Linde H18T 391 Series Check Engine Light

I have a linde H18T 391 Series with the check engine light on, it appears to have a fuel issue, acts like its starving for fuel. Rev it up and it will die on its way back down. Unit has a newer cobra vaporizer and the carb has been cleaned. I have seem to misplaced my cable 3003652504 for the impco econtrol side of a linde 391 Series, is there any other way to check what the fault is in pathfinder with out the cable. Currently when I connect to the LHC it shows a engine fault under I/O but that does not help diagnose the problem. Is there a way to manually jump a wire and read a code? Anyone has a good source for one of these cables?

*Update* Read Check Engine Light DTC 1151

Thank you Andrew!

So this cable connects directly to the laptop, right?

Without an interface

Thank you

part number L3003652504 for LPG , L3003652503 for Diesel

You need pathfinder software, the engine management software is in the "H" section of the drop down menu. Think the software you need for your truck is for impco system.

Thank you,

Is that cable available through TVH?

Which software is needed for accessing that gas system?

Or should i just remove the LEDs from the display? :D

Thank you

You need a diffenet cable to connect to the gas system and you will not be able to get the check engine light to clear until you clear the error codes. Linde no longer support pathfinder

Hello, I have a similar issue, only without any malfunctions.
I get the check engine light and the one left to it. These lights came on after an unsuccesful shut off. The shut off valve did not close properly. The next day it worked fine, no fuel issues. I took apart the fuel shut off valve cleaned it without any result. Also cleaned the MAP sensor. Even if I disconnect the battery it comes back on immediately.
There is no O2 sensor in this model. Also what do you mean by trim valve?
Any suggestions?
I also have Pathfinder but i can not find any program to connect to the ecu to read the codes.

Truck is a 392-02 2014

Thank you

We replaced the oxygen sensor with a bosch 15730 ~$50.00, and we still were having DTC Codes randomly, replaced the trim valve and it solved all of our problems.

We purchased the cables thru our local linde dealer. We are not a linde dealer but lucky enough to have a copy of pathfinder. You can purchase the cable thru TVH by calling your sales rep, We just couldn't wait the for 4 week lead time to diagnose the truck. If you require the cables and can wait they are significantly cheaper thru TVH.

Future notes for anyone else regarding connecting to a Linde Truck for engine/DTC/Emission purposes. Linde Says to use "E-Control" Software, We couldn't get it to connect to a Tier III Truck. To Connect to the truck we used Impco DST Tier III with the generic password only after we installed Impco 32 Bit Canbus software even though we were only utilizing the serial port.

Our check engine light was DTC 1151 - High LPG - We believe we have a defective Oxygen Sensor. Local dealer is ~4 days out on a replacement we are going to try a Universal Bosch 4 Wire Heated Unit in the morning

I know your deepest secret fear...

Only way to get the cable is through a Linde dealer, if you have pathfinder you must be a linde dealer? I ran the number on TVH with no luck, there is no other way to get the fault code that I'm aware of, if a regulator and carb don't work the next stop would be control valve, assuming you've checked the basics, spark, compression ect..
