CAUTION / NOTICE / HINT

NOTICE:
·

The electric parking brake may still operate up to 4 minutes after the ignition switch is turned off. Before disconnecting connectors or fuses, turn the ignition switch off and wait 4 minutes or more.

·

After replacing the skid control ECU (brake actuator assembly), perform acceleration sensor zero point calibration and store system information memorization.

2.CHECK HARNESS AND CONNECTOR (SKID CONTROL ECU (BRAKE ACTUATOR ASSEMBLY) - ELECTRIC PARKING BRAKE SWITCH (ELECTRIC PARKING BRAKE SWITCH 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 I207 electric parking brake switch (electric parking brake switch assembly) connector.


c.

Disconnect the A151 skid control ECU (brake actuator assembly) connector.
