HVAC 87 PINOUT DETAILS PIN NO DESCRIPTION 1 Solar sensor Input to control panel 2 Analog gnd REMOVAL 1. Pry out the front defrost grill. 2. Disconnect the electrical connection of solar load sensor. 3. Rotate the solar load sensor to unlock its snap from adaptor. 4. Take out the sensor. INSPECTION 1. Park the vehicle in a shaded area. 2. Connect the diagnostic tool and monitor the so- lar load input, in the read ECU parameters section of the tool. 3. Drive the vehicle out to another area. The Solar load value should change as per the varying so- lar load conditions. 4. Alternatively switch on the ignition and check the voltage across pin no. J1-6 & J2-1of control panel it should be in the voltage range from 0.5V to 5V. This measurement is to be done when the sensor is connected to control panel. 5. If the voltage is continuously less than 0.3 V then there is a short to ground in the circuit. 6. If the voltage is continuously above 5V, then there is a short to battery in the circuit. 7. If there is no change in the value even after driv- ing from shaded area to bright sunshine and back. Then the sensor is faulty and has to be re- placed. INSTALLATION 1. Fit the solar load sensor into its adaptor. 2. Connect the electrical connection. 3. Fit the front defrost grill. ( Snap Fitted ). E. INCAR TEMPERATURE SENSOR WITH IN- TEGRATED ASPIRATOR FUNCTION: Incar sensor is a sensor that measures the average passenger cabin ambient temperature. It is NTC ( negative temperature coefficient) type temperature sensor means its resistance decreases as the tem- perature increases and vice versa. The sensor shall be capable of sensing a temperature range of – 40°C to 85°C with a resolution of 0.5°C LOCATION: It is fitted on instrument cluster cover.
