Simultaneously press the AUTO and OFF buttons. ACC display panel will flash one time, indicating that calibration and self diagnostic test has started. During the calibration “0” will be displayed or any Diagnostic Trouble Codes (DTC’s) that have been detected. Calibration and the self diagnostic test should be completed in about 30 seconds.
Up to 6 DTC’s may be stored at any time. The number stored will be displayed by up to 6 fan speed motor bars. All stored DTC’s are cleared at the start and while the calibration and self diagnostic test are in progress.
