B0M0014A

Connectors equipped with shock protectors must be
checked with a mini probe (thin), or it will be necessary to
remove the shock protector.
B0M0015A

When the connector has a back plate, remove the plate
after removing the projection of the plate first. (Be careful not
to use excessive force, since the terminals might brake off.)
B0M0016A
C: CHECKING FOR POOR CONTACT ON
PLUG-IN CONNECTORS
1. POOR CONTACT
Poor contact is frequently caused by corroded terminals, dirt,
foreign substances, weak contact points between male and
female connectors, etc. Quite often a plug with poor contact
will work perfectly again after it has been pulled off and recon-
nected. If harness and connector checks do not reveal any
defect, it can be assumed that an intermittent contact in a
connector is the source of trouble.
B0M0017A
2. VISUAL INSPECTION
1) Disconnect the two connector halves.
2) Check the connector pins for signs of corrosion or foreign
material.
3) Check the connector for loose and damaged terminals,
and make sure they are set correctly in the connector.
NOTE:
When the harness is pulled lightly, the terminals should not
come out.
B0M0018A
4) Insert the male pin of the connector into the female pin,
then pull it out.
NOTE:
If one of the pins allows to pull out easily, it is a likely source
of a malfunction.
