Code No. P0513: Immobilizer Malfunction

CAUTION

• When the ETACS-ECU of vehicles without 

KOS is replaced, the encrypted code of the 
ignition key needs to be registered to the 
ETACS-ECU. (If the encrypted code is not reg-
istered, the engine cannot be started. Regis-
ter the encrypted code as described in 
GROUP 54A, Immobilizer System 

− How to 

Register Key ID .)

FUNCTION

• The engine-ECU transmits to and receives from 

KOS-ECU <Vehicles with KOS> or ETACS-ECU 
<Vehicles without KOS> a control signal to 

authenticate the ignition key.

NOTE: 

.

•

This code may be displayed due to radio interfer-
ence if there are multiple registered ignition keys 
nearby during engine start.

•

This code may be displayed when the trans-
ponder ID code is registered.

•

This code is also displayed when the ignition key 
code is not recognized.

•

When this code is displayed, it is also sent to 
KOS-ECU <Vehicles with KOS> or ETACS-ECU 
<Vehicles without KOS>
