Code No. 22 (Control Module Error)

If Code No. 22 occurs, control module has identified out-of-range data. Replace ATC control panel. See ATC CONTROL MODULE/CONTROL PANEL  under REMOVAL & INSTALLATION.

NOTE: Failure Codes 23-28 are set during normal ATC operation. ATC system must be in operation for 15 minutes before these codes will set. ATC control module will compensate for feedback failures immediately during power up. Codes will not be set before 15 minutes. Codes are then stored in memory and must be erased. See EXITING DIAGNOSTIC MODE  under TESTING.
