   Procedure/Specifications 

   1. Turn the vehicle to the ON mode.

   2. Measure the voltage between terminals with the (+) probe on terminal No. 3 and the (-) probe on terminal No. 2 with the connector connected. (Figure 1)3. Compare the voltage readings with the specifications shown in the graph; the voltage should be within the specifications. (Figure 2)

   Result 

   • If the result is not as specified, replace the humidity/in-car temperature sensor.

   Procedure/Specifications 

   1. Test the in-car temperature sensor while holding it in front of the center dashboard vent. (Figure 1)

   • Measure the resistance with the system set to MAX COOL (Lo).
   • Measure the resistance with the system set to MAX HOT (Hi).

   2. Compare the resistance readings with the specifications shown in the graph, the resistance should be within the specifications. (Figure 2)

   Result 

   • If the result is not as specified, replace the humidity/in-car temperature sensor.
