Conditions for illuminating the fuel fill cap caution

When a malfunction is detected during the first drive cycle with the ECT at engine start-up within the specified temperature range, a Temporary DTC is stored in the PCM memory. If the malfunction recurs during the next (second) drive cycle with the ECT at engine start-up within the specified temperature, the caution is indicated. If the malfunction recurs during the next (third) drive cycle with the ECT at engine start-up within the specified temperature range, the MIL comes on and the DTC and the freeze frame data are stored. The caution is cleared when the MIL comes on.
