Malfunction of ETACS-ECU power supply circuit

P.54A-311

SYMPTOM PROCEDURES

Malfunction of ETACS-ECU power supply circuit

CAUTION

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 registered, the engine can-
not be started. Register the encrypted code as 
described in Immobilizer System 

− How to Regis-

ter Key ID 

P.54A-33

.)

COMMENTS ON TROUBLE SYMPTOM

If the ETACS-ECU functions do not work at all, the 
ETACS-ECU power supply system, earth system, or 
ETACS-ECU may have a problem.

PROBABLE CAUSES

• Damaged harness wires and connectors

• Malfunction of the ETACS-ECU

DIAGNOSIS PROCEDURE

STEP 1. Resistance measurement at ETACS-ECU 
connector (EARTH, SGND terminal).
(1) Disconnect the connector, and measure at the 

wiring harness side.

(2) Measure the resistance between the 

ETACS-ECU connector (EARTH terminal) and 
body earth.

OK: Continuity exists (2 

Ω or less)

(3) Measure the resistance between the 

ETACS-ECU connector (SGND terminal) and 
body earth.

OK: Continuity exists (2 

Ω or less)

Q: Is the check result normal?

YES : 

Go to Step 3.

NO : 

Go to Step 2.

STEP 2. Check of open circuit in EARTH, SGND 
line between ETACS-ECU connector and body 
earth.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

− How to 

use Troubleshooting/inspection Service 
Points 

− How to Cope with Intermittent 

Malfunction ).

NO : 

Repair the connector(s) or wiring harness.

STEP 3. Voltage measurement at ETACS-ECU 
connector (+B terminal).
(1) Disconnect the connector, and measure at the 

wiring harness side.

(2) Check the voltage between the ETACS-ECU 

connector (+B terminal) and body earth.

OK: System voltage

Q: Is the check result normal?

YES : 

Go to Step 5.

NO : 

Go to Step 4.

STEP 4. Check of short to power supply, short to 
earth, and open circuit in IOD1 line between 
fusible link and ETACS-ECU connector.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

− How to 

use Troubleshooting/inspection Service 
Points 

− How to Cope with Intermittent 

Malfunction ).

NO : 

Repair the connector(s) or wiring harness.

STEP 5. Voltage measurement at ETACS-ECU 
connector (+B1 terminal).
(1) Disconnect the connector, and measure at the 

wiring harness side.

(2) Check the voltage between the ETACS-ECU 

connector (+B1 terminal) and body earth.

OK: System voltage

Q: Is the check result normal?

YES : 

Go to Step 7.

NO : 

Go to Step 6.

54A-312

STEP 6. Check of short to power supply, short to 
earth, and open circuit in +B1 line between 
fusible link and ETACS-ECU connector.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

− How to 

use Troubleshooting/inspection Service 
Points 

− How to Cope with Intermittent 

Malfunction ).

NO : 

Repair the connector(s) or wiring harness.

STEP 7. Retest the system
Check that the ETACS-ECU functions work normally.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

− How to 

use Troubleshooting/inspection Service 
Points 

− How to Cope with Intermittent 

Malfunction ).

NO : 

Replace the ETACS-ECU.

INPUT SIGNAL PROCEDURES

Inspection Procedure 1: The ignition switch (ACC) signal is not received.

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

COMMENTS ON TROUBLE SYMPTOM

If there is an error to the input signal (ACC) from the 
ignition switch <Vehicles without KOS> or OSS-ECU 
<Vehicles with one touch start system>, or if the ACC 
relay in ETACS-ECU does not function normally, the 
ignition switch (ACC) signal is no longer output to the 
communication line.
