Normal Operation
WARNING: This page is about a different variant/trim than selected.
Under normal operation, a 5-volt reference voltage is supplied to the sensors and actuators from the HVAC module through circuit LH111 (BN/WH).
- 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.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- HVAC module
