More DTCs! Car is Dead.

Today the Magnum won't start.

It started at first and ran like ****. It was surging something crazy at idle. Like 1000-1500 RPM. So I turned it off. Trying to start it again was worth a shot but, now it won't even start.

My codes are making me think my PCM is shot. But, I suspect my ABS harness too as well.

Here are the codes of relevance. The others are from my aftermarket stereo.

P0688-AUTO SHUTDOWN RELAY SENSE CIRCUIT LOW
P2100-ELECTRONIC THROTTLE CONTROL MOTOR CIRCUIT
P2101-ELECTRONIC THROTTLE CONTROL MOTOR PERFORMANCE
C1210–G SENSOR INPUT CIRCUIT PERFORMANCE
U0125–LOST COMMUNICATION WITH DYNAMICS SENSOR
P0112-INTAKE AIR TEMPERATURE SENSOR CIRCUIT LOW

Anyone have a guess as to the problem? I am still under warranty. Is this warranty labor? I really can't afford to pay to fix this right now.

Flashpaq Tuned PCM

Thanks,

If its warranty work, labor is included in that.

I would check the connection at the map sensor......everything up there runs through it........maybe the map sensor is bad.

P0688-AUTO SHUTDOWN RELAY SENSE CIRCUIT LOW is the only one i can think of that would keep it from starting. P2100 & P2101 might make it hard to start and idle erratically but shouldn't keep it from starting.

i'd be checking the ASD circuits, start by swapping the relay.

My dealer told me anything that would effect emissions is warantee, I believe until 100,000 miles. If your dealer is decent no worries. My car is heavily modded and never had an issue. Heck, I drove thru deep water and shorted out the O2 sensors, my dealer replaced them , NC. That was back at 100,000 miles.

check the battery, low voltage can cause the cars to run crappy and not start... try that first...

[Ultimatecarman45]

You have a 06' unless you have a lot of miles on it, this should be covered completely under warranty.

[Brilliant R/T]

Cris, call & go see Erik at Moore. He know are st!t.

[FactoryD]

Voltage is fine. I replaced the ASD relay and still no love.

The car starts but shuts down immediately.

Erik. Are you working today?

Weird series of codes...Seen P0688-AUTO SHUTDOWN RELAY SENSE CIRCUIT LOW
P2100-ELECTRONIC THROTTLE CONTROL MOTOR CIRCUIT
P2101-ELECTRONIC THROTTLE CONTROL MOTOR PERFORMANCE
On a Hemi truck...PCM connection issues and a few other weatherpack connections had(ETC) corrosion...

Might not be your issue being in AZ...But worth a peak...
Recently at my shop I have had a few DCX vehicles with software that has become corrupt...Good Luck!

[MadCharger]

Did you try returning it to stock with the Superchip?

I checked all the PCM connections and they looked fine. I guess I'll just have to get a flash to be on the safe side.

Yup. She's back to stock and I just managed to get her running too!

I was on the phone with fullofit_ and he narrowed me down to fuse 14 being bad. Now, the fuse itself is not bad. One side of connectors in the fuse box is gapped a bit too big. The fuse was very discolored on that side. So, I flipped it.

I'm not stupid enough to think that's my only problem. This will allow me to drive it to CHARGERSHEDs shop tomorrow though.

Thanks again everyone. This is why I love this place.

I'm glad you got it running again, Chris. That was the exact reason mine lost power to the ECM. I ended up leaving the GSM stake in there.

[firepower]

Damn man, sorry to hear the bad news.

Hope you're running good soon.

[FactoryD]

I was going to post this on your thread too John. It's weird though. I use fuse 10 (IIRC) for my fan mod and I don't remember ever using fuse 14. But, I have had the GSM mod for well over a year and my brain isn't what it once was.

Thanks again for your original thread.
