DIAGNOSIS CODE SET CONDITIONS
If the front-ECU has sent abnormal signal to the 
ETACS-ECU for consecutively 15 communication 
cycles (0.6 second), the diagnosis code will be set. If 
the front-ECU has sent normal signal to the 
ETACS-ECU for consecutively 15 communication 
cycles (0.6 second), the ETACS-ECU will stop 

sending the diagnosis code.

POSSIBLE CAUSES

•

Malfunction of the front-ECU

•

Malfunction of the ETACS-ECU

•

Damaged harness wires and connectors

DIAGNOSTIC PROCEDURE

Step 1. Use the MUT-II/III to confirm a diagnosis 
code. (MUT-II/III diagnosis code)
(1) Ignition switch: ON
(2) On completion, check that diagnosis code No.13 

is not reset.

Q: Is diagnosis code No.13 set?

YES : 

Go to Step 5.

NO : 

Go to Step 2.

Step 2. Connector check: A-11X front-ECU 
connector

Q: Is the check result normal?

YES : 

Go to Step 3.

NO : 

Repair the defective connector.

Step 3. Measure the voltage at A-11X front-ECU 
connector.

(1) Remove the front-ECU, and measure at the relay 

box side.

(2) Voltage between A-11X front-ECU connector 

terminal No.5 and body earth

OK: System voltage

Q: Is the check result normal?

YES : 

Replace the front-ECU.

NO : 

Go to Step 4.

Step 4. Check the wiring harness between A-11X 
front-ECU connector terminal No.5 and the 
battery.

NOTE: 

<R.H. drive vehicles> Prior to the wiring harness 
inspection, check intermediate connectors A-14, 
C-116, C-122, junction block connectors C-202 and 
C-204, and repair if necessary.

•

Check the power supply line for open circuit.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

−

 How to 

Cope with Intermittent Malfunction 

P.00-6

).

NO : 

Repair the wiring harness.

Step 5. Connector check: A-12X front-ECU 
connector

Q: Is the check result normal?

YES : 

Go to Step 6.

NO : 

Repair the defective connector.
