Is DTC displayed? Go to step 3. 40, Airbag Warn-
ing Light Fail-
ure.>Go to “Airbag
Wa r ni n g L ig h t Fa i l-
ure”.
3PERFORM DIAGNOSIS.
1) Judge the possible cause from “List of
Diagnostic Trouble Code” 45, List of Diagnostic Trouble Code (DTC).>.
2) Inspect the DTC using “List of Diagnostic
Tr o u b l e C o d e ( D T C ) ” .
3) Repair the trouble cause.
4) Perform the clear memory mode. AB(diag)-38, Clear Memory Mode.>
