Q: Are the harness wires between immobilizer-ECU
connector C-207-1 (terminal 3) and engine-ECU
connector C-117 (terminal 98) in good condition?
YES :
Go to Step 10.
NO :
Repair or replace the damaged
component(s). Confirm that M.U.T.-II/III
communicates normally.

STEP 10. Replace the immobilizer-ECU or
engine-ECU.
Replace the immobilizer-ECU.
Q: Did the communication with M.U.T.-II/III become
possible after replacing the immobilizer-ECU?
YES :
Register the password (secret code) and
encrypted code
. Confirm that
M.U.T.-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
).
NO :
Replace the engine-ECU.
INSPECTION PROCEDURE 2: The Ignition Key cannot be Registered.
TECHNICAL DESCRIPTION (COMMENT)
The ignition key transponder or the immobilizer-ECU
is suspected to be defective.
TROUBLESHOOTING HINTS
• Malfunction of the ignition key
• Malfunction of immobilizer-ECU
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-II/III diagnosis code.
Q: Does diagnosis code No.11 reset?
YES :
Refer to
.
NO :
Replace the ignition key that cannot be
registered. Then re-register the encrypted
code. (Refer to
). Verify that the
ignition key can be registered, then Go to
Step 2.
STEP 2. Retest the system.
Q: Does registered ignition key function properly?
YES :
The procedure is complete.
NO :
Replace the immobilizer-ECU.
INSPECTION PROCEDURE 3: Engine does not Start (Cranking but no Initial Combustion).
TECHNICAL DESCRIPTION (COMMENT)
If the fuel injectors are not operating, there might be
a problem with the MPI system in addition to a mal-
function of the immobilizer system. It is normal for
this to occur if an attempt is made to start the engine
using a key that has not been properly registered.
TROUBLESHOOTING HINTS
• Malfunction of MPI system
• Malfunction of immobilizer-ECU
DIAGNOSIS PROCEDURE
STEP 1. Check the system voltage.
Measure the system voltage during cranking.
Q: Is the voltage 8 volts or more?
YES :
Go to Step 2.
NO :
Check the battery. Refer to
. The
engine should start.
