Note
If the auxiliary battery voltage is low, the climate control seat system may not operate. When "High Power Consumption Partial Limit On AC/Heater Operation" is displayed on the multi-information display in the combination meter assembly, inspect the auxiliary battery, referring to On-vehicle Inspection for the charging system.
The following malfunctions may occur if a radio receiver assembly from another vehicle is installed to this vehicle. Therefore, when replacing the radio receiver assembly be sure to replace it with new one.
Communication malfunction DTC is output

Tech Tips
If the auxiliary battery voltage is low, the climate control seat system may not operate. When "High Power Consumption Partial Limit On AC/Heater Operation" is not displayed on the multi-information display in the combination meter assembly, check the Data List item "Battery Control Count (Body ECU)".
Use the table below to help determine the cause of problem symptoms. If multiple suspected areas are listed, the potential causes of the symptoms are listed in order of probability in the "Suspected Area" column of the table. Check each symptom by checking the suspected areas in the order they are listed. Replace parts as necessary.
Inspect the fuses and relays related to this system before inspecting the suspected areas below.
