NOTE: 

Prior to the wiring harness inspection, check key 
reminder switch connector C-304, intermediate 
connector C-104, and repair if necessary.

Q: Are the harness wires between immobilizer-ECU 

connector C-304-1 (terminal 3) and engine-ECU 
<2000> connector C-136 (terminal 51) or 
engine-ECU <2400-M/T>, engine-A/T-ECU 
<2400-A/T> connector C-141 (terminal 65) in good 
condition?

YES : 

Go to Step 10.

NO : 

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

STEP 10. Replace the immobilizer-ECU.

Replace the immobilizer-ECU.

Q: Did the communication with MUT-II/III become 

possible after replacing the immobilizer-ECU?

YES : 

Register the password (secret code) and 

encrypted code 

P.54A-24

. Confirm that 

MUT-II/III communicates normally.

NO : 

Go to Step 11.

STEP 11. Recheck for malfunction.

Q: Is a malfunction eliminated? 

YES : 

The procedure is complete. (If no 

malfunctions are found in all steps, an 
intermittent malfunction is suspected. Refer 
to GROUP 00, How to Use

Malfunction of immobilizer-ECU 

DIAGNOSIS PROCEDURE

STEP 1. Check the MUT-II/III diagnosis code.

Q: Does diagnosis code No.11 reset?

YES : 

Refer to 

P.54A-9

.
