Reading and Clearing Diagnostic Trouble Codes

BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: VEHICLE STABILITY CONTROL SYSTEM: DTC CHECK / CLEAR

1. DTC CHECK/CLEAR (When Using the Techstream)

(a) Check for DTCs.

(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) Read the DTCs by following the prompts on the Techstream. Enter the following menus: Chassis / ABS/VSC/TRAC / Trouble Codes.

(6) Check the details of the DTCs Vehicle Stability Control System.

(b) Clear the DTCs.

(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) Operate the Techstream to clear the codes. Enter the following menus: Chassis / ABS/VSC/TRAC / Trouble Codes.

(6) According to the display on the Techstream, select the trouble code data display with the clear button.

(3) Turn the ignition switch to ON.

(4) Observe the blinking pattern of the ABS warning and slip indicator lights in order to identify the DTC.

HINT
If no code is output, inspect the TC and CG terminal circuit and ABS warning light and slip indicator light circuits.





(5) Count the number of blinks of the ABS warning and slip indicator lights.

HINT
* When the system is operating correctly, each light will blink continuously in a pattern of 0.25 seconds on, and then 0.25 seconds off.
* When one DTC is output, each light will output the same code at 4 second intervals (for example, code 21 would be output as 2 flashes, a 1.5-second pause, and then 1 flash).
* When 2 or more DTCs are output, each light will output a different code at 2.5-second intervals, and when all codes have been output, there will be a 4-second pause and the sequence will repeat.
* When multiple codes are stored, they are output in order starting with the lowest DTC number.

(6) The codes are explained in the code table.

ABS DTC





VSC DTC





*1: This DTC is stored when the VSC system detects a malfunction in the ABS.

(7) After completing the check, disconnect terminals 13 (TC) and 4 (CG) of the DLC3 to turn off the display.

If 2 or more DTCs are output at the same time, the DTCs will be output in ascending order.

(b) Clear the DTCs.

(1) Turn the ignition switch off.

(2) Using SST, connect terminals 13 (TC) and 4 (CG) of the DLC3.

(3) Turn the ignition switch to ON.

(4) Clear the DTCs stored in the ECU by depressing the brake pedal 8 times or more within 5 seconds.

(5) Check that the ABS warning and slip indicator lights blink at 0.25 second intervals (0.25 seconds on and 0.25 seconds off).

(6) Turn the ignition switch off.

(7) Remove SST from the terminals of the DLC3.

3. END OF DTC CHECK/CLEAR

(a) Turn the ignition switch to ON.

(b) Check that the ABS warning and slip indicator lights go off within approximately 3 seconds after turning the ignition switch to ON.
