DIAGNOSTIC TROUBLE CODE PROCEDURES

Diagnosis code 11: Trouble related to the ETACS-ECU

DIAGNOSIS CODE SET CONDITIONS
The ETACS-ECU monitors the data, which the ECU 
itself sends. If errors occur consecutively 15 times 
(for 0.6 seconds), a diagnosis code will be set. Then, 
if the data does not contain any errors consecutively 
15 times (for 0.6 seconds), the ECU will stop sending 
the diagnosis code.

POSSIBLE CAUSES

•

Malfunction of the ETACS-ECU

DIAGNOSTIC PROCEDURE

Check whether the diagnosis code is reset.
(1) Erase the diagnosis code.
(2) Again check that diagnosis code No.11 is set.

Q: Is diagnosis code No.11 set?

YES : 

Replace the ETACS-ECU.

NO : 

The trouble can be an intermittent 
malfunction (Refer to GROUP 00 

−

 How to 

Cope with Intermittent Malfunction 

P.00-6

).

Code No.

54B-19

DIAGNOSIS CODE SET CONDITIONS
If the column switch ignores the data request signal 
sent by the ETACS-ECU (three times or more for one 
second), this diagnosis code will be set. Then, when 
the column switch observes the request signal for 
one second, the ECU will stop sending the diagnosis 
code.

POSSIBLE CAUSES

•

Malfunction of the column switch

•

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.12 

is not reset.

Q: Is diagnosis code No.12 set?

YES : 

Go to Step 5.

NO : 

Go to Step 2.

Step 2. Connector check: C-310 column switch 
connector

Q: Is the check result normal?

YES : 

Go to Step 3.

NO : 

Repair the defective connector.

Step 3. Measure the voltage at C-310 column 
switch connector.

(1) Remove the column switch, and measure at the 

wiring harness side.

(2) Voltage between C-310 column switch connector 

terminal No.1 and body earth

OK: System voltage

Q: Is the check result normal?

YES : 

Replace the column switch.

NO : 

Go to Step 4.
