Step 5. Function diagnosis by using the SWS 
monitor
Check the SWS communication signal, which are 
related to the right turn-signal lamps.

<Selected item> TURN SIGNAL - TURN-SIG. RH

• Turn-signal lamp switch: RH

• Ignition switch: ON

OK:Normal conditions are displayed for all 
the items.

Q: Are the check result normal?

Normal conditions are displayed for all the items. : 

Go to Step 6.

Normal condition is not displayed for item 10 or 11. 
: 

Refer to inspection procedure N-4 "Column 
switch (lighting and turn-signal lamp switch) 
signal is not received 

P.54C-208

."

Normal condition is not displayed for item No.30. : 

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

P.54C-203

."

Step 6. Function diagnosis by using the SWS 
monitor
Check the SWS communication signal, which are 
related to the left turn-signal lamps.

<Selected item> TURN SIGNAL - TURN-SIG. LH

• Turn-signal lamp switch: LH

• Ignition switch: ON

OK: Normal conditions are displayed for all 
the items.

Q: Are the check result normal?

Normal conditions are displayed for all the items. : 

Go to Step 7.

Normal condition is not displayed for item 10 or 11. 
: 

Refer to inspection procedure N-4 "Column 
switch (lighting and turn-signal lamp switch) 
signal is not received 

P.54C-208

."

Normal condition is not displayed for item No.30. : 

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

P.54C-203

."

Step 7. Retest the system.
Check that the turn-signal lamps illuminate.

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

SYMPTOM PROCEDURES

SMART WIRING SYSTEM (SWS) USING SWS MONITOR

54C-173

INSPECTION PROCEDURE L-2: The hazard warning lamps do not illuminate.

CAUTION

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

COMMENTS ON TROUBLE SYMPTOM

If the hazard warning lamps do not illuminate, the 
hazard warning lamp input signal circuit or the 
ETACS-ECU may be defective.

POSSIBLE CAUSES

• Malfunction of the hazard warning lamp switch

• Malfunction of the ETACS-ECU

• Damaged harness wires and connectors

DIAGNOSIS PROCEDURE

Step 1. Check that the turn-signal lamps operate.
Check that the turn-signal lamps illuminate normally.

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Refer to inspection procedure L-1 "The 
turn-signal lamps do not illuminate 

P.54C-170
