Remote start not working?

[Minty JL]

Not like you really needed it.

(and back to batteries - it's likely to be worse in extreme temperatures)

The remote start not working on the JL was the first indicator. Did the normal voltage checked, then did a load test would drop from 12.4v to 7.9v in a matter of seconds.

Replaced the battery and good to go.

General rule of thumb, look at replacing the batteries every 36-48 months

My batteries are about 1 year old.
The remote start was not working in warm weather.
When I have the doors unlocked and double click the remote start button the exterior lights flash but the doors do not lock.

Have the doors been off?

No


Offroad dash display shows battery @ 12.1 V with the engine off. (When I am driving it usually runs @ 14.2V)

This makes me think the battery may be the culprit (even though it is less than 2 yrs old)

Hooked up the OBJScan (I've only used it once to set tire diameters) it has the following codes:

Reported by Heat Ventilation and A/C:
