DTC B1B89-13; Slide Motor And Position Sensor Circuit Malfunction: Notes

DETECTION CONDITION AND POSSIBLE CAUSES

Description	Slide motor and position sensor circuit malfunction
Detection condition	Position memory control module detects the following conditions during the slide motor operation control: Detects 4 times that current flowing to the slide motor is less than 1 A. Detects for 0.2 s that there is no change in the slide sensor pulse. Position memory control module detects 4 times that current flowing to the lift motor exceeds 1 A.
Fail-safe	Memory clearing: If there is a malfunction in the slide position sensor, clear all the memory positions. Memory seat positioning using position memory switch and remote transmitter: If there is a malfunction in the slide position sensor, inhibits all memory seat positioning. If there is a malfunction in the slide motor, inhibits slide motor seat positioning. Slide motor seat positioning using power seat switch: If there is a malfunction in the slide motor, inhibits slide motor seat positioning. Memory registration using position memory switch and remote transmitter: If there is a malfunction in the slide position sensor, inhibits the memory registration. If there is a malfunction in the slide motor and the malfunction is caused by short circuit, inhibits the memory registration.
Possible cause	Slide motor and position sensor connector or terminal malfunction Position memory control module connector or terminal malfunction Short to ground in wiring harness between the following terminals: Position memory control module terminal 3A-Slide motor and position sensor terminal D Position memory control module terminal 3B-Slide motor and position sensor terminal B Position memory control module terminal 3I-Slide motor and position sensor terminal F Position memory control module terminal 3J-Slide motor and position sensor terminal H Short to power supply in wiring harness between the following terminals: Position memory control module terminal 3A-Slide motor and position sensor terminal D Position memory control module terminal 3B-Slide motor and position sensor terminal B Position memory control module terminal 3I-Slide motor and position sensor terminal F Position memory control module terminal 3J-Slide motor and position sensor terminal H Open circuit in wiring harness between the following terminals: Position memory control module terminal 3A-Slide motor and position sensor terminal D Position memory control module terminal 3B-Slide motor and position sensor terminal B Position memory control module terminal 3I-Slide motor and position sensor terminal F Position memory control module terminal 3J-Slide motor and position sensor terminal H Front seat cushion frame/adjuster unit malfunction Slide motor and position sensor malfunction Position memory control module malfunction
