DTC 14

Test E: DTC 14 Dual Pole Arming Sensor Disconnected:

Supplemental Inflatable Restraint (SIR):

OPERATION:
The DERM monitors the voltage at the "Driver Source Sense" terminal A5", the "Passenger Source Sense" terminal "A6", the "Driver Side High" terminal "B9", the "Passenger Side High" terminal "A7", the "Driver Side Low" terminal "B8" and the "Passenger Side Low" terminal "B7" during the "Continuous Monitoring" tests. When all voltages are simultaneously below a specified value for 500 milliseconds DTC 14 sets.

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

Failure Conditions: DTC 14 will set when the voltages at terminals "A5", "A6", "B9", "A7", "B8" and "B7" of the DERM Harness Connector are simultaneously below a specified value for 500 milliseconds.

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

Conditions to Clear: DTC 14 will clear when the voltage at terminals "A5", "A6", "B9", "A7", "B8" or "B7" of DERM Harness Connector is above specified value for 500 milliseconds.

POSSIBLE CAUSES:
Test Description: Number(S) below refer to circled number(S) on the diagnostic chart.
1. This test checks for a situation which prevents a proper connection of the Dual Pole Arming Sensor to the SIR wiring harness.


DIAGNOSTIC AIDS:
It is highly unlikely that an intermittent condition has set this DTC as this would require a poor connection at terminals "A", "B" and "C" or at terminals "D", "E", "F" and "G."
