problems turning off P154D and P154B

[n2brk]

I'm trying to help my buddy Denny get rid of these codes, and they just persist! I've tried turning them to X:not reported, No MIL - and I have tried selecting Non Emissions, MIL off.

Both times, the codes don't show up on "current DTC's" but they do show up when you search all modules for DTC's. Also, his Edge doesn't find them but his Snap-On does!!

Denny is going to the dealer for a remote start problem, and doesn't want any DTC's to pop, so I'm not 911 but am in a hurry to help him out.

Suggestions?!

Thanks!

I figure your working on a LMM since those codes don't exist in the LBZ.

the only thing i can suggest is that there are 2 "Non Emissions, MIL OFF" choices. try both...

E35's are really weird when it comes to DTC's trust me i know...

I believe ya!!!

Yes, LMM - sorry.

I didn't try both, thinking it was just a typo to have it listed twice. I'll give that a try and hope it works.

Thanks,

Codes will prevent remote start. Irony?

[n2brk]

no dice. Tried it all. Still stuck with P154D and no-worky on the key fob autostarter... fudge.

Trying to look up wiring schematic now to hopefully trick the sensor. Dunno what else to do!

well crazy enough, the codes are not preventing the key fob from starting the truck. The BCM was not configured properly from the stealership, and it starts just fine now... even with these codes that I can't clear. So, the long and short of it is that I can't get rid of the codes, but they weren't the root of the problem and appear to be benign. Oh well, at least the problem is solved.

Ever get these codes to disappear?

[n2brk]

no dice - but still working correctly and remote start still ok.

In the BOSCH ECM you can set it so that the codes will not show up under any condition except under an all modules DTC check. I've went through this with an LBZ and an LMM. Even though I tried everything, certain codes wil lstill show up when you do an all DTC check, but a regular OBD2 scan will not show them. I just chocked it up to a quirk in teh fact that we don't have access to the portion of the tuning that actually sets the code, but rather we just set it to ignore it per say.
