   Check for DTCs.

   
   

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

      SST

      09843-18040

   2. Turn the ignition switch to ON.

   3. Read the DTCs output from the ABS warning light and slip indicator light in the combination meter.

      Tech Tips

      
      

      • When the system is normal, the ABS warning light and slip indicator light blink at 0.25 second intervals (0.25 seconds on and 0.25 seconds off).

      • When only 1 DTC is output, the light outputs the same code after an interval of 4 seconds. Example: when DTC 21 is output, the light blinks twice, turns off for 1.5 seconds, blinks once, turns off for 4 seconds, and then repeats this output pattern.

      • When 2 or more DTCs are output, the 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 is output, inspect the TC and CG terminal circuit and ABS warning and slip indicator light circuits.
