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
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.
