Oil and Chemical Type

Caution

• When replacing the DSC HU/CM, perform the configuration to assure that the system operates correctly. (See CONFIGURATION.)

• The internal parts of the DSC HU/CM could be damaged if dropped. Be careful not to drop the DSC HU/CM. Replace the DSC HU/CM if it is subjected to an impact.

• Brake fluid will damage painted surfaces. Be careful not to spill any on painted surfaces. In addition, if there is any brake fluid on the wiring harness, the wire insulation may corrode causing a malfunction such as a short circuit. If brake fluid gets on a painted surface or wiring harness, wash and flush it off completely with water immediately.

Note

• The DSC HU/CM records the vehicle specification information and the electric parking brake operation/release condition.

• Tighten the brake pipe flare nut using any commercially available flare nut wrench.

2)Switch the ignition OFF and wait for 3 s or more.

3)Switch the ignition ON (engine off or on) again and wait for 3 s or more.

(4)Clear the DTC. (See CLEARING DTC.)

(5)Perform the sensor initialization for the DSC-related parts. (See DSC RELATED PARTS SENSOR INITIALIZATION PROCEDURE [(US)].)

(6)Check the related parts using the following procedure.

1)Operate the electric parking brake.

2)Release the electric parking brake.

3)Operate the electric parking brake.

4)Release the electric parking brake.

(7)Clear the DTC. (See CLEARING DTC.)

• If the warning/indicator lights do not turn off, perform a DTC inspection. (See DTC INSPECTION.)

(9)Operate the electric parking brake.

(10)Verify that the electric parking brake indicator light turns on and the brake control system warning light turns off.

• If the electric parking brake indicator light does not turn on, the electric parking brake indicator light flashes, or the brake control system warning light does not turn off, perform a DTC inspection as a malfunction of the electric parking brake may have occurred. (See DTC INSPECTION.)
