WIRING DIAGRAM
CAUTION / NOTICE / HINT
- NOTICE:
- ·
Although DTC C06132A may be stored after entering pad replacement mode, this is not a malfunction.
·Although DTC C06132A may be stored after forcibly releasing the parking brake, this is not a malfunction.
·The electric parking brake may still operate up to 20 seconds after the ignition switch is turned off. Before disconnecting connectors or fuses, turn the ignition switch off and wait 20 seconds 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 (integration control and panel assembly) as the parking brake indicator light blinks when the ignition switch is first turned to ON.
PROCEDURE
Using the GTS, check for DTCs other than DTC C06132A.

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 MM3 and M49 No. 1 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.

Turn the ignition switch off.
Make sure the No. 1 parking brake wire assembly is securely installed.
Disconnect the A39 skid control ECU (brake actuator assembly) connector.
Disconnect the M49 parking brake actuator assembly RH connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition A39-2 (MRR+) - M49-2 (MRR+) Always Below 1 Ω A39-3 (MRR-) - M49-1 (MRR-) Always Below 1 Ω A39-2 (MRR+) or M49-2 (MRR+) - Body ground Always 10 kΩ or higher A39-3 (MRR-) or M49-1 (MRR-) - Body ground Always 10 kΩ or higher
- Result:
Proceed to OK NG

Enter rear brake pad replacement mode.
Turn the ignition switch off.
Check that the rotating parts are not seized or the actuator is not spinning freely.
Check that the parking brake actuator assembly RH is installed properly to the rear brake caliper and that it is not spinning freely.
For the parking brake actuator assembly RH removal procedure: Click hereBrake>PARKING BRAKE>ELECTRIC PARKING BRAKE ACTUATOR>REMOVAL201910,999999,_54,_083081,_0403275,RM100000001JQVX,
Check that there is no damage to the rotating parts from the parking brake actuator assembly RH to the rear brake caliper.
Inspect the parking brake actuator assembly RH 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 GTS.
- HINT:
-
Return to normal mode after work is complete.
