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:
ATC system must be in operation for 15 minutes before Codes 23-28 will set. ATC control module will compensate for feedback failures immediately during power up. Codes 23-28 are stored in memory and must be erased. See EXITING DIAGNOSTIC MODE under TESTING.
