My truck recently got a check engine light and simultaneously popped the message "service shifter" on the dashboard. I took it in to the dealer the next morning. They hooked up their code reader and reported to me it was a generic communication code that was not active. They cleared the code and charged me 100$ and told me to come back if it happens again. The next day the same code came on. I then used my OBD reader(not ready to drop another 100$ just yet) to retrieve the code. It was U1467. I tried looking up this code but it does not appear to be in any of the online databases. I know the U indicates communication and the 1 means vendor specific but I have know idea what the remainder of the code indicates. Any help would be greatly appreciated and please let me know if I can provide any additional info.

Thanks, hopefully my issue is not as bad as the guy with the 200... So far I have only thrown the one code but it has now happened 3 times.

Hi Twitchell,

The code is for "Implausible Driver Shift Request Signal Received on CAN and D-PT CAN." Let me know if there's anything else I can help with, like getting your vehicle back to the dealership.

Thanks Kori, I am going to try clearing the code myself again and see if the issue continues to happen at which point I will go back to the dealer. It would have been nice if they had been able to interpret the code like you just did. Thanks again!

If you are under 100,000 miles I would expect them to reimburse you for reading the codes. I would think the shifter is part of the transmission which is covered under the 100,000 mile powertrain warranty.

I hadn't thought of that. I am going to have to do some reading on what the warranty does and does not cover. I definitely need to educate myself. Thanks.

So this issue continues to happen, usually lasts a couple days then the clears itself. I have noticed that it always happens when it is raining or moist outside. I assume the moisture is shorting out something. If anyone has any suggestions I am open to them. I plan on taking to the dealer again when i have some time and letting them know about the moisture variable.

Probably not a bad idea, this dealer was the most convenient to get to but there are plenty others around. I was thinking I would give them one more chance seeing as I have only taken it there once. It was just disappointing that all they did was hook up their scan tool and clear the code.

This looks like another place where you posted, glad that you are still trying to find an answer


U1467-00-IMPLAUSIBLE DRIVER SHIFT REQUEST SIGNAL RECEIVED ON CAN AND DPT CAN

Theory of Operation:

The purpose of the diagnostic is to check the validity of the selected driving position. The driving position is received from two different CAN BUS signals. If both signals are invalid because of any of the monitored CAN failures (time-out, checksum, alive counter, signal invalid) this fault is set to indicate that the driving position can not be determined.

When Monitored:

When the ignition switch is turned to the run position and calibrated amount of time has expired.

No CAN BUS DTCs and ready to transmit.

Battery voltage is above a calibrated threshold.

Set Condition:

The failure is detected by the Transmission Control module (TCM) if the CAN monitoring detects any failure on both driving position signals of the two CAN BUS signals.

Possible Causes:

SHIFTER

ELECTRONIC SHIFT MODULE (ESM)

TCM - INTERNAL ERROR

I am mechanically inclined but not a mechanic so this info is a little hard me to interpret but the "possible causes" part I understand. When I go back to the dealer I am going to bring this info along and try to get them to fix it instead of just clearing the code. I hope I don't have bring it back to them ten times to get a fix. Those parts are covered under warranty so I would hope they would just replace whatever needs to be fixed and be done with it.

Just a quick update. I have still not gone back to the dealer. The issue has only come up once in the past month. I have also found that using the automatic starter will not work when the issue is happening but the next time I start the vehicle it reset the CEL.

Well, I put off dealing with this issue and it has come back to bite me. The service shifter error came up sporadically and would always clear itself after a little driving. Then two days ago after picking up my son at daycare the truck refused to start and displayed a "Service4wd" error. Battery is totally charged and I dont get any clicking when trying to start it. I had used 4wd that morning without issue, or so I thought. I went back to the daycare the next morning and took a look at the errors codes using my portable OBD reader. After that I disconnected the Negative battery terminal for a couple minutes and then reconnected and tried starting it again. No luck. I had the truck towed to the same dealership I had used previously. I gave the service manager the rundown of what happened and handed over my keys. Hopefully I will hear back today or tomorrow. For anyone interested the new codes are U0140, P0206, P0622, and P0688. I am totally bummed right and have been cursing all the damn electronics on the truck. I will follow up with the dealerships response when I get it.

I had a electrical issue with my truck ended up being a bad ground. I figured it out myself after a few trips to the dealer . The dash cluster would go crazy , fog lights go on and off and radio shut off. And at one point it would lose electric power steering

Hello Twitchell
I might have good news for you. After four trips to the dealer (two by tow truck), and $1400 later, I think the problem is fixed.
A new starter motor was installed but it didn't fix the problem. Here's what the Dealer's last invoice said:
Cause: The Engine Ground had higher resistance than the Body Ground. The problem was traced to the Engine Ground Cable which had been improperly installed (cross-threaded?) and caused corrosion on the Cable Eyelet. (which may explain the damp weather factor).
Correction: Dealer repaired cable eyelet and installed new bolt in new location.

It was explained to me as a 'back current' to the Power Control Module.
Truck has started every time for 9 days.....

Let me know if you need copies of my invoices. I could scan & post them if necessary.
Good Luck.

Hey Dan, Funny story, they are replacing the starter motor today.... I will definitely talk to them about checking the engine ground cable. I will post an update tomorrow. If you think copies of the invoices would help I would appreciate you scanning them, but no big deal if it is a pain.

I picked up the truck yesterday. Everything appears to be working so far. They ended up replacing the starter and then when the codes were still occurring they cleaned off a "buildup" from the started ground connection. I made sure to confirm the order that it was done in. The service manager was very nice and offered to talk to the mechanic when I asked if the starter was actually needed. She is supposed to get back to me about it today. The total bill was $460. It was $95 to clean the ground connection and the rest went to parts\labor for the starter. I am thinking now that it would be a good idea to do the big three ground wires on the truck to make sure this doesn't happen again, I am just unsure if that would affect my warranty.

I wouldn't be worried, it is very unlikely the dealer will blame bigger gauge wires for any problem, much less notice that you have larger wiring
