Pinpoint Test M : Air Discharge Temperature Sensor Circuit Faults: Notes
WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.
Refer to Wiring Diagrams 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. REFER to: Climate Control System - System Operation and Component Description .
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 panel 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 panel 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. |
