When removing or installing the rear disc brake caliper assembly, pushing back the disc brake piston may cause a large clearance between the brake pads and brake disc. When the brake pedal is depressed with a large clearance between the brake pads and the brake disc, DTC C140000 and/or C140A00 related to abnormal brake fluid pressure may be stored. Make sure to clear any DTCs after performing this procedure.
While the auxiliary battery is connected, even if the power switch is off, the brake control system activates when the brake pedal is depressed or any door courtesy switch turns on. Therefore, when servicing the brake system components, do not operate the brake pedal or open/close the doors while the auxiliary battery is connected.
Use the same procedure for the RH and LH sides.
The following procedure is for the LH side.
If the rear speed sensor rotor needs to be replaced, replace the rear axle hub and bearing assembly.
The rear speed sensor is a component of the rear axle hub and bearing assembly. If the rear speed sensor is malfunctioning, replace the rear axle hub and bearing assembly.
1. PRECAUTION
After the ignition switch is turned off, there may be a waiting time before disconnecting the negative (-) auxiliary battery terminal. (for HV Model)
