1. ABS diagnosis connector is located under side of master vacuum in engine compartment.
2. Key switch IG ON.





3. Connect the ABS diagnosis terminal (H) to the ground more than a second and continuously connect the terminals to retrieve all the fault codes.





4. The following procedure is how to check the digital code of "12" as an example.
- When the jumper wire is grounded ABS warning lamp is off. It indicates self-diagnosis function is started to operate.
- ABS warning lamp is off for 3.2 seconds and then it is ON & OFF rapidly (0.4 second) one time. It indicates first digit of code is "1".
- 1.2 seconds after first digit of code flashes, the ABS warning lamp is ON & OFF two times. It indicates second digit of code is "2".
- Above procedure is repeated three times. And then next code is followed by the same pattern.
- ^The code can be checked from the malfunction code list.
- ^Fault code "12" is just a start code which flashes out though there is no fault.





5. To clear diagnostic codes using brake pedal, it is the best to apply the brake pedal more than 6 times and to keep applying the brake pedal as fast as possible for more than 3 seconds.
Diagnostic codes can be cleared using the brake pedal when the ABS control module is in self-diagnosis function. If the brake pedal is depressed six times in three seconds while in code flash out mode, codes are cleared.

NOTICE:
a) Code flashout is not possible with a shorted ABS indicator light or diagnostic wire shorted high.
b) Clearing codes is not possible with an inoperative brake switch (code 18 exists).
