Do you guys have any problems with the ABS and brake light coming on right after you hit the start button on you timer? I do, and i set a code 0500 no vehicle speed sensor signal. I talked to Howard and he said hasn't heard of that problem. Well i did a little digging around in the shop manual and decided to put a jumper wire on fuse #3 (ABS and AWAL) So i have a jumper wire on #9 (engine) to #3 (ABS) so when the timer is on i have power to the ABS also. No lights and no codes works great. Let me now if it works for you too.. here is a pic take a look...
