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

INSPECTION PROCEDURE

PROCEDURE

1. CHECK POWER BELT ANCHOR CONTROL FUNCTION
(a) Operate the shoulder belt anchorage switch and check that the shoulder belt anchor RH operates normally.
Result:






B -- GO TO DRIVER SIDE SEAT BELT ANCHOR DOES NOT OPERATE MANUALLY
A -- Continue to next step.
2. 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
OK -- Continue to next step.
3. CHECK HARNESS AND CONNECTOR (REAR JUNCTION BLOCK ECU - SHOULDER BELT ANCHOR)





(a) Disconnect the S61 ECU connector.
(b) Disconnect the S7 anchor connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
4. CHECK SHOULDER BELT ANCHOR LH (BSE SIGNAL)





(a) Measure the resistance according to the value(s) in the table below.
Standard Voltage:






NG -- REPLACE SHOULDER BELT ANCHOR LH
OK -- REPLACE LUGGAGE ROOM JUNCTION BLOCK (REAR JUNCTION BLOCK ECU)
