COMMENTS ON TROUBLE SYMPTOM
If this circuit is defective and the ignition switch is at 
the LOCK (OFF) position, the ETACS-ECU does not 
work. In this case, the functions below will be 
suspended.

•

Lamp reminder function

•

Keyless entry system

•

Ignition key cylinder illumination lamp

•

Headlamp automatic-shutdown function

However, when the ignition switch is at the ON 
position, the functions below will work.

•

Reading diagnosis code and checking input 
signal by MUT-II/III.

•

Central door locking

•

Headlamp and tail lamp

•

Hazard warning lamp

•

Room lamps

POSSIBLE CAUSES

•

Malfunction of the ETACS-ECU

•

Damaged harness wires and connectors

DIAGNOSTIC PROCEDURE

Step 1. Connector check: C-217 ETACS-ECU 
connector

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Repair the defective connector.

Step 2. Measure the voltage at the C-217 
ETACS-ECU connector.

(1) Remove the ETACS-ECU, and measure at the 

junction block side.

(2) Voltage between C-217 ETACS-ECU connector 

terminal No.20 and body earth.

OK: System voltage

Q: Is the check result normal?

YES : 

Go to Step 4.

NO : 

Go to Step 3.

SYMPTOM PROCEDURES

SMART WIRING SYSTEM (SWS) NOT USING SWS MONITOR

54B-56

Prior to the wiring harness inspection, check 
intermediate connector C-116, joint connector C-02 
and junction block connector C-202, 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 4. Measure the resistance at the C-217 
ETACS-ECU connector.

(1) Remove the ETACS-ECU, and measure at the 

junction block side.

(2) Continuity between C-217 ETACS-ECU 

connector terminal No.3 and body earth.

OK: 2

Ω

 or less

Q: Is the check result normal?

YES : 

Go to Step 6.

NO : 

Go to Step 5.
