Seat Belt Anchor Position Is Not Memorized Or Does Not Move To Memorized Position





SEAT BELT: POWER SHOULDER BELT ANCHORAGE SYSTEM: Seat Belt Anchor Position is not Memorized or does not Move to Memorized Position
- Seat Belt Anchor Position is not Memorized or does not Move to Memorized Position

DESCRIPTION

The shoulder belt anchor has a built-in position detection sensor. When the front door ECU LH or front door ECU RH receives a seat memory switch signal, it sends a memory store signal or call signal to the front power seat switch LH or front power seat switch RH and luggage room junction block assembly (rear junction block ECU). When the luggage room junction block assembly (rear junction block ECU) receives the memory store signal, it uses the position detection sensor to memorize the current position of the shoulder belt anchor. When the luggage room junction block assembly (rear junction block ECU) receives the call signal, it uses memorized shoulder belt anchor position and the position detection sensor to perform the call operation.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK OPERATION OF SEAT MEMORY FUNCTION

(a) Check which seat memory function is not operating correctly.

OK:





B -- CHECK POWER BELT ANCHOR CONTROL FUNCTION
A -- Continue to next step.

2. CHECK POWER BELT ANCHOR CONTROL FUNCTION

(a) Operate the shoulder belt anchorage switch LH and check that the shoulder belt anchor LH operates normally.

Result





B -- GO TO DRIVER SIDE SEAT BELT ANCHOR DOES NOT OPERATE MANUALLY Driver Side Seat Belt Anchor Does Not Operate Manually
A -- Continue to next step.

3. CHECK SEAT MEMORY SWITCH FUNCTION (SHOULDER BELT ANCHOR MEMORY FUNCTION)

(a) Check that the seat belt anchor LH positions can be memorized using the seat memory switch.

OK:

Shoulder belt anchor LH positions can be memorized using seat memory switch.

NG -- GO TO POWER SEAT CONTROL SYSTEM Problem Symptoms Table
