Odd Electronic Behavior (Proximity Sensors and Door Locks)

Generally when you take in a battery to be tested, they:

  • usually charge it (you only gives a full good result starting as charged as it can get)
  • use a tester that tests and prints out:
    • SoH (State of Health) (??generally CCA compared to rated CCA??)
    • CCA (how many amps it can provide for 30 seconds at 0 degrees without dipping below 7v)
    • Rated CCA (how many CCA is should be brand new)
    • SoC (State of Charge) (current voltage vs rated voltage percentage, can be low if not charged, but only real handy if charged fully before test)
    • Internal Resistance (can show an internal issue, like a dead or shorted cell)
    • voltage (not as handy as other numbers)

Often times shortcuts are taken, or the test isn't good enough to show the actual issue. Most places will give you the results (instead of just saying "it good"). They are more likely to do a full correct test if you are attempting to warranty the battery at the place it was bought from.

 

SOC: 92%

Type:  AGM

Voltage:  12.70

Rated:  760 CCA

Measured:  625 CCA

Temperature:  68º F

Your battery is in okay shape. Nothing about any of those numbers indicate a current issue, or point to its demise anytime soon. I don't think any of your current issues are caused by the battery.

 

I ran my 2017 Escape down to 225 CCA for 6+ months, but it was annoying, and not worth it.

@DNBush: From the 2020 Edge Workshop Manual...

 

Placing your device cursor over underlined acronyms may yield popup full-words descriptions of the acronyms.

 

Switch Inhibit Feature

The switch inhibit feature prevents unauthorized access to the vehicle from the door lock control switches or the liftgate release switch. The BCM disables the function of both door lock control switches and the interior liftgate release switch 20 seconds after the vehicle is electronically locked. If any of these switches are activated while they are inhibited, a chime sounds and a message is displayed in the message center to indicate the switches are inhibited. The BCM enables the function of these switches when the vehicle is electronically unlocked.

 

This feature can be configured on/off through the message center.

 

Passive Entry (if equipped)

NOTE: To perform an accurate diagnosis of a concern, make sure the vehicle has a fully charged 12V battery and is in good condition when performing any electrical pinpoint tests. When the vehicle’s 12-volt battery is below a set threshold, certain features can be limited or become inoperative and lead to misdiagnosis.

 

NOTE: Some models are not equipped with the passive entry feature, but are equipped with push button start.

 

The passive entry feature unlocks or locks the doors or opens the liftgate without having to use a mechanical key blade or the RKE transmitter feature.

 

When the BCM detects a lock or unlock sensor is touched on an exterior door handle, or the exterior liftgate release button is pressed, it activates the low frequency antenna in the corresponding exterior door handle or inside the luggage compartment area. The low frequency antenna sends out a signal to activate the passive key. The passive key then responds by sending a high frequency signal back to the RTM . The RTM interprets the high frequency signal from the passive key and sends the information to the BCM . If the BCM detects a valid programmed passive key, the BCM unlocks the driver door, unlocks or locks all 4 doors, releases the liftgate latch (manual liftgate) or sends a command to the RGTM to power open the liftgate (power liftgate).

 

The passive entry (Intelligent Access) feature is part of vehicle load shed strategy.

 

Door Passive Entry

With a programmed passive key within 1 m (3.28 ft) outside a door, touch the lock or unlock sensor on the exterior door handle. The doors lock or unlock depending upon which sensor was touched on the handle. The unlock button is located on the inside of the handle and the lock button is located on the outside top face of the handle.

 

The driver front door passive entry feature either unlocks the driver door (if 2-stage unlock is enabled) or all four doors (if 2-stage unlock is disabled). The passive entry feature always locks all four doors when the lock button is touched.

 

The remaining doors passive entry feature always locks or unlocks all four doors.

 

Some vehicles with the SE option may not be equipped with the rear doors passive entry feature.

 

 

Because the door handle touch symptom is intermittent -- if you have not already -- you may want to try putting a new battery in your Intelligent Access Key...

Good luck!

The battery in the remote was replace, maybe two months ago.  I'm going to review all the info you sent however.  Thank you!

AutoZone.  They didn't use the acronym CCA and I am not a car guy so I'm too stupid to know what CCA means.   But that's what you're implying any way so I hope I've satisfied you.


That’s not his point at all.  The point was the only way to properly test it is to compare Cold Cranking Amps with the new rating, so if you never heard of CCA then there was a good chance they didn’t test that.  It was not an insult.
