SEAT MOTOR
Disconnect power seat motor harness connector at each power seat motor. Apply battery voltage and ground between motor terminals. Reverse polarity to move seat in opposite direction. If power seat motor does not operate as described, replace power seat motor.
Remove heated seat switch. Check continuity between heated seat switch terminals with switch in specified position. (Scheme 9) See HEATED SEAT SWITCH CONTINUITY TEST (MILLENIA) table. If continuity is not as specified, replace seat heater switch.
| Switch Position | Check Continuity Between Terminals No. | |
|---|---|---|

| Off | H & G; B & D | |
| On | H, G & F; B & D | |
| Passenger's Seat Switch (2) | ||

| On | F, E & C; F & G | |
| (1) Terminals "H" and "G" are switch on indicator light circuit. Terminals "B" and "D" are switch illumination circuit. (2) Terminals "F" and "E" are switch on indicator light circuit. Terminals "B" and "D" are switch illumination circuit. | ||

HEATED SEAT SWITCH CONTINUITY TEST (MILLENIA)
Scheme 9
- Remove heated seat relay (located behind rear seat back). Check continuity between terminals "A" and "B" at heated seat relay. (Scheme 10) If continuity exists, go to next step. If continuity does not exist, replace heated seat relay.
- Check continuity between terminals "C" and "D" at heated seat relay. If continuity does not exist, go to next step. If continuity exists, replace heated seat relay.
- Apply positive battery voltage to terminal "A" and ground terminal "B" at heated seat relay. With voltage applied, check continuity between terminals "C" and "D" at heated seat relay. If continuity exists, relay is okay at this time. If continuity does not exist, replace heated seat relay.
