How to Read DTCs

  1. Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.
  2. Connect the HDS to the data link connector (DLC) (A).

  3. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.
  4. 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 go to the DLC circuit troubleshooting (see DLC CIRCUIT TROUBLESHOOTING ).
  5. Use the HDS to check for SRS DTCs.
  6. Read and record the DTCs.
    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. These SWS DTCs are cleared when you turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.
    • Do not clear the DTCs until instructed by the troubleshooting procedure.
  7. Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode, then wait for 10 seconds.
  8. Disconnect the HDS from the DLC.
  9. Do the troubleshooting procedure for the DTC.
