New battery... won’t start. key reset? engine immobilization? (1 Viewer)

[bloc]

Put meter in DC mode and red lead to + black to -. Should read at least 12.5 or so.

Starter failure on 200s will usually be accompanied by a click as the solenoid activates. The failure is almost always the solenoid contacts not bridging current.. even if they do try to activate.

OP is there a click from the passenger side of the engine right as you hit the start button?

It seems as though your immobilizer needs to be reset. Not sure how to do that in a 200. Maybe try pushing the unlock button on the FOB several times? It's probably in the owners manual.

put the dial on DC voltage as shown, hold the red probe to + battery terminal, black probe to - battery terminal.

What were the circumstances of the dead battery you replaced? Were you having starting problems?

The battery can have enough power or just good enough connections to light the lights, but not enough oomph or good enough connections to activate the starter solenoid. Jump starting attempt and/or cleaning terminals are good ideas and easy to do first

 

[sdnative]

That is a little low but should be more than enough to start the vehicle. It's probably a matter of just resetting the immobilizer.

On a related topic, did you specifically ask for AGM? The factory charging system is not ideal for charging AGM batteries. Most people that use AGM batteries understand the tradeoffs using AGM vs flooded lead acid.

Everything was dead with old battery

May have jumped gun on new battery
But stuck in quarantine and we really
Need to get this thing started

the immobilizer part of the manual is not helpful at all

Your car needs to be in Park. See if you can cycle down to drive then back up to Park, I believe thats what you display was saying put it in park it won't start in gear.

It’s what the guy at autozone reccomended.
I can swap it out for a lead battery tomorrow. Now that I’m an expert at connecting the battery lol.

thanks but it is in park. I try to go to drive and reset.

Btw the old battery has 11.4 charge was it even dead

 

[RET2]

i believe it did this when we first hooked it up. Does it make sense to take the time to unhook and hook up again? Kind of a PItA.

You only have to remove 1 of the terminals to effectively disconnect the battery.

if it doesn’t think it’s in park you need to change it’s mind.
Double push start button. Then push brake and shift up and down. The push start again to turn off and then start as normal

Does the start button change color when you apply break and push button?

Foot on break makes it green.
press button stays green
Foot off break (lights are on) is orange

Thanks - it’s 2015 same manual but I’m not sure what that is telling me to do

Try closing all doors and hood and locking the doors with the FOB. Wait a minute or two. Then unlock with the FOB (press unlock a few times for good measure). Try to start the vehicle.

Does this have an aftermarket alarm / immobilizer?
