TEST CONDITIONS
Tested every too milliseconds during "Continuous Monitoring."

FAILURE CONDITIONS
DTCs 19 and 23 set together when voltage at "Pass Side Low" and "Driver Side Low" inputs (E7 and B8) are greater than 50% of their respective "36VLR output (A3 or A4) for 500 milliseconds.

CONDITIONS TO CLEAR
Current DTCs 19 and 23 clear when voltage at "Pass Side Low" and "Driver Side Low" inputs (B7 and B8) are less than or equal to 50% of their respective "36VLR" output (A3 or A4) for 500 milliseconds.

ACTION TAKEN
DERM turns on "INFLATABLE RESTRAINT" warning lamp.

DESCRIPTION
DTCs 19 and 23 set together when failure conditions are met during DERM's "Continuous Monitoring" Tests. These tests are performed for one second after initial "Turn-on" Tests are completed, and every too milliseconds while "IGNITION 1" voltage is present at DERM (after "Initiator Circuit Resistance" Tests are completed). "Continuous Monitoring" Tests check both deployment loops for continuity from DERM's "36VLR" outputs through Dual Pole Arming Sensor, Inflator Modules, SIR Coil (driver's side only) and Discriminating Sensors to ground. DTCs 19 and 23 together indicate a shorted Dual Pole Arming Sensor 10200 ohm resistor, a short from either deployment loop to either "36VLR" circuit, a short from either deployment loop to either "Source Sense" circuit, or an open ground path through both Discriminating Sensors.

NOTES ON FAULT TREE
1. Checks for a short between "Driver Side High" and "Pass Source Sense" circuits.
2. Checks for a short between "Driver Side High" and "Driver Source Sense" circuits.
3. Checks for a short between "Driver Side High" and "Driver 36VLR" circuits.
4. Checks for a short between "Driver Side High" and "Passenger 36VLR" circuits.
5. Checks Dual Pole Arming Sensor for proper resistance. A shorted 10200 ohm resistor can cause DTCs 19 and 23 to set together.
