Built my Def Sensor Simulator

[KR1973]

This software is not a virus. It is an executable, and modern browsers will scare you into not running it.

If you take it from the website: DEF Sensor Simulator – Quick Build – DEF Sensor Simulator then you are safe.

Thanks Now I have the confidence!

That is the correct test. You do this with the chassis power off.

From this page:

DEF Sensor Simulator – Quick Build – DEF Sensor Simulator

Connecting to your motorhome CAN network:​

1. Make sure that before you unplug your def head that the ignition is turned off, then unplug your def head. You may need to cut a zip tie to provide working slack in the wiring.
   
2. Plug the simulator into the connection to your chassis wiring where the def head was plugged in.
3. Turn on your ignition, some or all of the fault codes should go away and the Check Engine and MIL (Malfunction Indicator Lamp) lights should extinguish within a few minutes.
4. If some codes remain, to clear your codes you will need to turn your ignition on (let all systems come up, about 20 seconds), then start your engine and fast idle for 5-6 minutes, shut down for 90 seconds, turn ignition on (wait for systems to boot 20 sec) start engine and fast idle for 5 min. You will do this a total of 3 times on the 4 cycle the codes should clear to the inactive status.
   Note: on older engines or engines with older ECM software, some codes may not completely clear on their own. In this case code clearing intervention may be required. This is something that is still under study, see the Troubleshooting section for more info.

Are you planning on testing once you get your coach? I want you to lead the way

Yes. I will be plugging it in as soon as possible.

Well I finished mine up, got brave and tested. Worked as advertised and no fault codes. I am going to carry in my spare parts bin and hope I never need it

@NWIP ... did you order the parts very recently. Need to get my stuff ordered tonight. Just wondering if there is a backlog.

I ordered about 4 weeks ago and everything was readily available, took about a week to receive all the parts.

if you’re comfortable doing a little bit of soldering, you may want to build the newer CANBed version.

Well like they say ... if you snooze you lose. Looks like the boards and CAN BUS items are now out of stock till mid-March. I will try again then. I did order the other parts that I could find.

@FLSteve - I just ordered canbus kit this morning. Plenty of stock--404 right now.

you only need one of these. It will need to be soldered, but that is very simple as it is just 4 connectors that need to be used.

@redbaron ... Where are the instructions (link) for using this one?

@redbaron ... just one question. When you click on the link in the instructions it takes you to this one that appears to have all the parts that need to be soldered on. The above link does not show them. Any issue getting the one in the link since it matches the instructions?

Amazing what you have to do to keep your $500,000+ RV running...

Yep ... and I just spend another $71 on the parts to build my DEF Sensor Simulator. Just got it finished and programed. Hope it's never needed, but I will put it in the category with life insurance, extended service policies, etc. etc.
