PINPOINT TEST 21: DTCs C1B14:11 AND 12 - HYBRID

See the Tribute Wiring Diagram for schematic information.

Normal Operation

Under normal operation, a 5-volt reference voltage is supplied to the sensors and actuators from the HVAC module through circuit (BR/W).

- DTC C1B14:11 (Sensor Supply Voltage A: Circuit Short to Ground) - The module senses less than 0.1 volt on the sensor reference voltage circuit, indicating a short directly to ground.
- DTC C1B14:12 (Sensor Supply Voltage A: Circuit Short to Battery) - The module senses greater than 4.9 volts on the sensor reference voltage circuit, indicating a short directly to voltage.

Possible Causes
- Wiring, terminals or connectors
- HVAC module
