Scary Problem After Running Amp Cable Pls Help!!! Abs/dsc
 

PROBLEM!!!!!! pls help! i removed the washer bottle and drilled a hole not 2 far in to the car, saw i had 2 stick the wie downwards and managed 2 get it right and was happy and excited 2 finish the rest of the wiring but went 2 the shop 2 get a sof drink but was shocked when i was driving to the shop i saw when i pushed my BRAKE pedal the ABS light on the right side guage display came on and the light which shows a car with a slippery wheel mark sign below it on the middle guage display also came on simultaneously. The ABS is also not working! IM CONCERNED!! W.T.F? when i switch the 8 off and start it up again the lights r off but as soon as i touch the brake pedal the same thing happens!

take a good look around your brake lines and be sure you did not drill into it.check the ground where you were working and see if there is any fliud(brake)around.now the question is did you disconnect the battery when you started(should have).it is normal for the system to be recalibrated if you undo the battery .before you drive off turn your wheels all the way to the right..then all the way to the left.. then turn the wheels straight.on your brakes they should work as normal before the battery was taken loose.check all around the area you did your work in and be sure everything is fused not to harm the electrical system.hope this helps!

checked 4 brake fluid, tried the steering thing, nothing. did'nt disconnect the battery, should of as u said. do u know where any other fuses r located? besides the fuses by the side front panel, checked them and all were ok.

I think you may need to get under the dash and see what wires you may have drilled into. :(

And/or check along the path of the wiring you did to see if any connectors got pulled or damaged wires.

Where did you tap into power? Direct to batt?

got under the dash 2day and checked if i did drilled into any wires behind rubber matt and in front, nothing. checked fuses in engine bay, all ok. i did tap the 4 guage cable directly to the battery terminal with a in line fuse which is not yet connected 2 any thing. i also checked the plugs, looks fine appreciate ur help ??????

Sounds like the wheel speed sensor info from one of the wheels isn't available. I'd trace that wiring to see if a connector was pulled or a wire damaged.

if you disconnected the battery, you need to reset the steering. turn the key on, turn the wheel all the way left, then all the way right, then turn key off, you should be good

first u need to find out what code was set in the abs module. That would help alot. Alot of abs modules will not turn out the light until the code has been cleared. Try disconnecting you battery for 30 min to clear ecu memory. After you reconnect you will have to relearn the steering angle sensor (turn wheel all the way to the right then all the way to the left the at center. hopefully this helps.

thanx 4 da help so far. after trying all these things and stripping the harness behind the dash finding no damage or loose plugs i took the 8 to my dealer and got them 2 plug their pc in 2 c wassup. they seem 2 think the switch on the brake pump unit (Bosch) in the engine bay is faulty, and is a sealed unit so they haved 2 replace the whole unit under warranty, cost of Rands 25000.00/Dollars 2500.00. they say they will have the new unit on Mon or Tues. I asked if it was any thing i did to damage any thing after showing them everything i stripped and did, they said it was just coincidence... will keep u's posted.
