IGNITION COIL CHECK

M1163001201554

NOTE: It is impossible to carry out an easy check
using a circuit tester because a diode and so on are
integrated into the inside circuit of this ignition coil.
Accordingly, check the ignition coil in the following
procedure.

CAUTION

For vehicles with CAN

harness A to send simulated
vehicle speed. If you connect
M.U.T.-III main harness B instead,
the CAN communication does not
function correctly.

1. Turn the ignition switch to the "LOCK" (OFF)

position, and then connect the M.U.T.-III to the
diagnosis connector.

2. Make sure the diagnosis codes are not stored

using M.U.T.-III. If stored, record the code No.
Carry out the troubleshooting for the stored codes
and solve the problems even if not related to the
ignition.

3. Disconnect the injector connectors on all of the

cylinders.

4. Disconnect the ignition coil connector.

5. Remove the ignition coil and install a good spark

plug to the ignition coil.

6. Connect the ignition coil connector.

7. Earth the side electrode of the spark plug and

crank the engine.

8. Check that spark is produced between the

electrodes of the spark plug.

9. If the spark plug has weak sparks or no sparks,

carry out the same check using a good ignition
coil. If there are strong sparks on this check with a
good ignition coil, it becomes clear there is a
problem with the ignition coil. Replace the ignition
coil with a new one. If there are no sparks on this
check with a good ignition coil, there is probably a
problem with the ignition circuit. Check the ignition
circuit.

10.Using M.U.T.-III, make sure whether the diagnosis

codes are stored due to the check, or not. Except
the codes stored in Step 1, clear the codes all
together if they are present. And then, carry out
the troubleshooting about the codes recorded.

11.Turn the ignition switch to the "LOCK" (OFF)

position, and then disconnect the M.U.T.-III.

SPARK PLUG CHECK AND CLEANING

M1163004302898

CAUTION

• Never attempt to adjust the gap of the iridium

plug.

• Do not attempt to clean the iridium plug using

a wire brush because it may result in damage
to the electrode. When the iridium plug is
cleaned, use a plug cleaner, sand blast type,
or special tool spark plug brush (MB992273).

NOTE: Obey the maintenance interval of the vehicle
for the spark plug replacement. If the plug gap and
insulation resistance are normal, check the plug state
and clean it if necessary.

SPARK PLUG INSULATION RESISTANCE
CHECK

AK503737

1. Measure the insulation resistance of the spark

plug. If the insulation resistance of the spark plug
is under the limited value, clean the spark plug
(Refer to ).

2. After cleaning, measure the insulation resistance

again. Replace the plug unless it is within the
limited value.

Limit: Minimum 10 M

Ω

SPARK PLUG CLEANING

NOTE: Using a sand blast type plug cleaner, is rec-
ommended for the spark plug cleaning.

Cleaning must be carried out within 20 seconds to
protect the electrode.

1. Sufficiently apply the brake cleaner to the plug

end.

NOTE: Repeatedly applying the brake cleaner is
acceptable during the cleaning.

AK705045

MB992273

2. Using special tool spark plug brush (MB992273),

intensively clean the electrode for 1 to 2 minutes.

NOTE: Even if using strong force, the electrode is
not damaged.

NOTE: In case of insufficient cleaning, it is per-
missible to take longer than 2 minutes for clean-
ing.

3. After the cleaning, sufficiently remove and then

dry both of the carbon and the brake cleaner on
the plug, using a waste cloth or air blowing.

CAMSHAFT POSITION SENSOR CHECK

M1163004401074

Check the camshaft position sensor circuit if
self-diagnosis code, No.P0340 is shown.

(Refer to GROUP 13A

− Troubleshooting − Inspec-

tion procedure for diagnosis code

− Code No. P0340

camshaft position sensor system .)

CRANK ANGLE SENSOR CHECK

M1163004501123

Check the crank angle sensor circuit if self-diagnosis

code, No.P0335 is shown.
