How to verify and confirm the issue
Verifying electrical issues in your 2017 Dodge Charger requires a systematic approach. Don't jump to conclusions; many symptoms can have multiple causes.
- Battery and Charging System Test: Start by checking your battery's voltage with a multimeter (should be around 12.6V when off). Then, test the charging system; with the engine running, the alternator should produce 13.5V to 14.5V. A failing battery or alternator is a common culprit for widespread electrical chaos.
- Visual Inspection: Look for obvious signs of trouble. Check battery terminals for corrosion, inspect wiring harnesses for fraying, pinching, or burn marks, especially near moving parts or heat sources. Pay attention to ground straps connected to the engine block and chassis.
- Fuse Box Inspection: Systematically check all relevant fuses in both the under-hood Power Distribution Center (PDC) and the interior fuse box. A blown fuse indicates a circuit overload, but the underlying cause of the overload still needs to be found.
- Scan Tool Diagnostics: Connect an OBD-II scanner to check for Diagnostic Trouble Codes (DTCs). While not always a P-code (powertrain), electrical issues often trigger B-codes (body) or U-codes (network communication). These codes can point towards specific modules or communication errors. You can learn more about various OBD-II codes and what they mean.
- Component-Specific Testing: If a specific component is failing (e.g., a power window), test its switch, motor, and wiring using a multimeter to check for continuity and proper voltage supply.
- Technical Service Bulletins (TSBs): Research if there are any known TSBs issued by Dodge for electrical problems specific to the 2017 Charger model year. These often describe known issues and recommended fixes.
Common causes (most likely first)
Electrical issues in your 2017 Charger can stem from various sources, ranging from simple fixes to complex module failures.
- Weak or Failing Battery: An old or failing battery struggles to provide stable voltage, leading to erratic behavior in sensitive electronics.
- Failing Alternator: If the alternator isn't properly charging the battery, the vehicle's electrical system will run on battery power until it drains, causing failures.
- Corroded or Loose Ground Connections: Poor ground connections are a very common cause of intermittent electrical problems. They can lead to voltage drops and erratic component operation.
- Damaged Wiring Harnesses: Rodent damage, abrasion from vibration, or heat exposure can compromise wiring, leading to shorts or open circuits.
- Blown Fuses or Faulty Relays: While a blown fuse protects a circuit, it needs replacement. A faulty relay can prevent power from reaching a component.
- Faulty Switches: Individual switches (e.g., window switches, headlight switch) can fail internally.
- Body Control Module (BCM) or Other Module Issues: The BCM manages many body electrical functions. A fault within this or other control modules (like the radio unit itself) can cause widespread or localized issues.
- Aftermarket Accessory Interference: Improperly installed aftermarket stereos, lighting, or other accessories can introduce electrical noise, draw excessive power, or interfere with factory wiring.
Step-by-step diagnosis and fixes
Addressing electrical problems in your 2017 Dodge Charger often follows a logical progression:
- Check the Battery and Charging System: This is always the first step. Ensure the battery is fully charged and healthy, and the alternator is putting out proper voltage. Clean any corrosion from battery terminals.
- Inspect Fuses and Relays: Refer to your owner's manual for fuse box diagrams. Use a fuse puller and a test light or multimeter to check each fuse. Replace any blown fuses. Consider swapping relays for known good ones if you suspect a relay issue.
- Inspect Ground Connections: Locate common ground points in the engine bay and under the dashboard. Disconnect, clean, and re-secure any corroded or loose ground straps.
- Visual Wiring Inspection: Carefully trace wiring harnesses leading to the affected components. Look for any visible damage, especially where wires pass through grommets or near sharp edges.
- Test Specific Components: If a single component is malfunctioning, use a multimeter to test for power at the component and its switch. This helps isolate whether the issue is the component itself, the switch, or the wiring in between.
- Scan for Diagnostic Trouble Codes: Use an OBD-II scanner to retrieve any stored B-codes or U-codes. These can provide valuable clues about which module or circuit is experiencing issues. For more general repair guidance, you can browse all our repair guides.
- Isolate Aftermarket Accessories: If you have any aftermarket electrical accessories, temporarily disconnect them to see if the problem resolves. This can help rule out interference.

What is different on this year and model
The 2017 Dodge Charger, like most modern vehicles, relies heavily on a complex network of electronic control modules (ECMs) and a sophisticated wiring harness system. Unlike older vehicles where a single component failure might only affect that component, a fault in one module or a communication error on the CAN bus (Controller Area Network) can have cascading effects across multiple systems. While the 2017 Charger does not use the problematic Totally Integrated Power Module (TIPM) found in earlier Chrysler products, it still utilizes a Power Distribution Center (PDC) under the hood and a Body Control Module (BCM) that govern many electrical functions. These modules are highly integrated, making proper diagnosis with a professional-grade scan tool essential when basic checks don't reveal the cause.
