CONNECTOR ENGAGEMENT INSPECTION
Required Special Tool:
MB991219: Inspection Harness (contained in MB991223 Test
Harness)
Use special tool, MB991219 to inspect the engagement of the
male pins and female pins. [Pin drawing force: 1 N (0.2 pound)
or more]
HOW TO COPE WITH INTERMITTENT
MALFUNCTIONS
Most intermittent malfunctions occur under certain
conditions. If those conditions can be identified, the
cause will be easier to find.
TO COPE WITH INTERMITTENT MALFUNCTION;
1. Ask the customer about the malfunction
Ask what it feels like, what it sounds like, etc. Then
ask about driving conditions, weather, frequency of
occurrence, and so on.
2. Determine the conditions from the customer's
responses
Typically, almost all intermittent malfunctions occur
from conditions like vibration, temperature and/or
moisture change, poor connections. From the
customer's responses, it should be reasoned which
condition is influenced.
3. Use simulation test
In the cases of vibration or poor connections, use the
simulation tests below to attempt to duplicate the
customer's complaint. Determine the most likely
circuit(s) and perform the simulation tests on the
connectors and parts of that circuit(s). Be sure to use
the inspection procedures provided for diagnostic
trouble codes and trouble symptoms.
For temperature and/or moisture conditions related
intermittent malfunctions try to change the conditions
of the suspected circuit components, then use the
simulation tests below.
4. Verify the intermittent malfunction is
eliminated
Repair the malfunctioning part and try to duplicate
the condition(s) again to verify the intermittent
malfunction has been eliminated.
SIMULATION TESTS
NOTE: In case of difficulty in finding the cause of the
intermittent malfunction, the data recorder function in the scan
tool is effective.
