Seat Belt Tension Reducer: Test

Remove the B-pillar lower trim (see TRIM REMOVAL/INSTALLATION - DOOR AREAS ).
Disconnect the 2P connector (A) from the seat belt tension reducer (B).

Fig 1: Identifying 2P Connector From Seat Belt Tension Reducer
Check for voltage between the No. 1 (+) terminal and body ground with the ignition switch ON (II). There should be battery voltage.
- If there is no voltage, check for:
  - A blown No. 21 (7.5 A) fuse in the under-dash fuse/relay box.
  - An open in the YEL wire.
- If there is battery voltage, go to step 4.
Turn the ignition switch OFF, and reconnect the 2P connector to the seat belt tension reducer.
Check for voltage between the No. 2 terminal and body ground with the ignition switch ON (II) and the seat belt unbuckled.
There should be battery voltage.
- If there is no voltage, check for a faulty seat belt switch, short to body ground on the LT GRN (or ORN) wire, or replace the seat belt tension reducer.
- If there is battery voltage, go to step 6.
Turn the ignition switch OFF.
Disconnect the 2P connector from the seat belt tension reducer.
Check for continuity between the No. 2 terminal and body ground with the seat belt buckled. There should be continuity.
- If there is no continuity, check for:
  - Poor ground (G 503, G601, G602).
  - An open in the wire.
  - Faulty seat belt buckle switch.
