ZC501908

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.

 

CONNECTOR ENGAGEMENT INSPECTION

Required Special Tool:

MB991219: Inspection Harness (contained in MB991223 Test
Harness)

ZC501916

MB991219

0000

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

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.
