WHAT DO ALL THE NUMBERS MEAN

Hey everybody, I just got done with the High-Idle mod and thanks again it works great. I had also flipped my odometer/ trip odom (holding trip/odom stick in for 4 seconds.) Anyhoot my question is when it goes in to "test" mode and gives real time data, ah does anybody here know what all those numbers, words(?) mean. They have to have a value and I'd like it to be to me also! I was just using the tachometer to verify the high idle mod. It all looks similar to what's on a scan gauge? I'm sure somewhere in these pages contains all the acronyms/ value for "using trip odom/ odom to scan......" right? I'll keep looking, thanks in advance.

 

Think they are counting out the trouble codes. Did you look in the manual for the truck.. I'm not near mine or I would look for you. Count the flashes, pause is the next number.

 

K I'll look at 'em a bit closer. But thanks, I know I'm off subject but do you like your MBRP pipe?

 

It's your thread... yes I like the pipe. Just something about the sound when you stand on it, raspy would be a good word.

 

heres the explanations of what each pid is showing.


GAGE - Carries out gauge sweep of all gauges, then displays the present gauge values. Also carries out the check sum test on ROM and EEPROM.

All segments illuminated.
Illuminates all odometer segments.

bulb
Illuminates all micro-controlled lamps and LEDs.

r ####
Returns to normal operation of all micro-controlled lamps and LEDs and displays hexadecimal value for ROM level (used when requesting assistance from the hotline).

nr####
Displays hexidecimal ROM level and type as stored in non-volatile memory (NVM).

EE ##
Displays hexadecimal value for EE level (used when requesting assistance from the hotline).

dt ####
Displays hexadecimal code for the final manufacturing date.

###C
Gas engines display last temperature gauge input value from SCP, temperature gauge will indicate present temperature. Diesel engine displays present temperature analog/digital input in decimal as a ratio, temperature gauge will indicate present temperature.

dtc ####
Displays a 16 bit DTC in hexidecimal format. DTCs displayed are those detected in continuous operation not during self-test.

EnG
Displays English speed value being input, speedometer will indicate present speed.

m
Displays metric speed value being input, speedometer will indicate present speed.
tAc Displays the tachometer value being input to the instrument cluster. Tachometer will indicate present rpm.

FUEL
Displays the present analog/digital fuel level being input to the instrument cluster as a ratio.

OIL
Displays the last analog/digital reading of the oil pressure switch contact resistance, oil gauge will indicate present level.

br
Displays the brake fluid level in an analog/digital ratio value.

bAt ##.#
Displays present battery analog/digital voltage.

rhEo
Displays present hexadecimal pulse width modulation (PWM) dimming input.

rhi, rhS, rho
Alternating 1 second display of pulse width modulation (PWM) input duty cycle, SCP hexidecimal dimming step, output driver counts in hexadecimal.

Cr
RUN/START sense circuit check.

PA, Pb, PC, and Pd
Displays 8-bit hexadecimal value for the Port A, B, C, and D readings (used when requesting information from the hotline).

PE0-PE7
Displays 8-bit hexadecimal value for the Port E0-Port E7 in analog/digital readings

 

Is what you seeing look like this?
196f
d2c7

Numbers that look something like that
could be Hexadecimal or Base-16

In mathematics and computing, hexadecimal (also base 16, or hex) is a positional
numeral system with a radix, or base, of 16. It uses sixteen distinct symbols,
most often the symbols 0–9 to represent values zero to nine, and A, B, C, D, E, F
(or alternatively a–f) to represent values ten to fifteen.


If that is the case it fairly easy to read if you have the key set
so that you can tell what each set means. You will find a lot of
the computer coding in the truck is done in Hex. it is usually easier
to have an interpreter to catch the data and convert it.

What actually is the point in showing this info to the average user.
Assumeing he can figure out what it means there is nothing he can really do with it.

It is like trying to code a program without actually knowing code and just looking in a book. You look up a code bit,type it in and then go look up the next one. Would take forever to compile your code.

This is why I am not a programer, never could memorize code.

 

Most of the test-mode readings ARE available via ODBII.

However, the lamp test IS pretty useful - especially when looking at a potential 6L purchase, it also WOWs the sales guy, and he might divulge something else they know about since he's likely to figure you'll find it yourself (especially if you have the SG2 connected)

This is such a great web site.

 

Thanks Mike I had to know. Now I do, oh my gosh my head is going to explode! Useful info when you need it. I knew I'd find the answer here, this place rocks. I'm still in the build up stage so go easy on me huh, I'm reading, doing, learning, doing, and repeat. That's what makes this place such a great asset.
I do agree Sean, it seems "easier to have an interpreter" convert the data.
I guess that would answer the need for a quality monitor, to catch and tell.?
I agree also Danny, I too could "never be a programer." I can get through most computer stuff, but code memorization? Na, I'm out.
On to the next project, after I learn what U0155 is? I really gotta make time for this truck. Thanks all for the feedback, this is such a place.

Ahhh the CAN network a whole nuther can of worms. LOL

 

The fun part is I can read "some" raw output but not all.
It does make ones head spin just like Linda Blair did.
The only thing is you don't get the green pea stuff spewing
out most times after you have looked at it a few times.

C programming language and also Perl are the only two
I would even atemp to try to read and both are so very
old at this point.

Yaiko Have you ever tried reading binary[machine language]
I used to know of a guy who wrote his programs only in binary. Humongous things LOL

 

I was started on self learning stuff. Just way to may 10101010 for me.

And YES I used a converter for that one.

I see a blond in a red dress.

 

LOL oh my god!!!!! I need to go dig up my old text book. There was a good example.
Basically "My name is JOHN" something like 4 paragraphs of binary to say that simple sentance. Something like that anyway.
Sorry 3 1/2 lines to say that must have been more to the statement of the example. Short lines
