      4. Turn the Techstream on.
      5. Enter the following menus: Chassis / ABS/VSC/TRAC / DTC.
      6. Check the details of the DTCs. Refer to DIAGNOSTIC TROUBLE CODE CHART .

        HINT: 

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

    2. Clear the DTC.
      1. Turn the ignition switch off.
      2. Connect the Techstream to the DLC3.
      3. Turn the ignition switch to ON.

      2. Turn the ignition switch to ON.
      3. Observe the blinking pattern of the ABS warning light in order to identify the DTC.

        HINT: 

        • If no code appears, inspect the ABS warning light circuit or TC and CG terminal circuit.
        Trouble Areas See
        ABS warning light circuit (Remains on) Refer to ABS Warning Light Remains ON
        ABS warning light circuit (Does not come on) Refer to ABS Warning Light does not Come ON
        TC and CG terminal circuit Refer to TC and CG Terminal Circuit
      4. Count the number of blinks of the ABS warning light.

        HINT: 

        • When the system is operating correctly, each light will blink continuously in a pattern of 0.25 seconds on, then 0.25 seconds off.
        • When one DTC is output, each lamp will output the same code at 4 second intervals. (For example, Code 21 would be output as 2 flashes, a 1.5-second pause, and then 1 flash)
        • When 2 or more DTCs are output, each lamp 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 set, they are output in order starting with the lowest DTC number.
        • DTCs are explained in DTC chart. Refer to DIAGNOSTIC TROUBLE CODE CHART .
      5. After completing the check, disconnect SST from terminals TC and CG of the DLC3, and turn the ignition switch off.
    2. Clear DTCs.
      1. Using SST, connect terminals TC and CG of the DLC3.

      4. Check that the warning light blinks in the normal system indication pattern.
      5. Remove SST from the terminals of the DLC3.
      6. Turn the ignition switch off.

        HINT: 

        Clearing the DTCs cannot be performed by removing the battery cable.
