HARNESS INSPECTION
Check for an open or short circuit in the harness
between the terminals which were faulty according to
the connector measurements. Carry out this
inspection while referring to GROUP 00E, Harness
Connector Inspection
. Here, "Check
harness between power supply and terminal xx" also
includes checking for blown fuse. For inspection
service points when there is a blown fuse, refer to
"Inspection Service Points for a Blown Fuse

MEASURES TO TAKE AFTER REPLACING THE
ECU
If the trouble symptoms have not disappeared even
after replacing the ECU, repeat the inspection
procedure from the beginning.
CONNECTOR MEASUREMENT SERVICE POINTS
Turn the ignition switch to the "LOCK" (OFF) position when
connecting and disconnecting the connectors. Turn the ignition
switch to "ON" when measuring if there are no instructions to
the contrary.
IF INSPECTING WITH THE CONNECTOR CONNECTED
(WITH CIRCUIT IN A CONDITION OF CONTINUITY)
Required Special Tool:
MD998459: Test Harness
Waterproof Connectors
Be sure to use special tool, MB998459. Never insert a test
probe from the harness side, as this so will reduce the
waterproof performance and result in corrosion.
Ordinary (non-waterproof) Connectors
Check by inserting the test probe from the harness side.
Note that if the connector (control unit, etc.) is too small to
permit insertion of the test probe, it should not be forced;
use the backprobing tool for this purpose.

The inspection harness for connector pin contact
pressure should be used. The test probe should never
be forcibly 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.
WARNING
Insert the backprobing tool into connector from
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>
CAUTION
At this time, be careful not to short the connector pins with
the test probes. To do so may damage the circuits inside
the ECU.
Touch the pin directly with the test bar.

CONNECTOR INSPECTION SERVICE POINTS
VISUAL INSPECTION
•
Connector is disconnected or improperly connected
•
Connector pins are pulled out
•
Due to harness tension 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
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.
