Diagnosis Item 9: Diagnose when the M.U.T.-III cannot receive the data sent by ETACS-ECU.

CAUTION

• When servicing a CAN bus line, earth yourself 

by touching a metal object such as an 
unpainted water pipe. If you fail to do, a com-
ponent connected to the CAN bus line may be 
broken.

• 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 diagnostic result demonstrates that "the 
M.U.T.-III cannot receive the sent data from the 
ETACS-ECU" when the M.U.T.-III checks the periodi-
cally sent data from each ECU and cannot receive 
the ETACS-ECU data only.

TROUBLE JUDGEMENT CONDITIONS

M.U.T.-III judges the trouble when the periodically 
sent data from ETACS-ECU cannot be received. 

PROBABLE CAUSES

• Damaged harness wires and connectors

• Power supply circuit malfunction of the 

ETACS-ECU

• Malfunction of the ETACS-ECU
