Cummins Scan Tool?

[vito.a]

I have an Equus Nova OBD II scan tool for cars, but of course it will not work on the heavy duty Cummins applications, (or is there an adapter)?

Can I check codes with the Aladdin System?

I'm interested in what are you using for a Cummins Scan Tool?
Are you able to get everything you need with a ScanGauge D, or are you using a specific heavy duty diesel scan tool, or are you using a laptop electrical connector with software?
Can you also reset/clear codes with your tool?

Please include aprox cost and if I need a protocol interpreter?

Thanks

Have you tried torque?

I have a Silverleaf VMPCS system, I bought it from RV Upgrades, had the best price.

You can download the software from here for free.

VMSpc | SilverLeaf Electronics, Inc.

It does log any Cummins faults, the new version will actually give you an alarm if a fault happens.

Problem is that the Cummins codes are proprietary and are not readily available to the common person. Each manufacturer of "code readers" has its own set of Cummins codes that mean nothing to a Cummins dealer.

I had a fault code show up on the Silverleaf of 11 18 1. That meant nothing to the Cummins people but a call to Silverleaf gave me the correct code of 539. That means something to Cummins so they can now tell me what is wrong and what needs to be fixed.

Try looking here:https://cumminsengines.com/powerspec
It is software by Cummins (NOT Insite). You need an inline adaptor to use it but they are available from places like B-B Electronics.
I think its a very useful tool. Does a lot including reading fault codes.

the codes are governor by the SAE standard, and the protocol as defined by the standard.
J1708, J1939 and J1587, get a copy and read it.

The Cummins' engine troubleshooting guides list not only the Cummins proprietary codes, but the codes for other common protocols.



Here you can see that Cummins code 131 is SPN code 091. SPN or suspect part number, is used by J1939 for sure. You can find these codes very easily by doing an internet search.

Depends on how fancy you want to get. My guys have this to diagnose our fleet. About $4000 with annual subscription.

JPRO Professional Diagnostic Software & Adapter Kit - JPRO Fleet Products

Not exactly for the DIY'er. Cummins can come out and diagnose several times for $4000

I use Scan D and it takes leg eork to figure the code out. I went to Cummins and they did a scan, told me what the problem was and even gave me a print out. Cost? $0.00. I almost fell over. They are back logged and my appt is 4 Oct to get it fixed. Jake

Have the VMSpc. Cummins quickserve site will let you convert the SPN/FMI codes to Cummins codes. Also links to repair procedures.

Thanks for all the responses.


PandK, is the B&B adapter for serial port only?
I assume you need both the converter and the cable?

[PandK]

I believe it is serial only but will check.
Yes you need the cable also.
If your computer does nothave a serial port a USB to serial converter may work.

I use VmsPC also and Silverleaf makes a USB interface and sometimes has them on sale, used or traded in. VmsPC is excellent.

Looks like my original converter is serial only. One choice of USB to serial is here: http://www.bb-elec.com/Products/USB-...onverters.aspx

Yes, they haven't made computers with serial ports for over 15 years now and there are problems with USB to serial converters.
Thanks
