Pinpoint Test Q : Air Discharge Temperature Sensor Circuit Faults: Notes

Refer to Manual Climate Control System for schematic and connector information.

Normal Operation and Fault Conditions 

The 2 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 - Vehicles With: Electronic Manual Temperature Control (EMTC) - System Operation and Component Description .

DTC Fault Trigger Conditions 

DTC Description Fault Trigger Conditions
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.
