hey guys coming back from a little road trip and my abs light and my brake light came on my dash...it kept going on and off and beeping every damn time...neways just plugged in my superchips and 2 codes came up C1036 and C1030. any of you guys know these or have the link to all the codes since i just tried searching and cant find it anywhere. thanks

 

Did'nt find any info on C1030, check the wheel speed sensor on top of rear differential. It is usually the reason that you have these 2 lights on. Part number is 5032220AA. Should cost about $8.00
hope this helps.



C1036-REAR WHEEL SPEED SENSOR CIRCUIT (EBC125)





For a complete wiring diagram Refer to Section 8W[/b].
[ul][*]When Monitored:
With the ignition on and no system under voltage or over voltage condition present.[*]Set Condition:[/b]
If the measured wheel speed sensor feedback voltage is less than .277 volts, the sensor is considered open.
If the measured wheel speed sensor feedback voltage is greater than 1.277 volts, or if a sensor over current condition is detected, the sensor is considered shorted.
If a shorted or open condition is present for more than 100 msec, the DTC will set.[/ul]

same thing happened to me, fill up your brake fluid .. it'll go off

 

i forgot to say .. does it go on and off and ding numerous times in a row.. mostly when you go over a rough road surface .. i drove like that for 2 months and had no idea what it was and it drove me insane, finally a guy at the auto store told me to fill up my brake fluid .. sure enough it was that easy no dings since .. i'd try that beore checkin all those sensors and stuff
