I just finished having my alarm installed w/ remote start...(manual 98 preludeSH) and as soon as everything was done the check engine light and atts light came on... Now i've read that the atts light automatically comes on when the check engine light comes on but can someone help figure out why check engine light came on? Im thinking its because the viper 550 remote start has to be tapped into your rpm sensor for the over and under rev protection safety feature. What should i do? Has anyone else had this problem after installing a remote start?

 

What code is the CEL throwing?

 

i have been able to reset the ECU and have the check engine light go away by disconnecting the battery for only a couple seconds. 3-5 secs max.

if you unhook it for longer, then your radio locks, and you lose the presets. if you unhook for 5 secs or less, the ECU resets, the error code goes away, and the radio is unaffected...

works for me. I've had my engine light and ATTS light come on a lot lately. I don't know why. it does it when it's really cold outside. I think it may have somethi8gn to do with my battery being on it's last legs.....
