2005-2010 Chrysler 300: "No Communications" with the ECM

Fri, 16 Jan 2026 23:02:43 -0700

My background: Former Chrysler technician, 17 year employee @ Alldata.com as Senior Technical Editor, ASE certified Master Tech (plus numerous other certs)

Vehicle: 1971 Plymouth Barracuda

Engine: 2006 Chrysler 300 6.1 Hemi with original engine harness, ECM, & FCM Transmission: Tremec 6 speed manual

200 PSI compression pressure while cranking.

The ECM has had the SKIM (security) option deleted by All Computer Resources, Inc.

I have triple-checked powers, grounds, 5 volt references, and wiring to both modules. Also has 12 volts & 2 grounds at the OBD connector.

The CAN high & low wires measure 60.8 ohms. Voltages on those lines measures 2.61 volts and 2.43 volts, respectively.

Crankshaft Position Sensor and Camshaft Position Sensor are making their respective outputs, as measured by an external oscilloscope.

The ASD Relay & Fuel Pump Relay do power up when the key is turned on, then the fuel pump relay waits for a cranking signal, then it re-energizes when the engine is cranking.

Has power to the coils & fuel injectors through the ASD relay.

Problems:

When I plug in the scan tool, it powers up but can't communicate with the ECM.
No spark output at the coils
No fuel injector pulses.

Any ideas for correcting the “No Communications” problem would be greatly appreciated.

According to Chrysler, the Front Control Module (FCM) acts as global communicator for all of the other modules. Does anyone know of a way to bench test the FCM?

Someone else suggested trying another ECM, in case this one is bad. Sure, it could be bad. I'm not sure if it was working before the SKIM delete was performed or maybe it went bad BECAUSE that was performed. I thought about plugging this ECM into another car, just to see if it would communicate, but according to Chrysler, doing that would reactivate the SKIM system, thus negating the $125 SKIM delete that I've already paid for.

Chrysler 300: 2006 Chrysler 300 Limited Parasitic Battery Drain?

Sun, 14 Dec 2025 15:37:51 -0700

With ignition off the car drains nearly 2 amps. I have tested all fuses and relays, front and rear electrical boxes, with only minor change, except for fuse #1 (Ignition Off Draw) in the rear box. By pulling that fuse the drain is stopped but the security system, power locks including trunk latch, radio/entertainment system, dash compass, and perhaps more, are disabled. Other than these, all systems seem to work with fuse #1 disconnected. Has anyone had any experience with this type of electrical issue? Thanks
