Brake/EPB A

PROCEDURE

1.CHECK HARNESS AND CONNECTOR (SENSOR POWER SOURCE CIRCUIT)

Procedure1

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.



Pre-procedure1

b.

Disconnect the k2 rear speed sensor LH connector.


Procedure2

c.

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

OK:

No deformation or corrosion.



Pre-procedure2

d.

Turn the ignition switch to ON.


Procedure3

e.

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

Standard Voltage:
Tester Connection Condition Specified Condition
