Post Help with an equation for torque converter lock up status
on: August 22, 2019 (GMT)

Wondering if anyone could help me out with trying to get the Torque Converter lockup status working the way I would like? This is on a Ram 2500 but figured someone here might know how to manipulate the equation to get what I am looking for?

What I have now is the following (was started by mopar1973man)

PID: 22B09B
Long Name: TQ Conv Lock Stat
Short Name: TQ LCK
Minimum value: 0
Maximum value: 275
Scale Factor: 1x
Unit Type: Auto
Equation: A

Using this equation I get output values of the following 128, 64, and 32. 32 being when it locks up, 128 is unlocked, 64 is something in between that I am not sure about. I can view these changing if I just use a standard number widget.

What I would like to do is use a On/Off widget to just show when it locks up (says on and turns green when locked) Is there a equation that I could use that would trigger a simple on/off bit(I think that would be the correct thing?) when it reads a value of 32?

Thanks!

You might try…

Bit(A:5) or {A:5}

Lookup function would be useful for
showing LOCKED or UNLOCKED.

Thanks, I’ll give that a try. I don’t have much of a software background so I’m just trying to piece this together.

Any idea what a lookup string would look like to do what you are talking about?

Would it be something like this?

LOOKUP(A:5 :1=’Locked’:2=’Unlocked’)

Thanks again!

Bit examinations are 0 or 1.

Lookup with A would use 128, 64, 32 values.

Lookup(A::128=’UNLOCKED’:32=’LOCKED’)

Lookup(Bit(A:5)::0=’UNLOCKED’:1=’LOCKED’)

Thanks for the help Capp! All of those examples worked. The BIT examples toggle on/off and the lookup displayed, unlocked, locked etc.

I think I am going to stick with this one..

Lookup(A::128=’UNLOCKED’:32=’LOCKED’)

Since there was another value (64) that seemed to be in between the unlock and lock state I added that as “locking” so I can see the transition of the different states

Lookup(A::128=’UNLOCKED’:64=”LOCKING”:32=’LOCKED’)

As I drive I can monitor it going from Unlocked-Locking-Locked now.

One last question I can’t find an answer on. Is there also a way to take that equation I am using and have it trigger a green background on the widget (like the on/off widget) when it goes into lock state?

Thanks, you have been a huge help!

Not that I am aware.
