Seat Belt Retractor: Testing and Inspection
NOTE:
-
Perform this test on each seat belt retractor (2 per door).
-
The tips of test probes may need to be ground down to fit behind grommets in the connectors.
1. Remove the door trim panel.
2. Disconnect each 4-P connector from the seat belt retractor.
3. Connect the voltmeter positive probe to the WHT/GRN terminal and negative probe to the BLK terminal of each of the connector A and B. There
should be battery voltage.
-
If there is no voltage, check for:
-
Blown No.1 (10 A) fuse in the dash fuse box.
-
Poor ground (G201, 3301,3401)
-
An open in the BLK/YEL or BLK wire.
4. With the door open, check for continual click of the solenoid plunger whenever the each 4-P connector is alternately connected and
disconnected)Retractor solenoid test).
-
If it does not click, check for faulty latch switch and an open in the WHT/BLU (left door) or WHT/RED (right door) wire.
-
If they are OK, replace the seat belt assembly.
5. Connect all 4-P connectors.
6. Check for continuity between the GRN and GRN/BLU terminals of the connector B on the left door, or between the GRN and GRN/RED
terminals of the connector B on the right door when the door under test is opened and closed. There should be continuity when the door is closed
and no continuity when the door is opened.
-
If there is abnormality, replace the seat belt assembly.
7. Check for continuity between the GRN and BLK terminals of the connector A when the under test is opened and closed. There should be
continuity when the door is closed and no continuity when the door is opened.
-
If there is abnormality, replace the seat belt assembly.
8. Check for continuity between the GRN terminal of the connector A and GRN terminal of the connector B. There should be continuity.
-
If there is no continuity, repair open circuit in the GRN wire.
