Problem

I have had my Scanmaster hooked up for a short while and did so using Fred's page (Thanks Fred for the excellent write-up ). I was in the car this afternoon reading over the info from his site I printed out and was accounting for all of the sensors the Scanmaster was monitoring and checking them off of the packet as I came to them. After I had most of them checked off (I was interupted as I was picking the lady friend up) and I came to 4 which I didn't find on Fred's site.
1.A.E.S
2.C.L.E.
3.E.P.S.
4.E.P.D.

When displaying the other sensor readings and names, all of the letters seem to be functioning properly.

Can someone shed some light on this?

 

Bump.

 

Are you certain you're reading those correctly? Do you suppose a few of the LED's are messed up on the display?


First, I'd make certain you're reading the 'mode acronyms' correctly. My guess is that you've mixed a few up, because they are difficult to read. As far as I can tell, the closest sensor acronyms to what you listed are 1) ATS, 2) CEL, 3) TPS, and 4) TPP. Or something similar.


Do you still have the cruddy excuse for a "manual" that comes with the unit? You might run thru all of the sensor displays and match them to the 'display mode sheet'. It should be in this exact order:

[default display -- 02mV and knock/spark retard]
MAF - mass airflow
SP - spark advance
LP - left injector pulsewidth
rP - right injector pulsewidth
dtc - diagnostic trouble codes
MPH - miles/hr
LbL - left block learns (long term fuel trim)
rbL - right block learns (long term fuel trim)
CEL - fuel map cell #
Lin - left integrators (short term fuel trim)
rin - right integrators (short term fuel trim)
02L - left oxygen sensor
02r - right oxygen sensor
AtS - air temperature sensor (same as IAT)
CLt - coolant temperature sensor
tPS - throttle position sensor voltage
tPP - throttle position sensor percent
r - engine speed (rpm)
IAC - Idle air controller
bAt - battery voltage
Egr - Exhaust gas recirculation duty cycle
MAP - manifold absolute pressure sensor
bAr - barometric pressure (map reading before startup)
ACP - A/C pressure sensor
CPP - Carbon canister duty cycle (EVAP)



Other than that, I dont know what to tell you. I'll let someone else step in...

 

Here's a link to the original manual, if you were at all concerned that you had lost it: http://www.ramchargers.com/RamNews/T...LT1_manual.htm

 

Thanks for the reply.
I thought that might have been a possibility but all of the other sensors seem to be reading correctly.

I do have the original manual somewhere, I'll dig around at home and see if I can find it. In the meantime, I'll print the list you made for me and check them off as I go. Thanks again.

 

Mine has similar display quirks.
AES = ATS
CLE = CLT
EPS = TPS
EPD = TPD

All of your "E's are really T's. Don't ask why.
Are you sure that your Battery "BAt isn't reading BAE also?

 

Hmmm... bad batch of Scanmasters?

It sounds like the upper bar of the lower-case 't' is being lit up when it should not. This might be worth reporting to Ramchargers. For $250, I think you should be able to differentiate between E's and T's...


My car is currently torn apart, but I'm 99.9% certain that mine does not read that way. Granted, I've only owned one for a short while...

 

Are you sure you aren't just confusing the lower case "t" that the SM displays with an "e"? It would explain all your "oddities".

What values are displayed for each of the letter combos you posted...... do they match (AeS = AtS) the corresponding values listed in my ScanMaster writeup?

 

Mine do, for sure. I keep an eye on my "CLE" while driving. It usually is in the 175-190 range....definitely the coolant temp.

The M in mine displays as a single hump 'n" as well. For example, nAF and nAP are displayed for MAP and MAF. My Scanmaster has been in the car since Mike Licht (of Ramchargers) built the car in 1999.

 

Thanks for the help everyone. As a few suggested, the "e's" were supposed to be "t's".
