DIAGNOSTIC PROCEDURE - MODE DOOR FEEDBACK FAILURE - ATC & MTC

TEST ACTION APPLICABILITY
1
NOTE: If the vehicle is equipped with Manual Temperature Control (MTC), proceed directly to the conclusion question for this test and answer No to the question.
Park the vehicle either indoors or in a shaded area.Turn the ignition on.With the DRBIII®, read Body Computer DTCs.Does the DRBIII® display Sun Load Sensor Failure or In Car Temperature Sensor Failure?Yes --> Perform appropriate test(s).Calibration must be performed after repair/replacement is completed.Perform BODY VERIFICATION TEST - VER 1 .No, Vehicles With ATCGo To 2No, Vehicles With MTCGo To 5		 All
2 Turn the ignition on.
NOTE: Voltages specified are from shining a 25 watt incandescent bulb on the Sensor through the windshield of a vehicle parked indoors. Performing this test with a higher watt bulb / with a vehicle parked in the sun will result in lower voltage readings.

With the DRBIII® in Sensor Display, monitor Sun Sensor voltage while shining an incandescent lamp (min 25 watt) directly on the Sun Sensor. The voltage reading should change from approx 5.0 volts (without the light) to 4.3 volts (with the light).
Does the voltage reading change accordingly?
