sweeet!!!

gonna need it today for sure!! well, at least around here in CT... in the 90's and HUUUUMID as HELL today....

Update: Battery now goes dead after a couple of days with Trinity hooked up , so far while in logging mode and/or just left on main screen. Testing for other possibilities, will inform with results as available! never did this previous to the A/C repair. Maybe it will help with others having same symptoms (as to where the problem is located)

Grrr. Lew?

Ill Born, if you get a chance, after the car has been parked for a few hours with the Trinity plugged in, reach under the car and see if the O2 sensors are warm...

Will do over the weekend, she`s glowing cherry red at the moment!

Car sitting no Trinity - 02`s cold - .5 volt draw (main power lead to fuse box)
Car sitting with Trinity no key activation (2hr sitting ) - 02`s cold - .7 volt draw "
Car sitting with Trinity key activation (2hr sitting) - 02`s cold - .7 volt draw "
Car sitting with Trinity car run 5min. (2hr sitting) - 02`s cold - .7 volt draw "
Original backup installed, Trinity removed (2hr sitting) - 02`s cold - .5 volt draw "

With the number of times the batt died (fully charged and tested before this) the DIC is showing "CAL" and this maybe part of the .5volts as the car has to complete this in order to close/ complete the cal function, which starts from scratch everytime the batt is removed/dies. So next, as time permits is to get the car to complete this function on its own and then try again to see if it can be replicated.

don't "Lew" me... I dunno... I don't ever leave my trinity plugged in...

I only plug it in when I'm actually using it....

and no, I'm not testing this scenario either.. just put in a brand new battery last year for $150+ optima...


thanks for YOUR results Ill_Born!!!

Your welcome, Lew

I can tell you that the Trinity is not at fault! It does power down to a sleep mode as they(Diablo) say.

The car manufactures all design the ODB port the same ( standardized), this port is given certain parameters to expect from/to activity. Somehow Diablo has to modify/alter/change these expected numbers/data to refelect the new actual parameters while the Trinity/inTune is in the sleep state. Then the BCM can remain in its normal state, as if there is nothing attached.

Here is some info to back this up:

Circuit/System Description

A vehicles power mode master (PMM) is the body control module (BCM). The ignition switch is a low current switch with multiple discrete ignition switch signals to the PMM for determination of the power mode. The PMM receives the ignition switch signals, and additionally reference voltage signal from the BCM, through the ignition switch and back to the BCM. There are redundancies within the PMM system that can allow operation of certain subsystems when there are faults in the ignition switch circuits. Other information such as serial data input from other modules and DTC`s is also used to determine what power mode signals and information is transmitted by the PMM. The BCM logic uses all this information to identify the operators desired power mode and activate specific discrete signals and serial data messages for the operation of many different subsystems as necessary. Other modules which have switched voltage inputs may operate in a default mode if the PMM serial data message does not match what the individual module can see from its own connections.
The PMM will activate relays and other direct inputs/outputs of the PMM as needed according to the calculated power mode. Several relays controlled by the BCM are switched ignition voltage they are pass through circuits within the BCM directly from the ignition switch. If these circuits short to ground, the fuse to the ignition switch will open.
Some system functions may operate one time and not the next with a specific fault in the ignition switch circuits depending on the vehicle operating conditions when the fault/discrepancies occurred.
Some actions from such conditions:
- The vehicle may or may not start
- Instrument panel indicators may illuminate or not or illuminate at inappropriate times
- Remote start may operate incorrectly
- Ignition key may not return to off Specific Retained Accessory Power (RAP) functions may operate while others do not
