(a) Check for DTCs.

(1) Connect the Techstream to the DLC3.

(2) Turn the ignition switch to ON.

(3) Turn the Techstream on.

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

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

(b) Clear the DTCs.

(1) Connect the Techstream to the DLC3.

(2) Turn the ignition switch to ON.

(3) Turn the Techstream on.

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

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

(2) Turn the ignition switch to ON.

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

HINT
If no code appears, inspect the TC and CG terminal circuit, and ABS warning and SLIP indicator light circuits.





(4) 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, then 0.25 seconds off.
* When one DTC is output, each lamp 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 lamp 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 set, they are output in order starting with the lowest DTC number.

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

ABS DTC









VSC DTC





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

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

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

(b) Clear the DTCs.
