Electric Parking Brake Switch Signal Compare Failure
|
DESCRIPTION
When the electric parking brake switch (integration control and panel assembly) is pulled, a lock request signal is sent from the No. 2 skid control ECU (brake actuator assembly) to the parking brake actuator assembly. When the electric parking brake switch (integration control and panel assembly) is pushed, a release request signal is sent from the No. 2 skid control ECU (brake actuator assembly) to the parking brake actuator assembly.

WIRING DIAGRAM
CAUTION / NOTICE / HINT
NOTICE:
-
When the electric parking brake switch (integration control and panel assembly) is pulled and held for 1 second or more without being pulled fully to the lock side, both of the 2 linked contacts may turn OFF causing this DTC to be stored (this is not a system malfunction).
-
To ensure that the electric parking brake does not operate, wait for 3 minutes or more with the ignition switch off, the driver door closed, and the brake pedal not depressed, then disconnect each connector, fuse and relay.
-
After replacing the No. 2 skid control ECU (brake actuator assembly), perform "Calibration".

-
When replacing the No. 2 skid control ECU (brake actuator assembly), operate the electric parking brake switch (integration control and panel assembly) as the parking brake indicator light blinks when the ignition switch is first turned ON.
PROCEDURE
1.
|
READ VALUE USING GTS (EPB SWITCH)
|
(a) Operate the electric parking brake switch (integration control and panel assembly) and check that the value of "EPB Switch" in the Data List changes between Apply and Release in accordance with the operation of the switch.
