1. Remove the B-pillar lower trim (see B-PILLAR UPPER/LOWER TRIM ).
2. Disconnect the 2P connector (A) from the seat belt tension reducer (B).

3. Measure the voltage between terminal No. 2 (+) and body ground with the ignition switch turned to ON (II). There should be battery voltage.
   • If there is no voltage, check for:
     • A blown No. 21 (10 A) fuse in the driver's under-dash fuse/relay box.
     • An open or high resistance in the YEL wire.
   • If there is battery voltage, go to step 4.
4. Turn the ignition switch to LOCK (0) and reconnect the 2P connector to the seat belt tension reducer.
5. Measure the voltage between terminal No. 1 and body ground with the ignition switch turned to 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.

6. Turn the ignition switch to LOCK (0).
7. Disconnect the 2P connector from the seat belt tension reducer.
8. Check for continuity between terminal No. 1 and body ground with the seat belt buckled.

There should be continuity.

• If there is no continuity, check for:
  • Poor ground (G601, G651*).
  • An open or high resistance in the wire.
  • Faulty seat belt buckle switch.
