The ABS, SLIP and TRAC lights are always on. I went to autozone but no codes were found.Next I followed the procedure for reading ABS codes. I grounded pin 4 and 9 on my 2001 AE Maxima. Instead of the ABS light flashing the SLIP light flashed? It flashed 1 time slow, 2 times fast. Paused a couple seconds followed by 3 slow flashes and 5 fast flashes. Then this pattern repeats. Does this mean code 35 for right rear ABS sensor?

 

after replacing my front wheel bearings my ABS light came on... needless to say the pin grounding didn't do a thing for me neither... luckily for me I knew it was one of the front sensors so I just used a volt meter to check the resistance on both abs sensors and found out that the FD was out... just disconnect from the connector and test with the volt meter if I remember correctly it should be something between .850~1.85 ohms of resistance
