Step 2. Check the door lock key cylinder switch 
(RH).

Refer to GROUP 42 

−

 Door 

P.42-35

.

Q: Is the check result normal?

YES : 

Go to Step 3.

NO : 

Replace the door lock key cylinder switch 
(RH).

Step 3. Measure the resistance at the E-18 door 
lock key cylinder switch (RH) connector.

(1) Disconnect the connector, and measure at the 

wiring harness side.

(2) Resistance between E-18 door lock key cylinder 

switch (RH) connector terminal No. 2 and body 
earth

OK: 2 

Ω

 or less

Q: Is the check result normal?

YES : 

Go to Step 5.

NO : 

Go to Step 4.

Step 4. Check the wiring harness between E-18 
door lock key cylinder switch (RH) connector 
terminal No. 2 and body earth.

NOTE: 

Prior to the wiring harness inspection, check 
intermediate connector C-15, and repair if necessary.

•

Check the earth wires for open circuit.

lock key cylinder switch (RH) connector terminal 
Nos. 1 and 3 to C-220 ETACS-ECU connector 
terminal Nos. 28 and 27.

NOTE: 

Prior to the wiring harness inspection, check 
intermediate connector C-15, and repair if necessary.

•

Check the input line for open circuit.

Q: Is the check result normal?

YES : 

Go to Step 7.

NO : 

Repair the wiring harness.

Step 7. Retest the system.

Check that the passenger's door lock key cylinder 
switch signal is received normally.

Q: Is the check result normal?

YES : 

Intermittent malfunction. (Refer to GROUP 

00 

−

 How to Cope with Intermittent 

Malfunction 

P.00-6

).)

NO : 

Replace the ETACS-ECU.

INSPECTION PROCEDURE N-18: The front passenger’s door lock key cylinder switch signal is not 
detected. <R.H. drive vehicles>

CAUTION

Whenever the ECU is replaced, ensure that the 
input signal circuit is normal.

COMMENTS ON TROUBLE SYMPTOM
Input signal from the front passenger's door lock key 
cylinder switch is used to operate the central door 
locking function. If the signal is abnormal, the central 
door locking function will not work normally.

POSSIBLE CAUSES

•

Malfunction of the front passenger's door lock key 
cylinder switch

•

Malfunction of the ETACS-ECU

•

Damaged harness wires and connectors
