DTC 36

Test V: DTC 36 Passenger Loop Energy Reserve Feed Open:

Supplemental Inflatable Restraint (SIR):

OPERATION:
During the "Continuous Monitoring" tests, the DERM monitors the voltage at "Passenger Source Sense" terminal "A6." When the circuit is operating normally, the measured voltage will be slightly less than "Passenger 36 VLR." If the "Passenger 36 VLR" circuit opens, the voltage measured at "Passenger Source Sense" will decrease to slightly less than "Ignition 1" voltage. When the voltage measured at "Passenger Source Sense" is within a specified range of "Ignition 1" for 500 milliseconds DTC 36 is set.

Test Conditions: Tested every 100 milliseconds during "Continuous Monitoring" tests.

Failure Conditions: DTC 36 will set when the voltage measured at "Passenger Source Sense" terminal "A6" is within a specified range of "Ignition 1" for 500 milliseconds.

Action Taken: DERM turns "ON" the "INFLATABLE RESTRAINT" warning lamp and sets a Diagnostic Trouble Code.

Conditions to Clear: DTC 36 will clear when the voltage measured at "Passenger Source Sense" terminal "A6" is outside the specified range of "Ignition 1" which sets the Diagnostic Trouble Code, for 500 milliseconds.

POSSIBLE CAUSES:
Test Description: Number(S) below refer to circled number(S) on the diagnostic chart.
1. This test checks for an open in the "Passenger 36 VLR" circuit.
2. This test determines whether the malfunction is due to high resistance in the "Passenger Source Sense" circuit.
3. This test checks for a short from the "Passenger Source Sense" circuit to B+.
4. This test determines whether the malfunction is due to a malfunction within the dual pole arming sensor.

DIAGNOSTIC AIDS:
An intermittent condition is likely to be caused by a poor connection at dual pole arming sensor terminal "C" to "F," poor connection at DERM terminal "A3" or "A6," an open in CKT 1401 or 1837, or an open inside the dual pole arming sensor.
