WIRING DIAGRAM
CAUTION / NOTICE / HINT
- NOTICE:
- ·
Although DTC C060E2A may be stored after entering pad replacement mode, this is not a malfunction.
·Although DTC C060E2A may be stored after forcibly releasing the parking brake, this is not a malfunction.
·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.
·When replacing the skid control ECU (brake actuator assembly), operate the electric parking brake switch (electric parking brake switch assembly) as the parking brake indicator light (red) blinks when the ignition switch is first turned ON.
PROCEDURE
Using the GTS, check for DTCs other than DTC C060E2A.

Turn the ignition switch off.
Make sure that there is no looseness at the locking part and the connecting part of the connectors.
- OK:
The connector is securely connected.
Disconnect the nO3 and n1 No. 2 parking brake wire assembly connectors.
Check both the connector case and the terminals for deformation and corrosion.
- OK:
No deformation or corrosion.
Measure the resistance according to the value(s) in the table below.

| *c | (to Parking Brake Actuator Assembly LH) | - | - |
- Standard Resistance:
Tester Connection Condition Specified Condition nO3-1 - n1-2 (MRL+) Always Below 1 Ω nO3-1 or n1-2 (MRL+) - Body ground and other terminals Always 10 kΩ or higher nO3-2 - n1-1 (MRL-) Always Below 1 Ω nO3-2 or n1-1 (MRL-) - Body ground and other terminals Always 10 kΩ or higher
- Result:
Proceed to OK NG

Turn the ignition switch off.
Make sure the No. 2 parking brake wire assembly is securely installed.
Disconnect the A151 skid control ECU (brake actuator assembly) connector.
Disconnect the n1 parking brake actuator assembly LH connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition A151-13 (MRL+) - n1-2 (MRL+) Always Below 1 Ω A151-12 (MRL-) - n1-1 (MRL-) Always Below 1 Ω A151-13 (MRL+) or n1-2 (MRL+) - Body ground Always 10 kΩ or higher A151-12 (MRL-) or n1-1 (MRL-) - Body ground Always 10 kΩ or higher
- Result:
Proceed to OK NG
OK

Enter rear brake pad replacement mode.
Turn the ignition switch off.
Check that the rotating parts are not seized and the actuator is not spinning freely.
Check that the parking brake actuator assembly LH is installed properly to the rear brake caliper and that it is not spinning freely.
For the parking brake actuator assembly LH removal procedure:
Check that there is no damage to the rotating parts from the parking brake actuator assembly LH to the rear brake caliper.
Inspect the parking brake actuator assembly LH and check that it operates correctly.
Check that the rear brake caliper threaded part rotates and that the rear disc brake piston moves outward.
- HINT:
-
For the check procedures, refer to the parking brake forced release method when not using the SST.
- HINT:
-
Return to normal mode after work is complete.
- Result:
Result Proceed to Parking brake actuator assembly LH is malfunctioning A Other than parking brake actuator assembly LH is malfunctioning B
