DTC    B2286    Runnable Signal Malfunction

DTC    P0335    Crankshaft Position Sensor "A" Circuit

for Preparation Click here


DESCRIPTION

The power management control ECU*1 or power source control ECU*2 receives an engine speed signal and information that indicates whether the engine is running or not. It receives the engine speed signal from the ECM via a direct line, and the information about whether the engine is running is received from the ECM via CAN. If the information sent using these 2 methods is inconsistent, this DTC will be stored.

HINT:
When the power management control ECU*1 or power source control ECU*2 is replaced with a new one and the cable is connected to the negative (-) battery terminal, 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.
