DIAGNOSTIC PROCEDURE

Step 1. Connector check: E-18 door lock key
cylinder switch (RH) connector

Q: Is the check result normal?

YES :

Go to Step 2.

NO :

Repair the defective connector.

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.

NO :

Repair the wiring harness.

Step 5. Connector check: C-220 ETACS-ECU
connector

Q: Is the check result normal?

YES :

Go to Step 6.

NO :

Repair the defective connector.

Step 6. Check the wiring harness from E-18 door
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
