DTC DISPLAY [CLIMATE CONTROL UNIT (MANUAL AIR CONDITIONER)]

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.
