2004 Dodge Hemi RAM Truck: Troubleshooting OBD-II Codes 004, 032, 2314, and 4800 with Wiring Issues
I own a 2004 Dodge Hemi RAM truck and am currently dealing with six diagnostic trouble codes (DTCs). I'm familiar with two of them: Code 443 indicates a Purge Control Valve error, and Code 480 points to a Cooling Fan 1 Control Circuit problem—both of which I can resolve. However, I’m struggling to interpret the remaining four codes: 004, 032, 2314, and 4800. These are not commonly documented in standard repair guides, so I’d appreciate any insight from experienced users. In addition to the codes, I’ve observed a persistent wiring issue: the cargo lamp remains on continuously. Removing fuse 18 turns off the light, suggesting a circuit fault. When I turn the dash switch to 'cargo,' the indicator on the gauge panel lights up. However, when the dimmer is set to its lowest position, both the rear cargo lamp and glove box light blink rapidly—indicating a possible short or signal interference. I have access to the original wiring diagram and am investigating whether these issues are related. While I suspect the problem may stem from wiring damage during a previous rebuild (the truck was rebuilt after an accident), I’m not certain of the root cause. This vehicle appears to have multiple underlying faults beyond what’s immediately visible. I’m not concerned about ownership—this is a non-owned vehicle—but I’d like to understand how these codes and symptoms might be connected, especially in the context of OBD-II diagnostics and electrical system integrity.
Have you verified the accuracy of those codes? Codes 004, 032, 2314, and 4800 are not commonly listed in standard OBD-II databases. What diagnostic tool did you use to retrieve them?
