- Turn ignition switch to ON position. Simultaneously depress and hold power (PWR) button and recirculation icon button of ATC control panel for 5 seconds, then release. DELAY and recirculation symbol of ATC control panel Vacuum Fluorescent (VF) display window will flash when calibration procedure has begun. Calibration procedure should take less than 20 seconds to complete.
- When DELAY and recirculation icon in ATC control panel VF display stop flashing, calibration procedure has been completed successfully. If VF display remains flashing for longer than 20 seconds, ATC module has detected a fault with a actuator or actuator door operation during calibration test, and DTC/fault message has been stored in ATC module. VF display icons will continuously flash, even after ignition switch has been cycled off and on, until either another calibration test is successfully completed, or until vehicle has been driven about 3 miles. For diagnostic procedures for calibration test failure, see SELF-DIAGNOSTIC SYSTEM in appropriate AUTOMATIC A/C-HEATER SYSTEMS article in AIR CONDITIONING & HEATING.
