DRIVER INITIATOR CIRCUIT OPEN
CIRCUIT DESCRIPTION
When there is an open in the driver inflator module or the
SRS coil assembly the resistance between "Driver Side
High" terminal "89" and "Driver Side Low" terminal "88"
increases. This causes a larger voltage drop from the
"Driver
Side High" to the "Driver Side Low" across a
resistor inside the DERM which connects these two
terminals together. The increase in the voltage difference
between "Driver
Side High" and "Driver Side Low" is
detected by the DERM during the "Continuous
Monitoring" tests and DTC 26 is sets.
DTC WILL SET WHEN
The voltage difference between "Driver Side High"
terminal "89" and "Driver Side Low" terminal "88" 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.
TO IGNITION FUSE SRS C-23 lOA , ...
DTC WILL TEST WHEN
The voltage difference between "Driver Side High"
terminal "89" and "Driver Side Low" terminal "88" is
below a specified value for 500 milliseconds.
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 driver inflator module.
3. This test determines whether the malfunction is in
the SRS coil assembly.
4. This test determines whether the malfunction is in
the SRS HARNESS.
DIAGNOSTIC AIDS
This diagnostic trouble code will only set when there is
an improper connection of either the
yellow 2-way
connector near the base of steering column or the yellow
2-way connector at the top of the steering column, an
open SRS coil assembly or an open inflator module.
