Hi Bob,

Thank you for the donation.

This is for auto HVAC which is equipped with self diagnostic.

SELF-DIAGNOSTIC SYSTEM
Entering Self-Diagnostics
1. Set A/C-heater control panel to display degrees Fahrenheit. Start engine (vehicle not moving) and set temperature control to 75 °F. To enter self-diagnostic mode, simultaneously press and hold floor, mix, and defrost buttons.
See Fig. above .
When ATC panel display begins to blink, release all 3 buttons.
2. The display will continue to blink until it completes its tests and calibrations. Any ATC-related diagnostic trouble codes stored in BCM will be displayed when blinking stops. If there are no trouble codes, system will return to normal operation.
3. Trouble codes will appear on display in numerical form. Only one number will be displayed at a time. Press panel (vent) button to scroll through any additional trouble codes.
See DIAGNOSTIC TROUBLE CODES table for list of codes. Exiting Self-Diagnostics & Clearing Codes To exit self-diagnostics, turn ignition off. To clear codes, disconnect negative battery cable for at least 10 minutes.
DIAGNOSTIC TROUBLE CODES
NOTE: If in-vehicle temperature sensor is disconnected while it is operating, Code 26 will set and automatic A/C-heater control panel display will go blank. To correct condition, clear Code 26 from BCM. See EXITING SELF- DIAGNOSTICS AND CLEARING CODES.
