ground the terminal 2 for the rear reclining side, front 
slide side.

(2) Connect the battery power supply to the terminal 2 and 

ground the terminal 1 for the front reclining side, rear 
slide side.

(3) Connect the battery power supply to the terminal 2 and 

ground the terminal 3 for the front height down side and 
connect the battery power supply to the terminal 3 and 
ground the terminal 2 for the front height up side.

(4) Connect the battery power supply to the terminal 3 and 

ground the terminal 4 for the rear height up side and 
connect the battery power supply to the terminal 4 and 
ground the terminal 3 for the rear height down side.

3. If abnormality was found, check the power seat adjuster
