Turn the ignition switch to ON (II).
Make sure the HDS communicates with the PCM and other vehicle systems. If it doesn't, troubleshoot the DLC circuit.
Check for diagnostic trouble codes (DTC) and note them. Also check the freeze data and/or on-board snapshot data, and download any data found.
Refer to the indicated DTC's troubleshooting, and begin the appropriate troubleshooting procedure.
NOTE:
- After troubleshooting, clear the DTCs with the HDS.
- For specific operations, refer to the user's manual that came with the HDS.
