DIAGNOSTIC PROCEDURE

Step 1. 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 2.

NO : 

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

P.54B-52

."

Step 2. 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 

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

."

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

vehicles>

P.54B-354

."

Step 3. Connector check: D-05 front room lamp 
connector, D-11 rear room lamp connector

Q: Is the check result normal?
