RESTRAINT CONTROL SYSTEM
9J1–37
DTC 24 Driver Deployment Loop Short To Ground
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 voltage at “Driver Bag Low"
terminal “4" and “Passenger Bag Low" terminal “16" to
detect shorts to ground in the air bag assembly circuits.
DTC Will Set When:
Neither of the two air bag assemblies is open.
“Ignition 1" is within the normal operating voltage range.
This test is run once each ignition cycle and
“Continuous Monitoring". Once these conditions are
met and the voltage at “Driver Bag Low" is below a
specified value, DTC 24 will set.
Action Taken:
SDM turns “ON" the “AIR BAG" warning lamp and sets
a diagnostic trouble code.
DTC Will Clear When:
The malfunction is no longer occurring and the ignition
is turned “OFF."
DTC Chart Test Description:
Number(s) below refer to step number(s) on the
diagnostic chart:
2. This test determines whether the SDM is
malfunctioning
3. This test isolates the malfunction to one side of the
Supplemental Restraint System (SRS) coil assembly
yellow 2–pin connector at the base of the steering
column.
