DIAGNOSTIC PROCEDURE

Step 1. Connector check: B-114 <2000 or 2400- 
L.H. drive vehicles> back-up lamp switch 
connector and C-220 ETACS-ECU connector

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Repair the defective connector.

Step 2. Check the back-up lamp switch

Check the back-up lamp switch (Refer to GROUP 
22B 

−

 Transmission 

P.22B-24

).

Q: Is the check result normal?

YES : 

Go to Step 3.

NO : 

Replace the inhibitor switch.

Step 3. Measure the voltage at the C-220 
ETACS-ECU connector.

(1) Disconnect the connector, and measure at the 

wiring harness side.

(2) Ignition switch: ON
(3) Shift position: R position

(4) Voltage between C-220 ETACS-ECU connector 

terminal No.39 and body earth

OK: System voltage
