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 YK1 and Y4 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.
