SEAT CUSHION HEATER CHECK
Measure the resistance between terminals.
Standard value: At room temperature 20°C (68°F)
Between terminals 2 and terminal 3: Approximately 3.98 ohms +/- 5%
Between terminals 1 and terminal 3: 3.98 ohms +/- 5%
Note. When the interior temperature rises 1°C (34°F), a measurement standard value increases 0.031 ohms. And when the interior temperature drops 1°C (34°F), a measurement standard value decreases 0.031 ohms.

SEATBACK HEATER CHECK
Measure the resistance between terminals.
Standard value: At room temperature 20°C (68°F)
Approximately 4.51 ohms +/- 5%
Note. When the interior temperature rises 1°C (34°F), a measurement standard value increases 0.031 ohms. And when the interior temperature drops 1°C (34°F), a measurement standard value decreases 0.031 ohms.

- Disconnect the connector of each motor.
- Check that when the battery is directly connected to the motor terminal, the motor turns smoothly and each adjusting mechanism operates as stated below for each motor: Connect the battery power supply to the terminal 2 and ground the terminal 1, front slide side. Connect the battery power supply to the terminal 1 and ground the terminal 2, rear slide side. Connect the battery power supply to the terminal 3 and ground the terminal 2 for the front height down side and connect the battery power supply to the terminal 2 and ground the terminal 3 for the front height up side. Connect the battery power supply to the terminal 4 and ground the terminal 3 for the rear height up side and connect the battery power supply to the terminal 3 and ground the terminal 4 for the rear height down side.
- If abnormality was found, check the power seat adjuster assembly.
