STEP 3. Connector check: Immobilizer-ECU 
connector C-304-1 and engine control relay 
connector B-17X

Q: Are immobilizer-ECU connector C-304-1 and 

engine control relay connector B-17X in good 
condition?

YES : 

Go to Step 4.

NO : 

Repair or replace the component(s). 
Confirm that MUT-II/III communicates 
normally.

STEP 4. Check the harness wires between 
immobilizer-ECU connector C-304-1 (terminal 1) 
and engine control relay connector B-17X 
(terminal 1).

STEP 5. Resistance measurement at 
immobilizer-ECU connector C-304-1.

(1) Disconnect immobilizer-ECU connector C-304-1. 

(2) Measure the resistance between terminal 4 and 

earth.

OK: 2 ohms or less

Q: Is the check result normal?

YES : 

Go to Step 8.

NO : 

Go to Step 6.

connector C-304-1

Q: Is immobilizer-ECU connector C-304-1 in good 

condition?

YES : 

Go to Step 7.

NO : 

Repair or replace the component(s). 
Confirm that MUT-II/III communicates 
normally.
