Conditions for Clearing the DTC
* The condition for setting the DTC no longer exists.
* A history DTC will clear once 100 malfunction-free ignition cycles have occurred.
Diagnostic Aids
Inspect the passenger seat belt tension sensor signal, voltage reference, and low reference circuits carefully for cutting and/or chafing.

Circuit/System Testing
Important: The seat belt buckle replacement with the seat belt tension sensor must be serviced as a complete unit.
When removing connectors, inspect for damage or corrosion. Damage or corrosion in the following requires repair or replacement of the
affected component/connector:
* Seat belt tension sensor
* PPS module
* Seat belt tension sensor wiring harness connector
* PPS module wiring harness connector
1. Ignition OFF, disconnect the harness connector at the passenger seat belt tension sensor and inspect the component and harness sides for
damage or corrosion.
锟斤拷 If damage or corrosion is found, repair or replace as necessary.
2. Ignition ON, test for 4.5-5.5 volts between the passenger seat belt tension sensor voltage reference circuit terminal A X2 and ground.
锟斤拷 If less that the specified range, test the voltage reference circuit for open/high resistance or a short to ground. If the circuit tests normal,
replace the PPS module.
锟斤拷 If greater that the specified range, test the voltage reference circuit for a short to voltage. If the circuit tests normal, replace the PPS
module.
3. Ignition OFF, remove the AIR BAG BATT Fuse in the underhood fuse block. Test for less than 2.0 ohms between the passenger seat belt
tension sensor low reference terminal B X2 and ground.
锟斤拷 If greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the PPS
module.
4. Ignition OFF, disconnect the harness connector at the PPS module.
5. Ignition ON, test for infinite resistance between the passenger seat belt tension sensor signal circuit terminal C X2 and ground.
