Pinpoint Test M : Air Discharge Temperature Sensor Circuit Faults: Notes
Refer to Automatic Climate Control System for schematic and connector information.
Normal Operation and Fault Conditions
The 4 air discharge temperature sensors contain a thermistor. The sensor varies its resistance with the temperature. As the temperature rises, the resistance falls. As the temperature falls, the resistance rises.
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 FCIM senses erratic voltages from the right panel air discharge temperature sensor. |
| B10B3:15 | Right Panel Air Discharge Temperature: Circuit Short To Battery or Open | This DTC sets when the FCIM senses erratic voltages from the right panel air discharge temperature sensor. |
| B10B4:11 | Right Floor Air Discharge Temperature: Circuit Short To Ground | This DTC sets when the FCIM senses erratic voltages from the right floor air discharge temperature sensor. |
| B10B4:15 | Right Floor Air Discharge Temperature: Circuit Short To Battery or Open | This DTC sets when the FCIM senses erratic voltages from the right floor air discharge temperature sensor. |
| B10B5:11 | Left Panel Air Discharge Temperature: Circuit Short To Ground | This DTC sets when the FCIM senses erratic voltages from the left panel air discharge temperature sensor. |
| B10B5:15 | Left Panel Air Discharge Temperature: Circuit Short To Battery or Open | This DTC sets when the FCIM senses erratic voltages from the left panel air discharge temperature sensor. |
| B10B6:11 | Left Floor Air Discharge Temperature: Circuit Short To Ground | This DTC sets when the FCIM senses erratic voltages from the left floor air discharge temperature sensor. |
| B10B6:15 | Left Floor Air Discharge Temperature: Circuit Short To Battery or Open | This DTC sets when the FCIM senses erratic voltages from the left floor air discharge temperature sensor. |
