(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 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 light 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 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 set, they are output in order starting with the lowest DTC number.
* If no code is output, inspect the TC and CG terminal circuit and the ABS warning light and slip indicator light circuits.





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

ABS DTC









VSC DTC





* *: This DTC is output when the VSC system detects a malfunction in the ABS.

(6) Disconnect terminals 13 (TC) and 4 (CG) of the DLC3.

If 2 or more DTCs are output at the same time, the DTCs are output in ascending order.
