DIAGNOSIS FUNCTION

M1001013401040

The diagnosis function retrieves diagnosis code and 
data list by M.U.T.-III and enables the performance of 
the actuator test.

• DIAGNOSIS CODE

• Data list output

• Actuator test

• Diagnosis deletion using M.U.T.-III

• Freeze frame data

• Status indication by diagnosis code

• ECU information display

NOTE: If a diagnosis code is set, the "status indica-
tion by diagnosis code" informs users whether a 
mechanical problem currently exists (current trouble) 
or whether it existed before but normal operation has 
been restored (past trouble).

 HOW TO READ DIAGNOSIS CODE

CAUTION

Before connecting or disconnecting the 
M.U.T.-III, turn the ignition switch to the "LOCK" 
(OFF) position.

Diagnosis connector

Connect the M.U.T.-III to the 16-pin diagnosis con-
nector, and read the diagnosis code.

NOTE: 

.

For details on how to use the M.U.T.-III, refer to 
the "M.U.T.-III operation manual."

1. Ensure that the ignition switch is at the "LOCK" 

(OFF) position.

2. Start up the personal computer.

3. Connect special tool V.C.I.-Lite USB cable 

(MB992747/MB992748) or M.U.T.-III USB cable 
(MB991827) to V.C.I.-Lite (MB992744) or V.C.I. 
(MB991824) and the personal computer.

4. Connect V.C.I.-Lite main harness A (MB992745) 

or M.U.T.-III main harness A (MB991910) to the 
V.C.I.-Lite or V.C.I.

5. Connect the V.C.I.-Lite main harness A or 

M.U.T.-III main harness A to the diagnosis 
connector of the vehicle.

NOTE: When the V.C.I.-Lite is connected to the 
diagnosis connector, the V.C.I.-Lite indicator lamp 
will be illuminated in a green colour.

6. Turn the V.C.I. power switch to the "ON" position. 

<When using the V.C.I.>

NOTE: When the V.C.I. is energized, the V.C.I. 
indicator lamp will be illuminated in a green col-
our.

7. Start the M.U.T.-III system on the personal 

computer and turn the ignition switch to the "ON" 
position.

8. Read the diagnosis code.

9. Disconnecting the M.U.T.-III is the reverse of the 

connecting sequence, making sure that the 
ignition switch is at the "LOCK" (OFF) position.

ERASING DIAGNOSIS CODE

CAUTION

Before connecting or disconnecting the 
M.U.T.-III, turn the ignition switch to the "LOCK" 
(OFF) position.
Connect the M.U.T.-III to the diagnosis connector, 
and erase the diagnosis code. The procedure is the 
same as "How to Read Diagnosis Code ."

HOW TO USE THE INSPECTION 
PROCEDURES

M1001013500862

The causes of many of the problems occurring in electric circuitry are generally the connectors, components, 
the ECU, the wiring harnesses between connectors, in that order. These inspection procedures follow this 
order. They first try to discover a problem with a connector or a defective component.

CURRENT TROUBLE

Indicates that the status is "Active" and the trouble is 
currently present. Carry out troubleshooting as 
described in the applicable inspection procedure.

HOW TO USE TROUBLESHOOTING/INSPECTION SERVICE POINTS

GENERAL

00-9

PAST TROUBLE

Indicates that the status is "Stored" and the trouble is 
historic. Since the trouble may still be present, set 
the vehicle to the diagnosis code detection condition 
and check that the status changes to "Active". If the 
status does not change from "Stored", observe the 
applicable inspection procedure with particular 
emphasis on connector(s) and wiring harness.

HARNESS CHECK

Check for an open or short circuit in the harness 
between the terminals which are faulty according to 
the connector measurements. Carry out this inspec-
tion while referring to the Electrical Wiring Manual. 
Here, "Check the wiring harness between the power 
supply and terminal xx" also includes checking for 
blown fuse. For inspection service points when there 
is a blown fuse, refer to "Inspection Service Points 
for a Blown Fus

P.00-11

."

MEASURES TO TAKE AFTER REPLAC-
ING THE ECU

If the trouble symptoms have not disappeared even 
after replacing the ECU, repeat the inspection proce-
dure from the beginning.

CONNECTOR MEASUREMENT SERVICE 
POINTS

M1001013600405

CAUTION

During diagnosis, a diagnosis code associated 
with other system may be set when the ignition 
switch is turned on with connector(s) discon-
nected. On completion, confirm all systems for 
diagnosis code(s). If diagnosis code(s) are set, 
erase them all.
Turn the ignition switch to the "LOCK" (OFF) position 
when connecting and disconnecting the connectors. 
Turn the ignition switch to "ON" when measuring, 
unless there are instructions to the contrary.

IF INSPECTING WITH THE CONNECTOR 
CONNECTED <WATERPROOF 
CONNECTORS>

CAUTION

Never insert a test probe from the harness side, 
as this will reduce the waterproof performance 
and result in corrosion.

AC105597AB

Special tool

Use the special tools such as test harness, harness 
connector or check harness.

IF INSPECTING WITH THE CONNECTOR 
CONNECTED <ORDINARY 
(NON-WATERPROOF) CONNECTORS>

AC105598AH

MB992006

Inspect by inserting a test probe from the harness 
side. If the connector is too small to insert a test 
probe (e.g. control unit connector), do not insert it 
forcibly. Use special tool extra fine probe 
(MB992006).
