PROCEDURE

1.INSPECT NO. 1 PARKING BRAKE WIRE ASSEMBLY

Pre-procedure1

a.

Turn the ignition switch off.


Procedure1

b.

Make sure that there is no looseness at the locking part and the connecting part of the connectors.

OK:

The connector is securely connected.



Pre-procedure2

c.

Disconnect the jK1 and j1 No. 1 parking brake wire assembly connectors.


Procedure2

d.

Check both the connector case and the terminals for deformation and corrosion.

OK:

No deformation or corrosion.



Procedure3

e.

Measure the resistance according to the value(s) in the table below.
