SRS CONTROL SYSTEM 9C-59
5-8840-2421-0 SRS substitute load
This tool is used for diagnostic aid and for safety device
to prevent unnecessary SRS airbag deployment.
Three yellow connectors are provided to the SRS sub-
stitute load case.
These small three connectors work as substitute for re-
sistance load device electrically.
One of the small connector substitutes the load of SRS
coil assembly by connecting to the SRS coil assembly
located in the upper portion of steering column. Another
small connector substitutes the load of driver’s airbag
assembly by connecting to the SRS harness connector
located in the lower portion of steering column.
Use of substitute load in place of inflator circuit resis-
tance when necessary enables to judge if the parts in
the inflator circuit cause the system function fault, and
also enables to detect which part causes the function
fault.
Substitute load must be used only when it is necessary
in the diagnostic procedure.
5-8840-0385-0 Connector test adapter kit
Connector test adapter kit is necessary whenever termi-
nal inspection or detail inspection is requested in the di-
agnostic procedure. Use appropriate adapter to prevent
terminals from damage such as bending by DMM probe.
It is also useful to find poor contact caused by insuffi-
cient pressure by checking if sufficient pressure is ap-
plied to the terminal.
