Pinpoint Test E : B105A:12, B105A:14, B1A61:11, B1A61:15, B1A69:11, B1A69:15: Notes
WARNING: This page is about a different car, the 2017 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
Refer to Manual Climate Control System for schematic and connector information.
Normal Operation and Fault Conditions
Refer to the In-Vehicle Temperature and Humidity Sensor. 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 |
|---|---|---|
| B105A:12 | Cabin Temperature Sensor Fan: Circuit Short To Battery | This DTC sets in continuous memory and on-demand when the HVAC control module senses greater than expected voltage on the fan circuit, indicating a short to battery. |
| B105A:14 | Cabin Temperature Sensor Fan: Circuit Short To Ground or Open | This DTC sets in continuous memory and on-demand when the HVAC control module senses lower than expected voltage on the fan circuit, indicating a short to ground or an open circuit or an open sensor. |
| B1A61:11 | Cabin Temperature Sensor: Circuit Short to Ground | This DTC sets in continuous memory and on-demand when the HVAC control module senses lower than expected voltage on the sensor feedback circuit, indicating a short to ground. |
| B1A61:15 | Cabin Temperature Sensor: Circuit Short to Battery or Open | This DTC sets in continuous memory and on-demand when the HVAC control module senses greater than expected voltage on the sensor feedback circuit, indicating a short to voltage or an open circuit or an open sensor. |
| B1A69:11 | Humidity Sensor: Circuit Short To Ground | This DTC sets when the HVAC control module senses less than expected voltage on the humidity sensor circuit, indicating a short to ground or sensor. |
| B1A69:15 | Humidity Sensor: Circuit Short To Battery or Open | This DTC sets when the HVAC control module senses greater than expected voltage on the humidity sensor circuit, indicating a short voltage or an open circuit or sensor. |
