Trouble Judgment

WARNING: This page is about a different car, the 2014 Mitsubishi Outlander. However, it is still accessible from the selected car via links, so may be relevant.

The heater controller assembly (A/C-ECU) receives air conditioning control-related signals from the OSS-ECU via the CAN bus lines. If the ECU cannot receive any of the air conditioning control-related signals from the OSS-ECU, diagnostic trouble code U1000 will be stored.
