IGNITION COIL CHECK

M1163001201190

Required Special Tool:
MB991958: Scan Tool (M.U.T-III Sub Assembly)

• MB991824: V.C.I.

• MB991827: M.U.T.-III USB Cable

• MB991910: M.U.T.-III Main Harness A

CAUTION

To prevent damage to scan tool MB991958, always turn the 
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
NOTE: It is impossible to carry out an easy check using a cir-
cuit 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.
1. Make sure the diagnosis codes are not stored using scan 

tool MB991958. 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.

2. Disconnect the injector connectors on all of the cylinders.
3. Disconnect the ignition coil connector.
4. Remove the ignition coil and install a good spark plug to the 

ignition coil.

5. Connect the ignition coil connector.
6. Ground the side electrode of the spark plug and crank the 

engine.

7. Check that spark is produced between the electrodes of the 

spark plug.

8. If the spark plug has weak spark or no spark, carry out the 

same check using a good ignition coil. If there is strong 
spark 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 is no spark on this check 
with a good ignition coil, there is probably a problem with the 
ignition circuit. Check the ignition circuit.

9. Using scan tool MB991958, 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.

10.Select "Mode $0A" from "Special Function" of Scan tool 

MB991958. Check whether the permanent-DTC (PDTC) is 
stored or not. <3.0 L Engine>
If stored, clear the PDTC. (Refer to GROUP 13B

CAUTION

To prevent damage to scan tool MB991958, always turn the 
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
11.Disconnect scan tool MB991958 to the data link connector.

SPARK PLUG TEST

M1163001500198

1. Remove the spark plug and connect to the ignition coil.

2. Ground the spark plug outer electrode (body), and crank the 

engine.
Check that there is an electrical discharge between the 
electrodes at this time.

SPARK PLUG CHECK AND CLEANING 

M1163004302735

Required Special Tool
MB992273: Spark Plug Brush

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 MB992273.

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

SPARK PLUG GAP CHECK

Check the plug gap with the wire type plug gauge. Replace it if 
the limit is exceeded.

Standard value:

1.0 

− 1.1 mm (0.039 − 0.043 inch)  <2.4L Engine>

0.7 

− 0.8 mm (0.028 − 0.031 inch)  <3.0L Engine>

Limit:

1.3 mm (0.051 inch)  <2.4L Engine>
0.95 mm (0.037 inch)  <3.0L Engine>

SPARK PLUG INSULATION RESISTANCE CHECK

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 

P.16-46

).

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 recommended 
for the spark plug cleaning.

.

<When a sand blast type plug cleaner is used>

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