Using an OBD2 scanner can help diagnose issues with your car’s air conditioning system. While generic OBD2 codes don’t directly address AC problems, using a customized profile or backup for specific car models, like the Clarity PHEV, within an app like Car Scanner, can provide access to manufacturer-specific Obd2 Ac Codes and data related to A/C pressure.
Accessing AC Pressure Data with Car Scanner
A custom profile for the Clarity PHEV, available in the Car Scanner app, provides access to crucial data like battery capacity. However, this profile may not include all available parameters, specifically those added later by community members, like A/C pressure.
To access these additional parameters, a backup set is available. This backup, downloadable as a .zip file, contains all the latest known parameters and example dashboards, including one specifically displaying A/C pressure alongside inside and outside temperatures.
Using the Backup Set for Enhanced Diagnostics
To utilize this comprehensive dataset:
- Download and Extract: Download the .zip file containing the backup set and extract its contents.
- Import into Car Scanner: Within the Car Scanner app settings, locate the import function and select the extracted backup file. This process imports all custom parameters and dashboards.
- Navigate to the AC Pressure Dashboard: Open the fifth dashboard included in the backup set. This dashboard should display the A/C pressure along with relevant temperature readings.
Interpreting AC Pressure Readings
Compare the displayed A/C pressure with a reference table corresponding to the current ambient temperature. While a perfect match isn’t always expected due to sensor tolerances, the reading should be relatively close. Significant deviations could indicate a problem with the AC system.
Updates to parameters, including potential new OBD2 AC codes, will be included in future backup set releases in the original forum thread. Using the latest backup ensures access to the most comprehensive diagnostic information.
