CONNECTOR CONSTRUCTION
The connector of the SRS diagnosis unit has a double lock
mechanism, fit verification mechanism and connector shorting
mechanism.
DOUBLE LOCK MECHANISM
The mechanism is composed of two mechanisms: each con-
nector of the SRS diagnosis unit is locked to the connector
of the harness, then these connectors (of the four harnesses)
are locked with the secondary lock lever mounted on the
connector of the SRS diagnosis unit side.
The secondary lock lever locking is done as the lock spring
fits in the notch of the connector.
The operating principle is described below.
When Connectors Are To Be Fitted
(1) The SRS diagnosis unit and harness side connectors
are connected. (Primary lock)
(2) The secondary lock lever mounted to the SRS diagnosis
unit side connector, is pressed down until a click is heard
indicating that the connectors have been locked. (Second-
ary lock)
If the harness and SRS diagnosis unit connectors do
not properly fit, the secondary lock lever side projection
and the harness side connector projection interfere with
each other, making it impossible to lock the connectors.
When Connectors Are Unlocked
(1) Release the lock of SDU connector in accordance with
the following procedure:
In case that there is no notch on the lock lever
Place a flat tip screwdriver against the lock spring (metal
section) of the connector lock lever as shown in the illustra-
tion, and push the spring horizontally toward the inside
of the unit.
Caution
1. Do not use excessive force to raise the lock lever.
2. Do not insert the screwdriver into the gap between
the lock lever and the lock spring.
In case that there is a notch on the lock lever
Place a flat tip screwdriver against the lock spring (metal
section) at the lock lever notch as shown in the illustration,
and push the spring toward the unit.
Caution
Do not use excessive force to raise the lock lever.
(2) Press the primary lock of each of the harness side
connectors and remove the harness side connector.
