HEIGHT ADJUSTABLE ANCHOR MOTOR AND SENSOR INSPECTION





1. INSPECT DRIVER'S MOTOR OPERATION
a. Connect the positive (+) lead from the battery to terminal 4 and the negative (-) lead to terminal 1. and check that the slider moves upward.
b. Reverse the polarity and check that the slider moves downward.
If operation is not as specified, replace the height adjustable anchor motor.

2. INSPECT PTC THERMISTOR OPERATION
Inspection using an ammeter:





a. Connect the positive (+) lead from the battery to terminal 1, the positive (+) lead from the ammeter to terminal 4, and the negative (-) lead to battery negative (-) terminal. then move the slider to end position.
b. Continue to apply voltage and check the current changes to less than 0.1 A within 6 to 46 seconds.
c. Disconnect the leads from terminals.





d. Approximately 60 seconds later, connect the positive (+) lead from battery to terminal 4 and the negative (-) lead to terminal 1, and check that the slider moves to the opposite side.
If operation is not as specified. replace the height adjustable anchor motor.

Inspection using an ammeter with a current-measuring probe:





a. Connect the positive (+) lead from the battery to terminal 1 and the negative (-) lead to terminal 4.
b. Attach a current-measuring probe to the negative (-) lead, and move the slider to the end position.
c. Check the current changes to less than 0.1 A with 6 to 46 seconds.
d. Disconnect the leads from terminals.





e. Approximately 60 seconds later, reverse the polarity, and check that the slider moves to the opposite side. If operation is not as specified, replace the height adjustable anchor motor.





3. INSPECT PASSENGER'S MOTOR OPERATION
a. Connect the positive (+) lead from the battery to terminal 2 and the negative (-) lead to terminal 1, and check that the slider moves upward.
b. Reverse the polarity and check that the slider moves downward.
If operation is not as specified. replace the height adjustable anchor motor.

4. INSPECT PTC THERMISTOR OPERATION
Inspection using an ammeter:





a. Connect the positive (+) lead from the battery to terminal 1, the positive (+) lead from the ammeter to terminal 2, and the negative (-) lead to battery negative (-) terminal. then move the slider to end position.
b. Continue to apply voltage and check the current changes to less than 0.1 A within 6 to 46 seconds.
c. Disconnect the leads from terminals.





d. Approximately 60 seconds later, connect the positive (+) lead from battery to terminal 2 and the negative (-) lead to terminal 1, and check that the slider moves to the opposite side.
If operation is not as specified. replace the height adjustable anchor motor.

Inspection using an ammeter with a current-measuring probe:

b. Attach a current-measuring probe to the negative (-) lead. and move the slider to the end position.
c. Check the current changes to less than 0.1 A within 6 to 46 seconds.
d. Disconnect the leads from terminals.





e. Approximately 60 seconds later. reverse the polarity and check that the slider moves to the opposite side. If operation is not as specified, replace the height adjustable anchor motor.
If circuit is not as specified, inspect wire harness.

SHOULDER BELT ADJUST SWITCH INSPECTION





1. INSPECT DRIVER'S SWITCH CIRCUIT





2. INSPECT DRIVER'S SWITCH CONTINUITY





3. INSPECT PASSENGER'S SWITCH CONTINUITY
If continuity is not as specified, replace the switch.








4. INSPECT PASSENGER'S SWITCH CIRCUIT
Disconnect the connector from the switch and inspect the connector on the wire harness side, as shown.
If circuit is not specified, inspect wire harness.

SHOULDER BELT ANCHOR RELAY INSPECTION

1. INSPECT RELAY OPERATION





Upward:
a. Connect the positive (+) lead from the battery to terminal 4 and the negative (-) lead to terminal 5 and 7.
b. Connect the positive (+) lead from the voltmeter to terminal 1 and negative (-) lead to battery negative (-) terminal, and check that there is battery positive voltage.





Downward:
a. Connect the positive (+) lead from the battery to terminal 4 and the negative (-) lead to terminal 7 and 8.
b. Connect the positive (+) lead from the voltmeter to terminal 3 and negative (-) lead to battery negative (-) terminal, and check that there is battery positive voltage.
If operation is not as specified, replace rheostat light control.








2. INSPECT RELAY CIRCUIT
Disconnect the connector from the rheostat light control and inspect the connector on the wire harness side, as shown.
If circuit is not as specified, inspect the circuits connected to other parts.
