Step 6. 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: Is 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 Q-6 "The 
column switch (lighting and turn-signal lamp 
switch) signal is not received 

P.54C-478

."

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

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

P.54C-460

."

Step 7. SWS monitor data list.

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: Is the check result normal?

Normal conditions are displayed for all the items. : 

Go to Step 8.

Normal condition is not displayed for item 10 or 11. 

Refer to inspection procedure Q-6 "The 
column switch (lighting and turn-signal lamp 
switch) signal is not received 

P.54C-478

."

Step 8. 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 

Cope with Intermittent Malfunction 

P.00-5

).

NO : 

Replace the ETACS-ECU.
