DTC CHECK / CLEAR

1. DTC CHECK / CLEAR (when Using Techstream)

(a) Check for DTCs.

(1) Connect the Techstream to the DLC3.

(2) Turn the ignition switch to ON.

(3) Turn the Techstream on.

(4) Enter the following menus: Chassis / ABS/VSC/TRAC / Trouble Codes.

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

(b) Clear the DTCs.

(1) Connect the Techstream to the DLC3.

(2) Turn the ignition switch to ON.

(3) Turn the Techstream on.

(4) Enter the following menus: Chassis / ABS/VSC/TRAC / Trouble Codes.

(5) Operate the Techstream to clear the codes.

HINT:

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

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

(3) Turn the ignition switch to ON.

(4) Read the DTCs output from the ABS warning light and slip indicator light in the combination meter.

HINT:

When the system is normal, the ABS warning light and slip indicator light blink at 0.25 seconds intervals (0.25 seconds on and 0.25 seconds off).
When only 1 DTC is stored, the light outputs the same code after an interval of 4 seconds. Example: When DTC 21 is stored, 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 stored, 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 the ABS warning light and slip indicator light circuits.

Trouble Area	See Procedure

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)

(5) The codes are explained in the code table.
