DTC CHECK/CLEAR (When Using SST Check Wire)

1. 

   *a	Front view of DLC3

   Check the DTC.

   
   

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

      SST

      09843-18040

   2. Turn the engine switch on (IG).

   3. Observe the blinking pattern of the ABS warning, slip indicator and brake hold standby indicator lights in order to identify the DTC.

      Tech Tips

      If no code appears, inspect the TC and CG terminal circuit, and ABS warning, slip indicator and brake hold standby indicator light circuits.

      Trouble Area	See procedure
      TC and CG terminal circuit	Click here
      ABS warning light circuit (Remains on)	Click here
      ABS warning light circuit (Does not come on)	Click here
      Slip indicator light circuit (Remains on)	Click here
      Slip indicator light circuit (Does not come on)	Click here
      Brake hold standby indicator light circuit	Click here

   4. Count the number of blinks of the ABS warning, slip indicator and brake hold standby indicator lights.

      Tech Tips

      
      

      • 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 blinks, a 1.5 second pause, and then 1 blink).

      • 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.

      • If the brake hold operated indicator light is blinking before terminals of the DLC3 are connected, when terminals 13 (TC) and 4 (CG) of the DLC3 are connected, the brake hold operated indicator light stops blinking and turns off.

   5. Check the details of the DTCs.

   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.

      Tech Tips

      w/o Stop and Start System:

      The DTCs cannot be cleared by disconnecting the battery terminal or the ECU-IG1 NO. 6 fuse.

END OF DTC CHECK/CLEAR
