did you use the LT3 tab and then engine ?

 

[brucevdm]

did you use the LT3 tab and then engine ?

I just clicked on the select control module then engine tab then fault codes?

 

[JMR]

try and use the LT3 tab first and then click engine ( LT stands for Light trucks) or address 91

I just googled it now, i dont see that tab at the tab though?

 

[JMR]

I j

when you open vcds , click select , then all the way to the right of the tabs you'll have one marked LT3 , click on that one and then engine ( address 91 ) or do a direct entry address , type 91 and go

I dont have that tab and if i type in at the bottom left adress 91 it fails

No tab and the adress 91 fails

hmm...maybe on that year model van VCDS does away with LT3 tab ? should look like this

yea i dont have that tab, but thank you, any other way to assist me?

 

[JMR]

not unless i can identify the error sir , it's an unknown error so far , but have a bit of patience ( maybe @Uwe @Dana @Jef will give us some input ? )

ok, is there not something im doing wrong with vcds thats not letting me show the lt3 tab? i have the latest version on laptop

That is only used/necessary for the LT3 generation of Crafter (Typ 2E/2F, 2006–2017), which was a mix of VAG and MBZ modules. The current one (Typ SY/SZ, 2018 on) is all VAG and is completely normal from a diagnostic standpoint.

-Uwe-

 

[JMR]

i don't think you're doing anything wrong , i haven't had a 2018 VW Crafter for a diagnosis yet but for sure the older years (2008-2014 0 would link up to the ecu through LT3 tab since they are using a different protocol or something ( never was sure about it either ). Maybe the VCDS doesn't have a ROD file for that vehicle yet ? Maybe the boss will help us both understand this problem

yeah , i thought so myself in an upper post ( #9). So , what seems to be the problem with this 2018 ecu ? Thanks

24838 - ROD - Unknown Error Code

I believe that fault should decode to:
P100600 -- Torque Difference Cylinder 3: Limit Value Exceeded

Check compression? Injectors?

-Uwe-

 

[JMR]

i could agree , if one injector is acting up it can create startability issues or power loss ..

 

[Uwe]

Maybe the boss will help us both understand this problem

I'd like to see a complete Auto-Scan for context. I can't tell if it had loaded a ROD file or not from that snippet.

all injectors values on vcds seems very similar to each other, there was one that was out of whack but replaced the one injector and coded it, now the values are similar but still the misfire

let me do a full scan report
