DTC 17

��XDiagnostic Chart:

Wiring Diagram:

CIRCUIT DESCRIPTION
When there is an open in the passenger inflator module jumper or the passenger inflator module the resistance between "Passenger Side High" terminal "A7" and "Passenger Side Low" terminal "B7" increases. This causes a larger voltage drop from the "Passenger Side High" to the "Passenger Side Low" across a resistor inside the DERM which connects these two terminals together. The increase in the voltage difference between "Passenger Side High" and "Passenger Side Low" is detected by the DERM during the "Continuous Monitoring" tests and DTC 17 is set.

TEST CONDITIONS
Tested every 100 milliseconds during the "Continuous Monitoring" tests.

FAILURE CONDITIONS
DTC 17 will set when the voltage difference between "Passenger Side High" terminal "A7"and "Passenger Side Low" terminal "B7" is above or equal to a specified value for 500 milliseconds.

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

CONDITIONS TO CLEAR
DTC 17 will clear when the voltage difference between "Passenger Side High" terminal "A7" and "Passenger Side Low" terminal "B7" is below a specified value for 500 milliseconds.

TEST DESCRIPTION
Number(s) below refer to circled number(s) on the diagnostic chart.
1. This test checks whether the DERM has set the diagnostic trouble code falsely.
2. This test determines whether the malfunction is in the passenger inflator module or the passenger inflator module jumper.
