SRS-ECU harness
connector
0000
Since the SRS-ECU harness connector is plated to
improve conductivity, observe the warning below when
checking this connector.
Insert the backprobing tool into the connector from
the harness side, and connect the tester to the
backprobing tool. If any tool other than the
backprobing tool is used, it may cause damage to the
harness and other components. Furthermore,
measurement should not be carried out by touching
the backprobing tool directly against the terminals
from the front of the connector. The terminals are
plated to increase their conductivity, so that if they
are touched directly by the backprobing tool, the
plating may break, which will decrease reliability.

When Inspecting a Male 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 PIN INSPECTION
ZC5019110000
If the connector pin stopper is damaged, the terminal
connections (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.

HOW TO COPE WITH INTERMITTENT
MALFUNCTIONS
M10001000139USA0000010000
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 most likely.

3. USE SIMULATION TEST
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 condition 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.
