Q: Is the check result normal?

YES : 

Intermittent malfunction. (Refer to GROUP 

00 

−

 How to Cope with Intermittent 

Malfunction 

P.00-6

).)

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-04 door 
lock key cylinder switch (LH) connector terminal 
Nos. 1 and 3 to C-220 ETACS-ECU connector 
terminal Nos. 27 and 28.

NOTE: 

Prior to the wiring harness inspection, check 
intermediate connector C-34, 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.
