Output Circuit Actuator Tests
In the Output Circuit/Actuator Test mode, the output circuits can be viewed, monitored, overridden, and tested. If a failure occurs in an output circuit, test the circuit by overriding the system. Test the actuator through its full range of operation. When the override control has been activated, the Test Selector display will be flashing. The Test Selector will display feedback information about the output circuit being tested.
1. To begin the Output Circuit/Actuator Tests you must be in the Select Test mode.
2. With a "00" value displayed in the Test Selector and no stick man, turn the rotary temperature control knob until the test number you are looking for appears in the Test Selector display See the Circuit Testing charts for a listing of the test numbers, test items, test types, system tested, and displayed values.
3. To see the output value, depress the A/C or Recirc button. The values displayed will represent the output from the ATC control module.
4. To enter the actuator test, depress the A/C or Recirc button. The Test Selector display will blink, indicating you are in the actuator test mode. Manual tests are those in which you will have to depress and hold the A/C or Recirc button to control the output. Automatic tests are those in which you will have to depress the A/C or Recirc button once to generate the output.
