Results for "ECU failure"

Noticed my 2013 Newmar still rides incredibly rough through every crack and pothole even after replacing all six air bags. The ride height was never adjusted after the air bag replacement, and I'm worried I might be causing more damage or creating a safety hazard.

I upgraded from a Super C expecting a much smoother ride with the air suspension system, but this feels just as jarring. Am I missing something critical with the suspension setup? Could improper air pressure or ride height settings be causing this rough ride, and what other components should I be concerned about? I don't want to make things worse by continuing to drive it if there's a fundamental issue I'm overlooking. …more

Before every camping season rolls around, I face the same dreaded reality with my Ford V10 motorhome crawling up mountain passes like a wounded turtle. What are the realistic costs involved? Are there major risks to the engine I should know about? Is this actually worth doing or should I look at other options? …more

Tried everything my neighbor did to charge his LiFePO4 batteries but mine keeps frying the alternator while his works flawlessly — what's different? I want to install a temperature sensing device that can interrupt charging by opening the solenoid between chassis and house charging systems if the alternator gets too hot. I'm looking to spec out components and understand the installation process, and I'm open to hearing why this might not be a good approach. My goal is preventing alternator overheating when these lithium batteries draw high current compared to my old flooded or AGM batteries. I'm looking for technical feedback and am totally open to critique. …more

During my latest camping trip my Onan generator threw a fault code — got my multimeter ready and just need to figure out which diagnostic approach will crack this thing.

I'm seeing 12 or 13 blinks on my generator error display and want to understand what these codes might mean. Are these codes consistent across different Onan models? I'm hoping it's a minor issue and not something requiring a major repair.

Can anyone help me decode what these blinking fault codes typically indicate? …more

ECU died on my Ford V10 and the replacement part number 7C3A-12A650-DSC is discontinued from Ford. Salvage yards want $800 for a used one with no guarantee it'll work. Need to find a reliable source for this specific ECU or figure out what alternatives exist. …more

Somewhere between last week's torrential downpour and this morning, my 2014 Bounder Classic 36H with the 2013 Ford F53 V10 chassis developed what appears to be a cam sensor failure preventing startup. The engine cranks over strong but absolutely will not start. I've been chasing this for weeks and I'm really hoping someone can point me in the right direction.

Here's what I know: Forscan is showing cam sensor faults while cranking, even after I replaced the cam sensor. I've got fuel pressure, the crank sensor is new, and there are no stored codes. The tachometer moves during cranking attempts, so I know I'm getting some signal. After crank attempts, there's a strong fuel smell. I've disconnected the battery ground for over 5 minutes to reset any hanging codes.

I'm starting to suspect this might be a wiring harness issue or possibly something with the timing chain. I have a tone generator on the way to check for potential wire breaks. The frustrating part is that everything seems like it should work, but it's like the PCM isn't getting the right timing information.

I really need guidance on the most likely culprits for cam sensor faults on these V10s. What should I be focusing on to get this thing running again? …more

Planning to tackle this P0581 cruise control high voltage error on my 2007 F-53 chassis myself — got my tools ready, just need to know where to start. Already replaced brake switch, steering wheel switches, checked all fuses and wiring from dash to ECU. Horn works fine so clock spring seems okay.

Here's the key finding: disconnected the steering wheel connector completely to eliminate all external switches. Cleared the code and it stayed clear until I started the engine - then P0581 immediately returned.

Since the code sets with switches disconnected and all external wiring checks out, does this confirm an internal PCM problem? Looking for confirmation before spending money on ECU repair. …more

Called three different YouTube tutorials claiming to boost my 2000 Ford E450 V10's uphill towing power, but now my motorhome struggles even worse in the mountains. The unit struggles substantially on extended uphill grades, particularly during Rocky Mountain travel where sustained climbs can last 30+ minutes.

I'm evaluating several modification options to address this performance deficiency: rear differential gear ratio changes, SCT programming modules, K&N high-flow air filtration systems, and catalytic converter removal. I need to understand which modifications will provide measurable uphill towing improvements versus those that offer minimal gains.

What is the relative effectiveness of these power modifications for V10 mountain towing applications? I'm looking for a technical assessment of which upgrades deliver the most significant performance improvements for this specific application. …more
