When VARTOMS fails, which caution is displayed?

When VARTOMS fails, which caution is displayed?

• A. VAR NR
• B. NR VAR
• C. VARTOMS fault
• D. Warning indicator inverted

Answer: (A)

The caution display uses a two-part tag that identifies the function and its status. When VARTOMS fails, the system shows the function code for that control (VAR) followed by its status (NR). So the message reads VAR NR, meaning the VAR function is Not Ready/Not Responding due to the VARTOMS failure. The other formats don’t fit how the display conveys which function is affected and its condition: a simple VARTOMS fault would be a fault alarm, not the specific caution tag, and an inverted warning indicator isn’t related to the failure indication.
