SYMPTOM PROCEDURES

SMART WIRING SYSTEM (SWS) NOT USING SWS MONITOR

54B-209

DIAGNOSTIC PROCEDURE

Step 1. Check the diagnosis code.

When the ignition switch is turned to the LOCK 
(OFF) position, check that the ETACS-ECU does not 
set the diagnosis code.

Q: Is the diagnosis code set?

YES : 

Refer to diagnosis code char

P.54B-17

.

NO : 

Go to Step 2.

Step 2. Pulse check

Check the input signal from the tail lamp switch.

OK: The MUT-II/III sounds or the voltmeter 
needle fluctuates.

Q: Is the check result normal?

All the signals are received normally. : 

Go to Step 

3.

The ignition switch (IG1) signal is not received. : 

Refer to inspection procedure N-2 "The 
ignition switch (IG1) signal is not received 

P.54B-301

."

The tail lamp switch signal is not received. : 

Refer 

to inspection procedure N-5 "The column 
switch (lighting and turn-signal lamp switch) 
signal is not received 

P.54B-319

."

Step 3. Connector check: A-11X front-ECU 
connector

Q: Is the check result normal?

YES : 

Go to Step 4.

NO : 

Repair the defective connector.

Step 4. 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.7 and body earth

OK: System voltage

Q: Is the check result normal?

YES : 

Go to Step 6.

NO : 

Go to Step 5.

Step 5. Check the wiring harness between A-11X 
front-ECU connector terminal No.7 and the 
battery.

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 6. Retest the system.

Check that the tail lamps illuminate normally.

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 : 

Replace the front-ECU.

INSPECTION PROCEDURE J-2: The low-beam headlamps do not illuminate normally.

CAUTION

Whenever the ECU is replaced, ensure that the 
input and output signal circuits are normal.

COMMENTS ON TROUBLE SYMPTOM
If the low-beam headlamps do not illuminate, the 
headlamp switch input circuit or the front-ECU may 
be defective.
