The OBD (on-board diagnostic) system has the following functions:
Malfunction detection function: Detects malfunctions in the air bag
system and outputs DTCs.
PID/data monitor function: Reads out specific input/output signals and
the system status.
Diagnostic DTCs can be read/cleared using the M-MDS.
NOTE:
Use the M-MDS to verify DTCs because the DTCs displayed by the air
bag system warning light are reference information only.
FLOWCHART
Use the following flowchart to verify the cause of the trouble.
NOTE:
When inspecting past malfunction codes, inspect only the DTCs that were
indicated before beginning the
inspection. A mis-diagnosis could occur as a result of new DTCs being added
while performing an inspection
by disconnecting related parts or connectors.
When DTCs of the present malfunction are no longer output after present
or past malfunctions or both have
been repaired, be sure to clear the past malfunction from memory to prevent
repair of malfunctions that
have already been repaired.
