PROCEDURE

1.

INSPECT NO. 1 PARKING BRAKE WIRE ASSEMBLY

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

OK:

The connector is securely connected.

(b) Disconnect the uR2 and u1 No. 1 parking brake wire assembly connectors.

(c) Check both the connector case and the terminals for deformation and corrosion.

OK:

No deformation or corrosion.

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