Test B: DTC B2796 Or DTC B2795 - Solar Radiation Sensor Open Circuit Or Short To Ground
PINPOINT TEST B: DTC B2796 OR DTC B2795 - SOLAR RADIATION SENSOR OPEN CIRCUIT OR SHORT TO GROUNDNormal Operation
Under normal operation, the sunload sensor receives a ground through circuit 875 (BK/LB). A 5-volt reference voltage is supplied to the sunload sensor from the HVAC module - electronic automatic temperature control (EATC) through circuit 468 (BN).
- DTC B2795 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 B2796 Solar Radiation Sensor Circuit Open - The module senses no voltage drop on the sensor reference voltage circuit, indicating an open circuit.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Sunload sensor
- HVAC module - EATC
