On my pickup when I push the throttle to around 3,000 RPM's, mainly on hills, the e-brake light and abs light will come on. However the lights will turn off when I turn the engine off and back on again. I also just replaced the batteries in the truck because I found the OEM batteries were running at 330 cold cranks. unfortunately the problem still persists. I've had the brake sensors checked and they were fine. The dealer does not know what the problem could be. The dianostic does not show any record of the lights turning on.
