vibrator switch is pressed, its respective LED illuminates.
4. Check that when the headlight dimmer switch is turned on, each LED dims.

Inspect timer function
1. Turn the engine switch on (ACC or IG).
2. Turn the seat vibrator switch ON.
3. Choose a function on the seat vibrator switch and start its operation.
  HINT:
  
  The 15 minute timer counts down from the time that the function is first operated.
4. After 15 minutes have passed, check that the following operations occur.
  - The seat vibrator switch turns OFF.
  - All LEDs turn off.
  - The air operation stops after releasing the air.

Perform ACTIVE TEST

Rear Seatback Mat

While pressing the SW1 to SW4 switches on the seat vibrator switch, turn the engine switch on (ACC or IG).
HINT:

Before pressing a seat vibrator switch, turn the engine switch off.
Within 3 seconds of releasing the SW1 to SW4 switches, press the VIB. switch (SW10) 3 times.
HINT:
- It is necessary to begin pressing the VIB. switch immediately after turning the engine switch on (ACC or IG).
- If the procedure cannot be performed within 3 seconds, start again from the first step.
