P1552 Scion Code - Battery Current Sensor Circuit High Input

Quick Answer

The power generation voltage variable control enables fuel consumption to be decreased by reducing the engine load which is caused by the power generation of the generator. Common causes include Faulty Battery Current Sensor (Built into the Generator Control ECU Assembly), Battery Current Sensor harness is open or shorted, Battery Current Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1552 Scion Description

The power generation voltage variable control enables fuel consumption to be decreased by reducing the engine load which is caused by the power generation of the generator. The battery current sensor built into the Generator Control ECU assembly detects the amount of charge/discharge current. The Generator Control ECU assembly sends voltage generation instructions to the generator assembly based on this signal. The Diagnostic Trouble Code (DTC) will be set when the battery current sensor output value is abnormally high for 30 seconds or more with the ignition switch ON.
