IF INSPECTING WITH THE CONNECTOR
DISCONNECTED FEMALE PIN>
Required Special Tool:
MB991219: Inspection Harness (Included in MB991223,
Harness Set)
The special tool MB991219 for connector pin contact pres-
sure should be used. The test probe should never be forc-
ibly inserted, as it may cause a defective contact.
From back side of the connector (SRS-ECU harness side
connector)
Since the SRS-ECU harness connector is plated to improve
conductivity, observe the warning below when checking this
connector.
Insert the test probe tool into the connector from the
harness side, and connect the tester to the test probe
tool. If any tool other than the test probe tool is used,
it may cause damage to the harness and other com-
ponents. Furthermore, measurement should not be
carried out by touching the test probe tool directly
against the terminals from the front of the connector.
The terminals are plated to increase their conductiv-
ity, so that if they are touched directly by the test
probe tool, the plating may break, which will decrease
reliability.
IF INSPECTING WITH THE CONNECTOR
DISCONNECTED PIN>
At this time, be careful not to short the connector pins with
the test probes. Doing so may damage the circuits inside
the ECU.
Touch the pin directly with the test probe.

CONNECTOR INSPECTION SERVICE POINTSM1001013700060
VISUAL INSPECTION
Connector is disconnected or improperly connected
Connector pins are pulled out
Stretched an broken wires at terminal section
Low contact pressure between male and female terminals
Low connection pressure due to rusted terminals or foreign
matter lodged in terminals
.
CONNECTOR PIN INSPECTION
If the connector pin stopper is damaged, the terminal connec-
tions (male and female pins) will not be perfect even when the
connector body is connected, because the pins may pull out of
the back side of the connector. Therefore, gently pull the wires
one by one to make sure that no pins pull out of the connector.

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
M1001013900064
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 condi-
tions like vibration, temperature and/or moisture change, poor
connections. From the customer's responses, it should be rea-
soned which condition is most likely.
.
3. USE SIMULATION TEST
Use the simulation tests below to attempt to duplicate the cus-
tomer's complaint. Determine the most likely circuit(s) and per-
form 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 condition related intermittent
malfunctions, try to change the conditions of the suspected cir-
cuit components, then use the simulation tests below.
.

4. VERIFY THE INTERMITTENT MALFUNCTION IS
ELIMINATED
Repair the malfunctioning part and try to duplicate the condi-
tion(s) again to verify the intermittent malfunction has been
eliminated.
.
SIMULATION TESTS
NOTE: In case of difficulty in finding the cause of the intermit-
tent malfunction, the data recorder function in the
DIAGNOSTIC TOOL (MUT-III) is effective.
For these simulation tests, shake, then gently bend, pull, and
twist the wiring of each of these examples to duplicate the inter-
mittent malfunction.
Shake the connector up-and-down, and right-and-left.
Shake the wiring harness up-and-down, and right-and-left.
Especially, check the splice points of wiring harnesses care-
fully. Refer to GROUP 00E, Harness Connector Inspection
P.00E-2.
Shake the part or sensor.

INSPECTION SERVICE POINTS FOR A BLOWN
FUSE
M1001013800067
Remove the blown fuse and measure the resistance between
the load side of the blown fuse and the ground. Close the
switches of all circuits which are connected to this fuse. If the
resistance is almost 0
at this time, there is a short some-
where between these switches and the load. If the resistance is
not 0
, there is no short at the present time, but a momentary
short has probably caused the fuse to blow.
The main causes of a short circuit are the following.
Harness being clamped by the vehicle body
Damage to the outer casing of the harness due to wear or
heat
Water getting into the connector or circuitry
Human error (mistakenly shorting a circuit, etc).
HOW TO TREAT CURRENT TROUBLEM1001014000020
1. Make a note of the diagnostic trouble code, and erase it.
2. Check the trouble symptom again.
3. Check for diagnostic trouble codes again.
4. If a diagnostic trouble code is set, follow the applicable
Diagnostic Trouble Code Chart.
5. If no diagnostic trouble code is set, refer to "How to Cope
with Intermittent Malfunction P.00-14."
HOW TO TREAT PAST TROUBLEM1001014100050
1. Establish from the customer whether a fuse or connector
has been replaced or disconnected.
2. If yes, erase the diagnostic trouble code, and then check
that no diagnostic code is reset. If no diagnostic trouble
code is reset, the diagnosis is complete.
3. If no, follow the applicable Diagnostic Trouble Code Chart.
Then check the wiring harness and connector, and refer to
"How to Cope with Intermittent Malfunction P.00-14."

AFFILIATED DTC REFERENCE TABLEM1001013000027
For vehicles with CAN, when DTC which influences
the transmission data is set to the ECU which sends
the data, DTC also could be set to the ECU which
receives and controls the transmission data. The
table below shows the relativity of DTC between
ECUs.
