RESTRAINT CONTROL SYSTEM
DTC 19 Passenger Deployment Loop Short To Voltage
D09RX002
Circuit Description:
When the ignition switch is turned “ON", the Sensing
and Diagnostic Module (SDM) will perform tests to
diagnose critical malfunctions within itself. Upon
passing these tests, “ignition 1", and deployment loop
voltages are measured to ensure they are within their
respective normal voltage ranges.
The SDM monitors the voltages at “Driver Bag Low"
terminal “4" and “Passenger Bag Low" terminal “16" to
detect short to B+ in the air bag assembly circuits.
DTC Will Set When:
“Ignition 1" is within the normal operating voltage range.
Once these conditions are met and the voltage at
“Passenger Bag Low" is above a specified value,
Diagnostic Trouble Code (DTC) 19 will set. This test is
run once each ignition cycle and “Continuous
Monitoring".
Action Taken:
SDM turns “ON" the “AIR BAG" warning lamp and sets
DTC 19 and also DTC 71.
DTC Will Clear When:
The SDM is replaced.
DTC Chart Test Description:
Number(s) below refer to step number(s) on the
diagnostic chart:
2. This test determines whether the malfunction is in the
SDM.
3. This test isolates the malfunction to one side of the
passenger air bag assembly yellow 2–pin connector
behind glove box compartment.
4. This test determines whether the malfunction is in
Circuit(CKT) IB07–YELLOW/GREEN.
