Code No.B210A +B power supply (low)

 

Code No.B210B +B power supply (high)

CAUTION

• Before replacing the ECU, ensure that the 

power supply circuit, the earth circuit and the 
communication circuit are normal.

• 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 
Immobilizer System 

− How to Register Key ID 

P.54A-33

.)

TROUBLE JUDGMENT

The ETACS-ECU sets the code No. B210A if the 
power supply fuse (IOD fuse) voltage decreases to 
the specified value or less, and sets the code No. 
B210B if the power supply fuse (IOD fuse) voltage 
increases to the specified value or more. However, 
when the status returns to normal, the ETACS-ECU 
automatically erases the code Nos. B210A and 
B210B.

DIAGNOSTIC FUNCTION

If the chassis number which is stored in the 
ETACS-ECU does not correspond to that which is 
stored in the engine-ECU, diagnosis code No.B2206 
will be set.

JUDGMENT CRITERIA

If the chassis number which is stored in the 
ETACS-ECU does not correspond to that which is 
stored in the engine-ECU, the ETACS-ECU will 
determine that the system is defective.

PROBABLE CAUSES

• Chassis number not written

• Malfunction of the ETACS-ECU

• Malfunction of engine-ECU

DIAGNOSIS PROCEDURE

STEP 1. Check the chassis numbers which have 
been stored in the ETACS-ECU and the 
engine-ECU.
Check whether the chassis numbers which have 
been stored in the ETACS-ECU and the engine-ECU 
correspond to the actual chassis number written on 
the vehicle document.

Q: Is the check result normal?

YES : 

Go to Step 2.

NO <engine-ECU> : 

Perform the variant coding for 

the engine-ECU, and then go to Step 2.

NO <ETACS-ECU> : 

Perform the variant coding for 

the ETACS-ECU, and then go to Step 3.

STEP 2. Check whether the diagnosis code is 
reset.
Check again if the diagnosis code is set to the 
ETACS-ECU.
(1) Erase the diagnosis code.
(2) Turn the ignition switch from the LOCK (OFF) 

position to the ON position.

(3) Check if the diagnosis code is set.

Q: Is the diagnosis code set?

YES : 

Replace the engine-ECU, and then go to 

Step 3.

NO : 

The diagnosis is complete.

STEP 3. Check whether the diagnosis code is 
reset.
Check again if the diagnosis code is set to the 
ETACS-ECU.
(1) Erase the diagnosis code.
(2) Turn the ignition switch from the LOCK (OFF) 

position to the ON position.

"255," the diagnosis code No. B2215 is set.

PROBABLE CAUSES

• Malfunction of the ETACS-ECU

Code No.B222C Coding not completed

JUDGMENT CRITERIA

If the ETACS-ECU is in the initial state or the variant 
coding is incomplete, the ETACS-ECU sets the diag-
nosis code No. B222C.

• Malfunction of the ETACS-ECU

Code No.B2353 Ignition power supply (low)

 

Code No.B2354 Ignition power supply (high)

CAUTION

• Before replacing the ECU, ensure that the 

power supply circuit, the earth circuit and the 
communication circuit are normal.

• When the ETACS-ECU of vehicles without 

KOS is replaced, the encrypted code of the 
ignition key needs to be registered to the

decreases to the specified value or less (code No. 
B2353) or increases to the specified value or more 
(code No. B2354). However, when the status returns 
to normal, the code Nos. B2353 and B2354 are auto-
matically erased.
