Vehicle Stability Control System (for BOSCH Made)

BRAKE CONTROL: VEHICLE STABILITY CONTROL SYSTEM (for BOSCH Made): DTC CHECK / CLEAR

1. DTC CHECK/CLEAR (When not Using the Techstream)

(a) Check for DTCs.

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

SST : 09843-18040





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

(3) Observe the blinking pattern of the ABS warning and SLIP indicator lights and/or read the multi-information display (models with multi-information display) 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
* How to read DTCs:
* Diagnostic trouble codes are represented by the number of blinks of a warning light. For example, code 21 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) Check the details of the DTCs Vehicle Stability Control System (for BOSCH Made).

(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 DTCs.

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





SST : 09843-18040

(2) Turn the ignition 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 SST from the terminals of the DLC3.

HINT
Clearing the DTCs cannot be performed by disconnecting the battery terminal or the ECU-IG fuse.

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

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

(4) Check the details of the DTCs Vehicle Stability Control System (for BOSCH Made).

(b) Clear the DTCs.

(1) Connect the Techstream to the DLC3.

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

(3) Operate the Techstream to clear the codes.
