DTC CHECK / CLEAR

1. DTC CHECK/CLEAR (When Using Techstream)

(a) Check the DTC.

(1) Turn the ignition switch off.

(2) Connect the Techstream to the DLC3.

(3) Turn the ignition switch to ON.

(4) Turn the Techstream on.

(5) Read the DTCs following the prompts on the Techstream screen. Enter the following menus: Chassis / ABS/VSC/TRAC / Trouble Codes.

(6) Check the details of the DTCs (See page ). ).

(b) Clear the DTC.

(1) Turn the ignition switch off.

(2) Connect the Techstream to the DLC3.

(3) Turn the ignition switch to ON.

(4) Turn the Techstream on.

(5) Operate the Techstream to clear the codes. Enter the following menus: Chassis / ABS/VSC/TRAC / Trouble Codes.

(6) Clear the DTCs by following the prompts on the Techstream.

HINT:

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

2. DTC CHECK/CLEAR (When Using SST Check Wire)

(a) Check the DTC.

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

SST: 09843-18040

(2) Turn the ignition switch to ON.

(3) Observe the blinking pattern of the ABS warning and slip indicator lights in order to identify the DTC.

HINT:

If no code appears, inspect the TC and CG terminal circuit, and ABS warning and slip indicator lights circuits.

Trouble Area

See procedure

TC and CG terminal circuit

ABS warning light circuit (Remains on)

ABS warning light circuit (Does not come on)

Slip indicator light circuit (Remains on)

Slip indicator light circuit (Does not come on)

(4) Count the number of blinks of the ABS warning and slip indicator lights.

HINT:

  • 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.

(5) Check the details of the DTCs.
