DTC B2281 "P" Signal Malfunction: Description
WARNING: This page is about a different car, the 2008 Lexus IS 350. However, it is still accessible from the selected car via links, so may be relevant.
The power source control ECU and the shift lock control ECU are connected by a cable and the BEAN. If the cable information and BEAN information are inconsistent, this DTC will be output.
HINT:
When the power source control ECU is replaced with a new one and the negative (-) battery terminal is connected, the power source mode becomes the IG-ON mode. When the battery is removed and reinstalled, the power source mode that was selected when the battery was removed is restored.
