Reading and Clearing Diagnostic Trouble Codes

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

1. DTC CHECK/CLEAR (TECHSTREAM)

(a) Check the DTC.

(1) Connect Techstream to the DLC3.

(2) Turn the engine switch on (IG).

(3) Read the DTCs following the prompts on the tester screen.

(b) Clear the DTC.

(1) Connect Techstream to the DLC3.

(2) Turn the engine switch on (IG).

(3) Operate Techstream to clear the codes.

HINT
Refer to Techstream operator's manual for further details.

2. DTC CHECK/CLEAR (SST CHECK WIRE)

(a) Check the DTC.





(1) Using SST, connect terminals TC and CG of the DLC3.

SST : 09843-18040

(2) Turn the engine switch on (IG).

(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 lights circuits.





(4) Count the number of blinks of the ABS warning and SLIP indicator lights.

HINT
* How to read DTCs:
Diagnostic trouble codes are represented by the number of blinks of a warning light. For example, code21 would be shown by 2 blinks, a pause of 1.5 seconds, and then 1 blink.
* If one code is detected:
The light repeats the same code after a pause of 4 seconds.
* If multiple codes are detected:
The light outputs one code after another with a 2.5-second pause between each code. When all codes have been output, there is a 4-second pause and then the light begins to output the codes again.

(5) Codes are explained in the code table Vehicle Stability Control System.

(6) After completing the check, disconnect terminals TC and CG of the DLC3, and 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 DTC.

(1) Using SST, connect terminals TC and CG of the DLC3.





SST : 09843-18040

(2) Turn the engine switch on (IG).

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





(4) Check that the warning light indicates a normal system code.

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

HINT
Clearing the DTCs cannot be performed by disconnecting the battery terminal or the ECU-IG NO. 2 fuse.

3. END OF DTC CHECK/CLEAR

(a) Turn the engine switch on (IG).

(b) Check that the ABS warning and SLIP indicator lights goes off within approximately 3 seconds.
