NOTE:
If power from the battery is interrupted, the climate control unit will go into a non-configured state because the memory for the configuration information is erased. If the ignition is switched ON (engine off) at this time, DTC U2300:55 is detected.
Normally, the configuration is re-performed within 6 s after the ignition is switched ON (engine off).
After performing the configuration, DTC U2300:55 will be cleared if the ignition is switched ON (engine off) after the ignition is switched off.

3. Switch the ignition off.
4. Connect the M-MDS to the DLC-2.
5. Expose the solar radiation sensor to natural sunlight.NOTE:
If natural sunlight is not shone on the solar radiation sensor, the climate control unit determines a malfunction and indicates DTC “B1A63:12, B1A63:13, B1A64:12, B1A64:13”.
6. After the vehicle is identified, select the following items from the initialization screen of the M-MDS.a. Select “Self Test”.b. Select “All CMDTCs”.
