Delete Auto Stop/Start ASAP!

[Jason B]

Probably should have watched the video, may do so today. But did do a fair amount of searching and didn't see much of anything attributing engine failures to use of ass, there were many many discussions and also some fleet mgrs chiming in saying they've seen lots of vehicles using it with 200k miles and no crank failures. Some automotive gurus even contend that engines have become more durable and longer lasting as a result of the changes associated with ass use. I did see what Mazda does for restarts - doing a gdi pulse into a cylinder that is ready and thus oft times does even use the starter. And once again the overwhelming majority of automotive experts contend that restarting a warm engine results in minimal wear. So yeah a single youtube video vs decades of actual use with seemingly limited reports of ass causing premature engine failures . But like the GM 6.2l example with the chorus of "I knew it, 0w-20 destroys engines" is similar to some of the stuff on the web where people still want to belief ass is shortening their engine life, to them I say "duh hit the off button and sleep well at night " or on here unplug that black connector at the batt.

Yeah, I'm not worried about engine wear. Bearings will still have a good coating of oil after being shut off for 30 - 60 seconds.

Research is always good! As are open discussions. We all learn from both.

I think the main point is that I have no trouble controlling auto start stop with brake pressure. So it's not like I am needlessly using it for short stops.

If you did not have auto start stop and you got stuck in a traffic jam for an extended period of time you would shut down the motor anyway.

Only if the weather was nice.

I've always been leery of the ASS. I had some warranty work done a few years ago due to an electronic issue. When I got my truck back, the ASS quit working - I was really happy. Prior, I would manipulate it with my brake pedal. It can't be good for the starter either.

Dunedain - Your battery is slowly going, that is why ASS no longer works. They have a battery voltage monitor and if it thinks the battery is getting low it will disable ASS.
Try charging you battery with a charger and then perform the BMS reset procedure:

To perform a Ford Ranger BMS reset, turn the ignition to the "on" position without starting the engine, flash the high beams five times, press and release the brake pedal three times, and wait for the battery light to flash to confirm the reset. Ensure the vehicle's doors are closed before starting, and complete the sequence of high beam and brake pedal presses within a 10-second window.

If above does not get ASS working again then your battery is on the way down. But, being AGM, it will continue to operate the vehicle in all other aspects for another two years or so.

Ask me how I know all this...
