Using Flash Code Method

ABS trouble codes can be cleared using flash code method by grounding pin "H" of Data Link Connector (DLC) 3 times using following steps:

1) Turn ignition switch to RUN position. Ensure ANTI-LOCK light turns off after 3-4 seconds. If light remains on, a fault is still present and must be corrected. Place a jumper wire between pin "A" and pin "H" of DLC. When ANTI-LOCK light turns on, remove jumper wire from pin "H".

2) When light turns off, reconnect jumper wire to pin "H". ANTI-LOCK light will turn on again. Remove jumper wire from pin "H". Repeat previous step. When light turns off, reconnect jumper wire to pin "H". ANTI-LOCK light will turn on. Remove jumper wire to pin "H". ABS codes should now be cleared. Verify by checking codes. Code 12 should be displayed. If other codes are present, repeat code clearing process.
