RH Pretens. Resist

The scan tool displays 0 - 6.6 ohms. The SDM performs the resistance measurement test once each ignition cycle and verifies the Ignition 1 and 23 VLR voltages are within the normal ranges. Then the SDM sources a constant current to the passenger seat belt pretensioner deployment loop. The SDM then measures the voltage drop across the deployment loop and converts the measured voltage value to a passenger seat belt pretensioner deployment loop resistance value.
