Turn the ignition switch to ON (II).
Make sure the HDS communicates with the vehicle and the SRS unit. If it does not communicate, inspect the power line of SRS unit, fuses, and ground, and if there is not any abnormality found, then troubleshoot the DLC circuit (see DLC CIRCUIT TROUBLESHOOTING ).
Use the HDS to check for SRS DTCs.
Read and record the DTC.
NOTE:
- Only read DTCs from the SRS menu, not from SWS menus unless instructed to check SWS DTCs. SWS (ODS unit) DTCs are subcodes of SRS unit DTCs. Only troubleshoot the corresponding SRS DTCs.
- Do not clear the DTC until instructed by the troubleshooting procedure.
Turn the ignition switch to LOCK (0), then wait for 10 seconds.
Disconnect the HDS from the DLC.
Do the troubleshooting procedure for the DTC.
