Signal Circuit Inspection
- Connect Belt tension sensor connector & PODS ECU.
- Ignition "ON" & Engine "OFF".
- When mounting seat belt, check belt tension signals for change for various belt tension.
- Measure voltage between terminal 3 of the Belt tension sensor connector and chassis ground.
Specification : approx. 0.98V (Min) ~ 3.963V (Max)
- Is the measured voltage within specification?
YES
- Check Belt tension sensor for contamination, deterioration, or damage. Substitute with a known-good Belt tension sensor and check for proper operation. If the problem is corrected, replace Belt tension sensor and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NO
- Substitute a known-good Belt tension sensor, and check for proper operation.
If the problem is corrected, replace the Belt tension sensor and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
- Substitute a known-good PODS ECU, and check for proper operation.
If the problem is corrected, replace the PODS ECU and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
