Without Scan Tool

All SRS DTCs are read using flash code diagnostics. Flash code diagnostics are enabled either by connecting a jumper wire between terminal "Tc" and terminal "E1" (ground) on the data link connector (DLC) with the ignition switch in "ACC" or "ON." Grounding terminal "Tc" of the DLC pulls the Diagnosis and Memory circuits terminal "B9," of the center sensor assembly low and signals the center sensor assembly to enter flash code diagnostic display mode.
