Scan Tool Data Definitions. Opel Sintra 1999

For 1990-2009 cars

The SIR scan tool data definitions contain a brief description of all SIR related parameters available on the scan tool. The parameters that are available on the scan tool are listed below in alphabetical order.

Driver Frontal 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 the 23 VLR voltages are within the normal ranges. Then the SDM sources a constant current to the driver deployment loop. The SDM then measures the voltage drop across the deployment loop and converts the measured voltage value to a driver deployment loop resistance value.
Driver Frontal Senselo: The scan tool displays 0-20 volts. The SDM measures the voltage at the driver frontal low terminal 2 and displays this value as Driver Frontal Senselo.
Driver Frontal VDIF: The scan tool displays 0-500 millivolts. The SDM measures the voltage difference between driver frontal high and driver frontal low and displays this voltage difference as Driver VDIF.
Driver Seatbelt: The scan tool displays Buckled or Unbuckled. The SDM determines this by looking at whether the driver seat belt is buckled or unbuckled.
Ignition: The scan tool displays the battery voltage. The ignition represents the system voltage that is measured by the SDM between terminal 5 and terminal 7.
LH 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 driver seat belt pretensioner deployment loop. The SDM then measures the voltage drop across the deployment loop and converts the measured voltage value to a driver seat belt pretensioner deployment loop resistance value.
LH Pretens. Senselo: The scan tool displays 0-20 volts. The SDM measures the voltage at the driver seat belt pretensioner low terminal 9 and displays this value as LH Pretens. Senselo.
LH Pretensioner VDIF: The scan tool displays 0-500 millivolts. The SDM measures the voltage difference between driver belt high and driver belt low and displays this voltage difference as LH Pretensioner VDIF.
LH Side Air Bag 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 LH side air bag deployment loop. The SDM then measures the voltage drop across the deployment loop and converts the measured voltage value to a LH side air bag deployment loop resistance value.
LH Side Air Bag Senselo: The scan tool displays 0-20 volts. The SDM measures the voltage at the LH side air bag low terminal 10 and displays this value as LH Side Air Bag Senselo.
LH Side Air Bag VDIF: The scan tool displays 0-500 millivolts. The SDM measures the voltage difference between driver side high and driver side low and displays this voltage difference as LH Side Air Bag VDIF.
Pass. Frontal 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 deployment loop. The SDM then measures the voltage drop across the deployment loop and converts the measured voltage value to a passenger deployment loop resistance value.
Pass. Frontal Senselo: The scan tool displays 0-20 volts. The SDM measures the voltage at the passenger frontal low terminal 3 and displays this valus as Passenger Frontal Senselo.
Passenger Frontal VDIF: The scan tool displays 0-500 millivolts. The SDM measures the voltage difference between passenger frontal high and passenger frontal low and displays this voltage difference as Passenger VDIF.
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.
RH Pretens. Senselo: The scan tool displays 0-20 volts. The SDM measures the voltage at the passenger seat belt pretensioner low terminal 15 and displays this value as RH Pretens. Senselo.
RH Pretensioner VDIF: The scan tool displays 0-500 millivolts. The SDM measures the voltage difference between passenger belt high and passenger belt low and displays this voltage difference as RH Pretensioner VDIF.
RH Side Air Bag 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 RH side air bag deployment loop. The SDM then measures the voltage drop across the deployment loop and converts the measured voltage value to a RH side air bag deployment loop resistance value.
RH Side Air Bag Senselo: The scan tool displays 0-20 volts. The SDM measures the voltage at the RH side air bag low terminal 14 and displays this value as RH Side Air Bag Senselo.
RH Side Air Bag VDIF: The scan tool displays 0-500 millivolts. The SDM measures the voltage difference between passenger side high and passenger side low and displays this voltage difference as RH Side Air Bag VDIF.
Warning Lamp ON: The scan tool displays 0-182 hours. The SDM measures the continuous warning lamp ON time.
Warning Lamp Cycles: The scan tool displays 0-125 cycles. The ignition cycles of the current warning lamp state.
