      • Many of the options (PIDs) you see are the options that are available that will help us diagnose any issues you may be having with your truck.
  • To Verify DSP5 Voltage
    • Scroll down to “DSP5 Vol”. (as you switch your tunes, this voltage will drop. This verifies that your switch is installed properly.)
  • To Read and Clear Codes
    • Scroll down to “Clear DTCs” to clear codes or “display DTCs” to read out any codes you have.

Troubleshooting basics: Error Code $0281 means there is no power to the Autocal, make sure your key is all the way in the run position (not cranked). If a Duramax, check cigarette lighter fuse. The OBD port runs off of the same fuse and sometimes it will pop. Replace and try again. If code continues to pop up, turn key off for 15 seconds, unplug Autocal, and retry operation. If problem persist, please contact the dealer you purchased the unit from and we will all work to resolve your issue.

Your satisfaction is our #1 concern.
