Electric Tension Reducer System: Inspection
- INSPECT TENSION REDUCER SOLENOID OPERATION
- Connect the positive (+) lead from the battery to terminal 1, and negative (-) lead to terminal 2. (See Fig 1).
- Pull the belt upward and check that the belt is slowly retracted when released.
- Disconnect the lead from the battery.
- Pull the belt upward and check that the belt is retracted more quickly when released than in (b).
HINT:
Do not tilt the retractor.
If the operation is not as specified, replace the front seat outer belt assembly.
- INSPECT TENSION REDUCER SOLENOID CIRCUIT
Disconnect the tension reducer solenoid connector and inspect the connector on wire harness side, as shown.

TESTER CONNECTION SPECIFIED CONDITION (CONNECTOR DISCONNECTED)Tester connection Condition Specified condition 2 - Ground Buckle switch position OFF (belt unfastened) No continuity 2 - Ground Buckle switch position ON (belt fastened) Continuity 1 - Ground Ignition switch ACC or LOCK No voltage 1 - Ground Ignition switch ON Battery positive voltage If the circuit is specified, replace the front seat outer belt assembly.
If the circuit is not as specified, inspect the circuits connected to other parts.
- INSPECT SEAT BELT BUCKLE SWITCH CONTINUITY
- Check that continuity exists between the terminals 1 and 4 on the switch side connector with the switch ON (belt fastened). See Fig 4.
- Check that continuity exists between the terminals 2 and on the switch side connector with the switch OFF (belt unfastened). See Fig 4.
If operation is not as specified, replace the switch.
- INSPECT SEAT BELT BUCKLE SWITCH CIRCUIT
