Step 2. Pulse check

Check the input signals below, which are related to 
the ignition key cylinder illumination lamp.

NOTE: 

*

: Vehicles with keyless entry system

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 key reminder switch signal is not received. : 

Refer to inspection procedure N-9 "The key 
reminder switch signal is not received 

P.54B-334

."

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

Refer to inspection procedure N-4 "The front 
door switch signal is not received <L.H. 
drive vehicles>

P.54B-315

 or <R.H. drive 

vehicles>

P.54B-317

."

Step 3. Connector check: C-304 key reminder 
switch connector

Q: Is the check result normal?

YES : 

Go to Step 4.

NO : 

Repair the defective connector.

Step 4. Check the bulb of the ignition key 
cylinder illumination lamp.

Check the bulb of the ignition key cylinder 
illumination lamp.

Q: Is the check result normal?

YES : 

Go to Step 5.

NO : 

Replace the bulb of the ignition key cylinder

HEADLAMP AND TAIL LAMP

INSPECTION PROCEDURE J-1: The tail lamps do not illuminate normally.

CAUTION

Whenever the ECU is replaced, ensure that the
