    This guide will let you read ABS fault codes, even if you do not have a scan tool available to assist you in diagnosing an ABS system fault.

    If there is a fault with your ABS system a warning light will illuminate on your instrument cluster. 20180805_122152.
    This can be caused by a number of things that may be wrong with the system. More often than not the fault is caused by a failing wheel speed sensor. It is not unknown for the ABS light to come on and then go off again, or come on until you turn off the car and remain off for several days before returning.

    There is a simply way of reading the codes that involves nothing more than the sacrifice of one paperclip to the car gods.

    unbend the paperclip so that it can be used as a tool
    20180805_122255.

    Locate your OBD2 port in the drivers side footwell, close to the kickpanel.
    20180805_122319. 20180805_122347.

    Using your newly made tool, insert the ends into pins 4 and 9
    20180805_122530.
    Then you will need to take your key, insert it into the ignition and turn the key to position II.

    Once this has been done, then the instrument cluster will light up as usual. However the ABS light after going through its test function, will begin to blink out any stored fault codes.



    When the light blinks, a long slow blink will represent 10 and a fast blink will represent a 1.

    As in the case of the video, the codes present are 15 and 61. From what I understand, code 61 can be ignored at this time as it represents low system voltage, because the system is only being powered by the battery at this time.

    The codes for the ABS system and what they represent.
    11 - wheel sensor (open/short to body ground/short to power) FR
    13 - wheel sensor (open/short to body ground/short to power) FL
    15 - wheel sensor (open/short to body ground/short to power) RR
    17 - wheel sensor (open/short to body ground/short to power) RL
    12 - wheel sensor (electrical noise/intermittent interruption) FR
    14 - wheel sensor (electrical noise/intermittent interruption) FL
    16 - wheel sensor (electrical noise/intermittent interruption) RR
    18 - wheel sensor (electrical noise/intermittent interruption) RL
    21 - pulse FR
    22 - pulse FL
    23 - pulse RR
    24 - pulse RL
    31 - solenoid (short to body ground/short to wire) FR-IN
    32 - solenoid (short to body ground/short to wire) FR-OUT
    33 - solenoid (short to body ground/short to wire) FL-IN
    34 - solenoid (short to body ground/short to wire) FL-OUT
    35 - solenoid (short to body ground/short to wire) RR-IN
    36 - solenoid (short to body ground/short to wire) RR-OUT
    37 - solenoid (short to body ground/short to wire) RL-IN
    38 - solenoid (short to body ground/short to wire) RL-OUT
    41 - wheel lock FR
    42 - wheel lock FL
    43 - wheel lock RR
    44 - wheel lock RL
    51 - motor lock
    52 - motor stuck OFF
    53 - motor stuck ON
    54 - fail-safe relay
    61 - ignition voltage
    62 - ignition voltage
    71 - different diameter tire
    81 - central processing unit (CPU)
