NOTE: 

Prior to the wiring harness inspection, check junction 
block connector C-210, and repair if necessary.

Q: Is the check result normal?

YES : 

Go to Step 8.

NO : 

Repair the wiring harness.

Step 8. Retest the system.

Check that the front or rear room lamp illuminates 
and extinguishes normally.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00

SYMPTOM PROCEDURES

SMART WIRING SYSTEM (SWS) NOT USING SWS MONITOR

54B-287

INSPECTION PROCEDURE M-2: The front and rear room lamp do not illuminate or extinguish 
normally. <Vehicles with keyless entry system>

CAUTION

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

COMMENTS ON TROUBLE SYMPTOM
The ETACS-ECU operates this function in 
accordance with the input signals below.

•

Ignition switch (IG1)

•

Key reminder switch

•

All of the door switches

•

Driver's door lock actuator

•

Interior lamp loaded signal

If this function does not work normally, these input 
signal circuit(s), the interior lamp 
automatic-shutdown function or the ETACS-ECU 
may be defective. The delay-off setting of this 
function can be changed by the adjustment function 
(default setting; 15 seconds).

POSSIBLE CAUSES

•

Malfunction of the key reminder switch

•

Malfunction of the door switches

•

Malfunction of the driver's door lock actuator

•

Malfunction of the ETACS-ECU

•

Damaged harness wires and connectors

DIAGNOSTIC PROCEDURE

Step 1. Check the adjustment function.

Check that the room lamp delay-off time has been 
set to other than "0 second" by the adjustment 
function.

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Use the adjustment function to set the room 
lamp delay-off time to other than "0 second." 
Refer to 

P.54B-393

.

Step 2. Check the power supply circuit.

When the ignition switch is turned to the LOCK 
(OFF) position, check if the hazard warning lamps 
illuminate.

Q: Is the check result normal?

YES : 

Go to Step 3.

NO : 

Refer to inspection procedure A-2 "Check 
the ETACS-ECU battery power supply 
circuit" 

P.54B-52

.

Step 3. Pulse check

Check the input signals below, which are related to 
the front and rear room lamps.

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 

4.

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

."

All the door switch signals are not received. : 

Refer to inspection procedure N-11 "All the 
door switch signals are not received <L.H. 
drive vehicles>

P.54B-342

  or <R.H. drive 

vehicles>

P.54B-346

 ."

The driver's door lock actuator switch signal is not 
received. : 

Refer to inspection procedure N-12 

"The driver's door lock actuator switch 
signal is not received <L.H. drive 
vehicles>

P.54B-350

  or <R.H. drive
