It was dead. The battery had been replaced one week ago.
I don't know. What is a parasitic draw?
Its a test that has to be done to find out exactly what is causing the battery to drain overnight.Heres is the test and is what needs to be done to finally fix this issue and should have been done to begin with it would have saved you alot of money.This is what you need them to do.ClickHereThese are the next steps.Hoped this helped.Positive feedback and bonuses greatly appreciated.Please rate excellent service so I get credit for my help anything lower leaves me negative feedback thanks.
So you think all the problems are related to the air flow sensors. This info is published by Toyota. Are Cadillac engines the same as Toyota? What does ECM stand for? Which type of MAF sensors does my caddy have? You're saying that because the MAF sensors don't work, the battery is dead? When the diagnostic device is placed on the engine, why doesn't it say that the MAF sensors are not OK? So the MAF sensors are drawing power from the battery? What else might be wrong with the car? I've had about four or five parts replaced in the engine. Are they all caused by this problem?
Sorry that was for another customer .This is what needs to be done to find the problem.Most common is a sticking relay or door lock actuator but this will pinpoint the issue.ClickHereHoped this helped.Positive feedback and bonuses greatly appreciated.Please rate excellent service so I get credit for my help anything lower leaves me negative feedback thanks.
I'm very confused. Now you say the info about the oxygen sensors was for another customer, not me. My problem is related to a sticking relay or door lock actuator. Please explain a sticking relay and door lock actuator. How do they relate to a dead battery? Thanks.
When I started the car yesterday afternoon it was OK. I did a few errands around town which took about one hour. It started fine each time I returned. The last time the ignition was turned off was about one hour. When I tried starting the vehicle, it was dead. Does this fit in with your idea of a shorted relay or door lock actuator fan? You posted infor about air flow sensors to me. Is that the parasitic draw test? Please confirm. Thanks.
yes those would cause the issues .The mass air flow sensor disregard.You need 9o have the parasitic draw test done to have this diagnosed correct.Heres the link again.ClickHereHoped this helped.Positive feedback and bonuses greatly appreciated.Please rate excellent service so I get credit for my help anything lower leaves me negative feedback thanks.
Thanks for all your help. I can't imagine what might be drawing power from my battery, but I will mention this to my mechanic. He has probably done this, but maybe not.
