B2795
--
PINPOINT TEST 3: DTC B2426, B2427, B2795 OR B2796 - SOLAR RADIATION SENSOR CIRCUIT OPEN OR SHORT TO GROUND - HYBRID
Normal Operation
The autolamp/sunload sensor receives a ground through circuit (B/L). A 5-volt reference voltage is supplied to the autolamp/sunload sensor from the dual automatic temperature control (DATC) module through circuit (Y/O) (LH) and circuit (V/GY) (RH).
- DTC B2426 (Passenger Solar Radiation Sensor Circuit Open) - The module senses no voltage drop on the sensor reference voltage circuit, indicating an open circuit.
- DTC B2427 (Passenger Solar Radiation Sensor Circuit Short to Ground) - The module senses excessive voltage drop on the sensor reference voltage circuit, indicating a short directly to ground.
- DTC B2795 (Driver Solar Radiation Sensor Circuit Short to Ground) - The module senses no voltage drop on the sensor reference voltage circuit, indicating an open circuit.
- DTC B2796 (Driver Solar Radiation Sensor Circuit Open) - The module senses excessive voltage drop on the sensor reference voltage circuit, indicating a short directly to ground.
Possible Causes
- Wiring, terminals or connectors
- Autolamp/Sunload sensor
- DATC module
