B1A69:11

-
PINPOINT TEST 25: DTC B1A69:11 OR 15 - HYBRID

See the Tribute Wiring Diagram for schematic information.

Normal Operation

Under normal operation, the in-vehicle temperature/humidity sensor is grounded through circuit (GY/L). A 5-volt reference voltage is supplied to the in-vehicle temperature/humidity sensor from the HVAC module through circuit (BR/W). The HVAC module receives the humidity value through circuit (W/L).

- DTC B1A61:11 (Humidity Sensor: Circuit Short to Ground) - The module senses excessive voltage drop on the sensor reference voltage circuit, indicating a short directly to ground.
- DTC B1A61:15 (Humidity Sensor: Circuit Short to Battery or Open) - The module senses no voltage drop on the sensor reference voltage circuit, indicating a short directly to voltage or an open circuit.

Possible Causes
- Wiring, terminals or connectors
- In-vehicle temperature/humidity sensor
- HVAC module
