TEST CONDITION
Tested every 100 milliseconds during "Continuous Monitoring."

FAILURE CONDITIONS
DTC 24 sets when the voltage at the Sense Low input (terminal A6) is between 0% and 41% of 36VLR output voltage for 500 milliseconds.

CONDITIONS TO CLEAR
DTC 24 clears when the voltage at the Sense Low input (terminal A6) is between 41% and 61% of 36VLR output voltage for 500 milliseconds.

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

DESCRIPTION
DTC 24 is set when the voltage at the Sense Low input (terminal A6) is between 0% and 41% of 36VLR output voltage for 500 milliseconds during the DERM's "Continuous Monitoring" tests. The "Continuous Monitoring" tests are performed by the DERM after the initial "Turn-on" tests are completed and are performed every 100 milliseconds while "IGNITION 1" voltage is present at the DERM. The "Continuous Monitoring" tests check the deployment loop's continuity from the DERM's 36VLR output through the Arming Sensor, Inflator Module and the Discriminating Sensors to ground. DTC 24 sets when the Arming Sensor resistance is too high or open; the Discriminating Sensor resistance is too low or shorted; the Force Hi, Sense Hi, Sense Low or Force Low circuits are shorted to ground or system voltage; or the deployment loop's high side is shorted to the low side.

NOTES ON FAULT TREE
1. Checks for short to ground in circuit 347.
2. Checks for a short to ground in Force Hi circuit.
3. Checks for a short to ground in Sense Hi circuit.
4. Checks for a short to ground in Sense Low circuit.
5. Checks for short to ground in Force Low circuit.
6. Checks for a short to ground in circuit 349.
