NOTE:
Prior to the wiring harness inspection, check key
reminder switch connector C-202, intermediate
connector C-13
connector C-202-1 (terminal 3) and engine-ECU
connector C-127 (terminal 51)
engine-A/T-ECU connector C-128 (terminal 111)
in good condition?
YES :
Go to Step 10.
NO : Repair or replace the damaged
component(s). Confirm that MUT-II/III
communicates normally.
STEP 10. Replace the immobilizer-ECU or
engine-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-20. 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
Troubleshooting/Inspection Service Points −
How to Cope with Intermittent Malfunction
P.00-5).
NO : Replace the engine-ECU

DIAGNOSIS PROCEDURE
STEP 1. Check the fuel gauge circuit.
(1) Disconnect D-13 fuel gauge unit connector.
(2) Connect a test lamp (12 V − 3.4 W) via test
harness (MB991219) between the wiring harness
connector terminals 1 and 2.
(3) Turn the ignition switch to the "ON" position.
Q: Does the test lamp illuminate?
YES :
Go to Step 4.
NO : . Go to Step 2.
STEP 2. Connector check: Combination meter
connector C-06, fuel gauge unit connector D-13
Q: Is combination meter connector C-04, fuel gauge
unit connector D-13 in good condition?
YES :
Go to Step 3.
NO : Repair or replace the damaged
component(s).
STEP 3. Check the wiring harness between
combination meter connector C-06 (terminal 51)
and fuel gauge unit connector D-13 (terminal 1).
