5–8840–2421–0 (J–41433) SRS Driver/
Passenger Load Tool
The Supplemental Restraint System (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 four 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.

5–8840–0285–0 (J–39200) DVM
The 5–8840–0285–0 Digital Multimeter (DVM) is the
preferred DVM for use in SRS diagnosis and repair.
However, 5–8840–0366–0 may be used if 5–8840–
0285–0 is not available. No other DVMs are approved
for SRS diagnosis and repair.
