DTC B2286 Runnable Signal Malfunction: Description
WARNING: This page is about a different car, the 2007 Lexus ES 350. However, it is still accessible from the selected car via links, so may be relevant.
This DTC is output when serial communication signals and CAN communication signals in the circuit between the main body ECU and ECM are inconsistent.
HINT:
When the main body 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.
After the main body ECU is replaced, perform the registration procedures for the engine immobilizer system (See REGISTRATION ).
