Normal Operation and Fault Conditions
The air discharge sensors supply a varying voltage to the HVAC control module based on the temperature of the air being discharged from the vent. The HVAC control module adjusts the system based on the voltage from each sensor.
Each air discharge sensor is supplied voltage from the HVAC control module but all sensors share a common sensor ground. An open, a short to ground, a short to voltage on one or more of these circuits or a failed air discharge sensor causes the HVAC control module to set one or more Diagnostic Trouble Codes (DTCs).
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B10B3:11 | Right Panel Air Discharge Temperature: Circuit Short To Ground | This DTC sets when the HVAC control module senses erratic voltages from the appropriate air discharge temperature sensor. |
| B10B3:15 | Right Panel Air Discharge Temperature: Circuit Short To Battery or Open | |
| B10B4:11 | Right Floor Air Discharge Temperature: Circuit Short To Ground | |
| B10B4:15 | Right Floor Air Discharge Temperature: Circuit Short To Battery or Open | |
| B10B5:11 | Left Panel Air Discharge Temperature: Circuit Short To Ground | |
| B10B5:15 | Left Panel Air Discharge Temperature: Circuit Short To Battery or Open | |
| B10B6:11 | Left Floor Air Discharge Temperature: Circuit Short To Ground | |
| B10B6:15 | Left Floor Air Discharge Temperature: Circuit Short To Battery or Open |
