Installed the ABS module that came back from the eBay service (rapid_electronics). For $79 it was excellent service. 24 hour turnaround!! Mailed on Monday received back Friday.

Nice to not have ABS and brake light glaring at you !

I may have a battery discharge problem maybe from malfunctioning door sensors or ignition lock cylinder (potentially), I’ll open a separate thread on this…

I know I'm 10 days late but... Do you have the console radio controls for the 2nd row passengers? There's a YouTube video where someone found this. Might be as good a place as any to start.

Yes there are some buttons back there. Power is the only thing that does anything (enables and disables radio). No response from any of the other buttons.... not sure what I am doing wrong.

up front where the rear controls are, switch that one knob to aux iirc. then the rear panel should be able to control the ac temp fan speed and direction.

Thanks, how about the rear audio/radio controls ? They seem inactive except the Power button.
ive read the owners manual to learn how all that works, but really never used it. ive got a dvd player as well, have had the truck for 6 years and never even messed with it. manuals are free on line. mine was supposed to have two sets of head phones and a remote but i never got them things.

I am suggesting the radio controls can have a bad module and that is your parasitic loss. There's a YouTube video on it.

Oh I gotcha...

I think we figured out the parasitic loss. It happens when the vehicle is turned off, key removed, and dinging won't stop with the door open. What I end up doing is re-inserting the ignition key, moving the key to run position, bringing it to off again. It's almost like the ignition key coming out in the accessory mode..... doesn't happen very often. When this issue becomes often enough I'm sure I will need to address it. Guess its a worn ignition cylinder/switch ?
