I recently did a charger conversion, and I am getting this code. I believe zzp sent me a bad pcm, but they do not have any info on this code QDM 1670. I also have code 0170 system to lean, which I believe is caused by the QDM code. Any help would be great!

 

QDM Deals with the PCM, it stands for Quad Driver Modules, and is commonly associated with PCM faults. I don't understand why ZZP wouldn't know what they are?

However, check your fuses, you may actually have a blown one for your AC unit, or similar. Remember to check both sides of your dash for the fuses.

Then disconnect your battery for an hour to clear the codes.

 

Could this pcm fault lead to a code 0170 system to lean? I have been searching and found that it is connected to the injector module.

 

P0170 could have many faults, injectors clogged, fuel filter, o2 sensor, etc.
