Should you try? How to erase a permanent code from your ECM/ECU

Discover if you can eliminate a PDTC using this technique. Permanent Diagnostic Trouble Codes (PDTCs) closely resemble standard Diagnostic Trouble Codes (DTCs). However, unlike their counterparts, PDTCs cannot be reset by disconnecting the vehicle's battery or cleared using an onboard diagnostic (OBD) scan tool or at least it's what we've been told.

Mode $0A lists emission-related "permanent" diagnostic trouble codes stored. As per CARB, any diagnostic trouble codes that is commanding MIL on and stored into non-volatile memory shall be logged as a permanent fault code.

This may have worked if the ignition switch was left in the on positiion and the lights left on to drain any residual power from the system.

I’m Wondering if maybe your vehicle has an auxiliary battery like many modern vehicles. Because if that’s the case, you would have to disconnect the aux battery as well otherwise the vehicle’s computer still has a power source. That’s just my guess of what may be the reason it didn’t work.

[mustangecoboosthpp]

You know you have to actually correct the issue that is causing the permanent code or it will just keep showing up. If all you are doing is trying to delete a permanent without correcting the issue the code will come back. The resister and alligator leads will clear a permanent code, some manufactures may have implemented the ability to store the code on a memory chip and not just in memory in which case you will have to use a computer to erase the permanent code.

Doing mine now. Less than $15 for clips and 10 resistors on Amazon. 👍

It's actually 2009 and newer vehicles with permanent codes and it's a federal law nationwide.

Is there a device that can easily delete driver monitoring cameras, lane keeping assist and all the rest of the crap?

[shaneburke]

im having same problem i just gound that granc caravan 11¹ to 15 have problems clearing permanent codes they are on bars lust of pri lrm cleating permanent codes section e i think the dealership has to clearvyhem if i read it right good luck if you find a solution hit me up

Ohm's law says that electricity follows the path of least resistance. When you install the yellow wire between terminals the resistor does nothing. 😂

[Nemesis-ynwv]

You don’t need a resistor. You can disconnect the terminals, wait five minutes then touch them together for a minute to fully discharge the system. All learned values and keep alive memory will be lost.

[matthewthompson]

You wasting your time. You must remedy what ever the problem is and then drive the vehicle till the ECM recognizes that the problem has been resolved. It's the only way!!!
