Indicator Logic: ’03 Accord

On ’03 Accord EXs with leather and ’03 Accord EX V6s, the outside temperature
indicator keeps bogus readings to a minimum by delaying the
refreshing of the display until you’re driving the vehicle faster than 19 mph,
and by limiting the display change rate. Here’s how the logic works:
When you turn the ignition switch to ON (II):
• If the engine coolant temperature is less than 60°C (140°F), the display shows
the current outside air temperature.
• If the engine coolant temperature is greater than 60°C (140°F), the display
shows the temperature that was stored in memory when
you turned the switch to LOCK (0). The display doesn’t refresh from this
reading until you drive the vehicle faster than 19 mph for at
least 90 seconds. Once this criteria is met:
• If the measured outside air temperature is greater than the displayed
temperature, the displayed temperature rises 1°C per minute
(about 1.8°F) until the two temperatures match.
• If the measured outside air temperature is less than the displayed
temperature, the displayed temperature drops to match the measured
outside air temperature after about 20 seconds.

If you need to calibrate the outside temperature indicator, refer to page
22-240 of the 2003 Accord S/M.
