Test C: DTC B2426, B2427, B2795 Or B2796 - Solar Radiation Sensor Circuit Open Or Short To Ground

PINPOINT TEST C: DTC B2426, B2427, B2795 OR B2796 - SOLAR RADIATION SENSOR CIRCUIT OPEN OR SHORT TO GROUND

Normal Operation
Under normal operation, the solar radiation sensor receives a ground through circuit GD116 (BK/VT). A 5-volt reference voltage is supplied to the solar radiation sensor from the HVAC module - electronic automatic temperature control (EATC) or HVAC module - dual automatic temperature control (DATC) through circuits (LH) VH416 (VT/GY) and (RH) VH417 (YE/OG).
