RESTRAINT CONTROL SYSTEM
DTC 46 Driver Pretensioner Loop Short To Voltage
D09RW014
Circuit Description:
When the ignition switch is turned “ON”, the SDM will
perform tests to diagnose critical malfunctions within
itself. Upon passing these tests, “Ignition 1”, and
pretensioner loop voltages are measured to ensure they
are within their respective normal voltage ranges.
The SDM monitors the voltage at “Driver Belt Low”
terminal “22” and “Passenger Belt Low” terminal “10” to
detect shorts to B+ in the pretensioner assembly circuits.
DTC Will Set When:
“Ignition 1” is in 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 Belt Low” is above a specified value,
DTC 46 will set.
Action Taken:
SDM turns “ON” the “AIR BAG” warning lamp and sets
DTC 46.
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
driver pretensioner assembly yellow 2–pin
connector at the base of the driver seat.
4. This test determines whether the malfunction is in
IB13–BLU/RED.
5. This test determines whether the malfunction is in
IB14–BLU/YEL.
Diagnostic Aids:
An intermittent condition is likely to be caused by a short
to B+ in the driver pretensioner assembly circuit. Inspect
IB13–BLU/RED and IB14–BLU/YEL carefully for cutting
or chafing. If the wiring pigtail of the driver pretensioner
assembly is damaged, the components must be
replaced. A careful inspection of IB13–BLU/RED and
IB14–BLU/YEL, including the driver pretensioner
assembly is essential to ensure that the replacement
SDM will not be damaged.
