Reading and Clearing Diagnostic Trouble Codes

BRAKE CONTROL: ELECTRONICALLY CONTROLLED BRAKE SYSTEM: DTC CHECK / CLEAR

1. DTC CHECK/CLEAR (WHEN USING TECHSTREAM)

(a) DTC check

(1) Connect the Techstream to the DLC3.

(2) Turn the power switch ON (IG).

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

(b) DTC clear

(1) Connect the Techstream to the DLC3.

(2) Turn the power switch ON (IG).

(3) Operate the Techstream to clear the codes.

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

2. DTC CHECK/CLEAR (WHEN USING SST CHECK WIRE)

(a) DTC check





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

SST : 09843-18040

(2) Turn the power switch ON (IG).

(3) Read DTC from the ABS warning light, brake warning light / yellow (minor malfunction), slip indicator light and brake hold standby indicator light on the combination meter and multi-information display.

HINT
* When the system is normal, the relevant light turns on for 0.25 seconds and off for 0.25 seconds and repeats this pattern.
* When only 1 DTC is stored, the relevant light outputs the same code after an interval of 4 seconds. Example: When DTC 42 is stored, the light blinks 4 times, turns off for 1.5 seconds, blinks twice, turns off for 4 seconds, and then repeats this output pattern.
* When 2 or more DTCs are stored, the relevant light outputs the codes with an interval of 2.5 seconds between each different code, and the output of all codes repeats after an interval of 4 seconds.
* If no code appears, inspect the TC and CG terminal circuit, ABS and brake warning light / yellow (minor malfunction) warning light circuits and brake hold standby and slip indicator light circuits.





(4) As an example, the illustration below shows the blinking patterns of the normal system code and trouble codes 31 and 43, and display of the normal system code and trouble code 31 on the multi-information display.

(5) The codes are explained in the DIAGNOSTIC TROUBLE CODE CHART Electronically Controlled Brake System.

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

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

(b) DTC clear

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





SST : 09843-18040

(2) Turn the power 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 ABS warning light, brake warning light / yellow (minor malfunction), slip indicator light, brake hold standby indicator light and multi-information display indicate the normal system code.

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

3. END OF DTC CHECK/CLEAR (WHEN USING SST CHECK WIRE)

(a) Turn the power switch ON (IG).

(b) Check that the ABS warning light, brake warning light / yellow (minor malfunction), slip indicator light and brake hold standby indicator light illuminate. After the power switch is turned ON (READY), check that they turn off.
