i have 2000 tl i got an auto start a660 model i think two way alarm/starter combo. the issue is sometimes when i start it using the remote the tcs light comes on and i cant turn it on or off. sometimes the tcs and abs light come on. also if i shut it off then use the key no lights. some daytime running lights dont come on. wonder if its install error or bad choice on bypass kit, apperently there two kinda one with a spare key one without. i have one without your key. or maybe defective unit? sometimes the unti works perfect! others its crazy.
