5-8840-2421-0 SRS Driver/Passenger Load
Tool
901RS146
The SRS Driver/Passenger Load Tool 5-8840-2421-0
is used only when called for in this section. It is used
as a diagnostic aid and safety device to prevent
inadvertent air bag assembly deployment.
The load tool has three yellow connectors attached to
its case.
The three small connectors are electrically functional
and serve as resistive load substitutions.
No more than two connectors are used at any time.
One of the small connectors is used to substitute for
the load of the driver air bag assembly when it is
connected at the top of the column to the SRS coil
assembly. Another small connector is used to
substitute for the load of the driver air bag assembly
and the SRS coil assembly when it is connected at the
base of the column to the SRS wiring harness. The
third small connector is used to substitute for the load
of the passenger air bag assembly when connected to
the passenger air bag assembly harness connector.
By substituting the resistance of the load tool when
called for, a determination can be made as to whether
an inflator circuit component is causing system
malfunction and which component is causing the
malfunction. The load tool should be used only when
specifically called for in the diagnostic procedures.
