Code No. P0513: Immobilizer Malfunction <Vehicles without KOS>
 
 
cautionWhen the ETACS-ECU is replaced, the encrypted code of the ignition key needs to be registered to the ETACS-ECU. (If the encrypted code is not registered, the engine cannot be started. Register the encrypted code as described in GROUP 54A, Immobilizer System - How to Register Key ID .)
 
 
FUNCTION
  • The engine-ECU transmits to and receives from ETACS-ECU a control signal to authenticate the ignition key.
note
  • This code may be displayed due to radio interference if there are multiple registered ignition keys nearby during engine start.
  • This code may be displayed when the transponder ID code is registered.
  • This code is also displayed when the ignition key code is not recognised.
  • When this code is displayed, it is also sent to immobilizer system.
 
 
TROUBLE JUDGEMENT
Check Conditions
  • Ignition switch is "ON" position
  • Communication with ETACS-ECU is normal.
Judgement Criterion
  • When it was different in the encrypted code sent from ETACS-ECU and operation result by engine-ECU.
 
 
FAIL-SAFE AND BACKUP FUNCTION
  • Engine start is prohibited.
 
 
PROBABLE CAUSES
  • Failed ETACS-ECU
  • Failed engine-ECU
 
 
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-IIISE other system diagnosis code
  • Reconfirmation whether diagnosis code is set in ETACS-ECU.
Is the diagnosis code set?
Perform the troubleshooting of ETACS-ECU system (Refer to GROUP 54A - Immobilizer System - Diagnosis Code Chart ).
Go to Step 2.
 
STEP 2. M.U.T.-IIISE diagnosis code
  • Reconfirmation of diagnosis code.
Is the diagnosis code set?
Replace the ETACS-ECU. After the replacement, put the each identification code into ETACS-ECU. (Refer to GROUP 54A - Immobilizer System - How to Register key ID ). Then go to Step 3.
Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent malfunctions).
 
STEP 3. M.U.T.-IIISE diagnosis code
  • Reconfirmation of diagnosis code.
Is the diagnosis code set?
Replace the engine-ECU.
Check end.
