7.8.4 Forcing Header Identification

The windrower's cab display module (CDM) must recognize the header model in order to proceed with troubleshooting. If
the header wiring has been damaged, or if no header is available, you can force the windrower control module (WCM) to
behave as if a header is attached to the windrower by manually inputting a header identification code.
IMPORTANT:
Forcing a header ID that is different from that of the attached header can damage the windrower and/or the header. Doing
so can cause the header to run too fast, which can cause excessive vibration and component failure.
NOTE:
The WCM will revert to reading NO HEADER each time the engine ignition is cycled.
1. Turn the ignition key to the RUN position or start the
engine.
2. Press PROGRAM (A) and SELECT (B) simultaneously on the
CDM to enter programming mode.
• WINDROWER SETUP? will appear on the upper line.
