Toyota CH-R Service Manual: Test Mode Procedure

When Using the Techstream:

1. Turn the ignition switch off.
2. Connect the Techstream to the DLC3.
3. Turn the ignition switch to ON.
4. Turn the Techstream on.
5. Enter the following menus: Chassis / ABS/VSC/TRAC/EPB / Utility / Check Mode
6. Follow the Techstream display and select "Next".
7. Push and hold the electric parking brake switch (electric parking brake switch assembly) to the release side for 5 seconds or more.

   NOTICE:

   • Make sure to perform this procedure with the ignition switch to ON.
   • Make sure that the brake pedal is not depressed when performing this procedure.
   • When the system changes to pad replacement mode, DTC C13A7/43 may be stored. If the DTC is stored, clear the DTCs after the procedure (rear brake pad replacement, etc.) is complete.

   HINT:

   The parking brake indicator light flashes (red) (0.25 second intervals). After a short time, the parking brake actuator assembly operates (if the parking brake is engaged, the motor will operate to disengage the parking brake, and then will operate again). Once the parking brake actuator assembly is in the pad replacement position, the parking brake indicator light flashes (red) (1 second intervals).

When not Using the Techstream:

1. Turn the ignition switch off.
2. Turn the ignition switch to ON.
3. Within 8 seconds, operate the electric parking brake switch (electric parking brake switch assembly) to perform 3 lock side ON operations (from off (release) to on (pull)) and then 3 release side ON operations (from off (release) to on (push)).

   NOTICE:

   • If the operation is performed too quickly, the system may not respond. If the system does not respond, perform the operation again at a slower speed.
   • The parking brake must be released.

   HINT:

   The parking brake indicator light (red) flashes (0.25 second intervals).

4. Push and hold the electric parking brake switch (electric parking brake switch assembly) to the release side for 5 seconds or more.

   NOTICE:

   • Make sure to perform this procedure with the ignition switch to ON.
   • Make sure that the brake pedal is not depressed when performing this procedure.
   • When the system changes to pad replacement mode, DTC C13A7 may be stored. If the DTC is stored, clear the DTCs after the procedure (rear brake pad replacement, etc.) is complete.

   HINT:

   After a short time passes, the parking brake actuator assembly operates (if operated from the parking brake locked condition, the motor of the parking brake actuator assembly is temporarily stopped after being operated, and then operation starts again), and once the assembly finishes operating, the parking brake indicator light (red) flashes slowly (1 second intervals). (Nut moves back inside the cylinder and system enters pad replacement mode).

When Using the Techstream:

1. Disconnect the Techstream from the DLC3.

NOTICE:

• When performing work (replacing the rear brake pad, etc.), do not operate the electric parking brake switch (electric parking brake switch assembly) or turn the ignition switch to ON and operate the shift lever. If the electric parking brake switch (electric parking brake switch assembly) or shift lever is operated, the parking brake may operate and the rear disc brake piston may fall off. Also, make sure to disconnect the connector of the parking brake actuator assembly or disconnect the cable from the negative (-) battery terminal.
• When DTC C13A7 is stored, clear the DTCs.
