DTC 82

Wiring Diagram:

CIRCUIT DESCRIPTION
During the "Turn-ON" tests, performed at the beginning of each ignition cycle, the DERM delays the charging of the "Driver 36 VLR" and "Passenger 36 VLR" power supplies. While the delay is active the DERM measures the voltage at the "Driver 36 VLR" terminal "A4," "Passenger 36 VLR" terminal "A3," "Driver Source Sense" terminal "A5," and "Passenger Source Sense" terminal "A6." When the voltage measured at the two "36 VLR" power supplies indicates they are in a discharged state, the voltage measured at "Driver Source Sense" is within a specified range of "Ignition 1" voltage and the voltage measured at "Passenger Source Sense" is a specified amount below "Ignition 1" voltage DTC 82 is set.

TEST CONDITIONS
Tested once each ignition cycle during the "Turn-ON" tests while the "36 VLR Delay" is active.

FAILURE CONDITIONS
DTC 82 will set when with both "36 VLR" power supplies in a discharged state, the DERM detects "Ignition 1" voltage at "Driver Source Sense" terminal "A5" while simultaneously the DERM does not detect "Ignition 1" voltage at "Passenger Source Sense" terminal "A6".

ACTION TAKEN
DERM turns "ON" the "AIR BAG" warning lamp and sets a diagnostic trouble code.

CONDITIONS TO CLEAR
DTC 82 will clear when, with both "36 VLR" power supplies in a discharged state, the "voltages measured at "Driver Source Sense" terminal "A5" and "Passenger Source Sense" terminal "A6" are simultaneously within a specified range of"Ignition 1" voltage. When neither the failure nor clear conditions are met, the state of the diagnostic trouble code from the previous ignition cycle is used.

TEST DESCRIPTION
Number(s) below refer to circled number(s) on the diagnostic chart.
1. This test checks for a short from the "Passenger Source Sense" circuit to the "Passenger 36 VLR" circuit.
2. This test check for a short from the "Passenger Source Sense" circuit to the "Driver 36 VLR" circuit.
3. This test determines whether the malfunction is due to an open within the dual pole arming sensor or a malfunctioning DERM.
