1. Symptoms of U0001 on Dodge Charger

When the Engine Control Module (ECM/PCM) on your Dodge Charger (5.7L / 6.4L 392 HEMI / 6.2L Hellcat (717HP–797HP) / Hurricane 3.0L Turbo) logs fault code U0001, drivers commonly observe:

Multiple warning lights illuminated simultaneously (Check Engine, ABS, Airbag, Traction) on Dodge Charger (5.7L / 6.4L 392 HEMI / 6.2L Hellcat (717HP–797HP) / Hurricane 3.0L Turbo)
Speedometer and tachometer gauges dropping to zero while driving on Dodge Charger (5.7L / 6.4L 392 HEMI / 6.2L Hellcat (717HP–797HP) / Hurricane 3.0L Turbo)
Transmission shifting into limp mode or engine failing to start on Dodge Charger (5.7L / 6.4L 392 HEMI / 6.2L Hellcat (717HP–797HP) / Hurricane 3.0L Turbo)
Scanner displays 'No Communication with Vehicle' on OBD-II port on Dodge Charger (5.7L / 6.4L 392 HEMI / 6.2L Hellcat (717HP–797HP) / Hurricane 3.0L Turbo)
Dodge Charger OBD-II Port Location
The 16-pin diagnostic connector is located Driver lower dash assembly next to hood lever. Plug in your scan tool to verify freeze-frame sensor values.

2. Most Likely Causes on Dodge Charger

3. Step-by-Step DIY Repair Guide for Dodge Charger

01
Measure CAN Bus Resistance at DLC Port

Turn ignition OFF, wait 5 minutes for bus to sleep. Measure resistance between Pin 6 (CAN-H) and Pin 14 (CAN-L) on the 16-pin OBD-II port. Normal is exactly 60 ohms (two 120-ohm terminating resistors in parallel). on the Dodge Charger equipped with 5.7L / 6.4L 392 HEMI / 6.2L Hellcat (717HP–797HP) / Hurricane 3.0L Turbo.

Required Tool: Digital Multimeter
02
Diagnose Resistance Results

If meter reads 120 ohms, one terminating resistor/module is disconnected. If meter reads 0 ohms, CAN-H and CAN-L are shorted together. If meter reads OL (infinite), bus is completely open. on the Dodge Charger equipped with 5.7L / 6.4L 392 HEMI / 6.2L Hellcat (717HP–797HP) / Hurricane 3.0L Turbo.

Required Tool: Multimeter
03
Measure Voltage to Ground on CAN-H and CAN-L

Turn key ON. CAN-H should measure ~2.7V; CAN-L should measure ~2.3V (summing to 5.0V). on the Dodge Charger equipped with 5.7L / 6.4L 392 HEMI / 6.2L Hellcat (717HP–797HP) / Hurricane 3.0L Turbo.

Required Tool: Digital Multimeter
04
Unplug Modules One by One to Isolate Defective Unit

If bus voltage is grounded or pegged, unplug modules (ABS, BCM, TCM, Radio) one at a time until bus resistance and voltage restore. on the Dodge Charger equipped with 5.7L / 6.4L 392 HEMI / 6.2L Hellcat (717HP–797HP) / Hurricane 3.0L Turbo.

Required Tool: Trim Tools, Socket Set
05
Repair Wiring / Replace Faulty Module & Clear Codes

Repair pinched twisted-pair wiring or replace the defective module causing network collision. on the Dodge Charger equipped with 5.7L / 6.4L 392 HEMI / 6.2L Hellcat (717HP–797HP) / Hurricane 3.0L Turbo.

Required Tool: Soldering Kit / Scan Tool

4. Dodge Charger U0001 FAQs

What causes code U0001 to trigger on a Dodge Charger?

On the Dodge Charger (5.7L / 6.4L 392 HEMI / 6.2L Hellcat (717HP–797HP) / Hurricane 3.0L Turbo), U0001 is most frequently caused by Short circuit to ground or short to power on CAN-High (Pin 6) or CAN-Low (Pin 14) or Terminating resistor open or missing in ECM or Cluster (60 ohms nominal across bus).

Where is the OBD-II port located on my Dodge Charger?

On the Dodge Charger, the 16-pin DLC diagnostic connector is located Driver lower dash assembly next to hood lever. Plug in any standard OBD-II scanner with the ignition in the ON position to read freeze-frame parameters.

Can I safely drive my Dodge Charger with code U0001?

No. High-Speed CAN bus failure disrupts communication between the Engine, Transmission, ABS, and Instrument Cluster. Given that U0001 carries a Critical severity rating, we advise avoiding heavy towing or aggressive throttle inputs until sensor readings are verified.
