ECM fault code 168-1 indicates low battery voltage to the Engine Control Module, causing shutdown and electrical failures. This comprehensive guide covers diagnosis, repair steps, and prevention for diesel RV owners experiencing this critical issue.
Compare scan tools for Cummins 6.7 diesel engines in RVs. Covers professional and DIY options for diagnostics, codes, and DPF regeneration.
For your new Tiffin Allegro 33AA without a fixed ladder, consider mounting options like awning rail flag pole brackets, magnetic mounts for the metal body panels, or clamp-on solutions for the bike rack itself.
Guide to RV battery disconnect switches. Covers when to use, what loses power, and best practices for storage and daily use.
The ignition relay on a 1988 Ford E350 (Fleetwood Tioga base) is typically located in the engine bay fuse/relay box on the driver's side firewall, or in a separate relay box near the battery. Some models may have it mounted on the firewall or inner fender well.
A $6,400 DPF replacement quote is high but typical for dealers. Your 2022 Cummins B6.7 may still have emissions warranty coverage for 5 years/100k miles. Consider professional DPF cleaning ($800-1,500) or authorized Cummins dealers before replacement.
Super C popularity has grown due to commercial truck drivetrains (Freightliner, Ford), diesel reliability, and better towing capacity. Class A offers more interior space per dollar. Choose Super C for drivetrain and driving experience, Class A for living space and value.
Multiple coil codes on driver side likely common wiring, ground, or PCM driver issue. Check shared circuits before replacing coils.
Even with disconnect switches engaged, phantom loads and battery self-discharge can drain RV batteries during storage. Installing battery maintainers, using master disconnect switches, and addressing phantom loads will solve this issue.
Your Ford F53 460ci is stalling due to carbon buildup in the EGR valve disrupting idle air/fuel mixture. Clean the EGR valve and passages thoroughly, or consider an EGR delete with ECU tune for a permanent solution.
A Ford F53 V10 that cranks but won't start with cam sensor faults typically indicates wiring harness issues, timing chain problems, or PCM communication failures. Focus on checking the cam sensor wiring circuit and timing synchronization between crank and cam sensors.
Pedal Monster modifies throttle sensitivity, not actual power output. Results on F53 motorhomes are often subtle because the heavy vehicle limits acceleration regardless of throttle response. If you do not notice improvement, return it - it does not add horsepower.
V10 surging with air/fuel codes often has cheap fix - vacuum leak, intake gasket, or exhaust leak. Do smoke test or spray test before replacing more expensive parts.
Underhood generators and idling work but check local idle regulations. Extended idling wastes fuel and causes engine wear. Solar, generators, or DC-DC chargers are better long-term solutions.
Key issue is only 3.3V at fuel pump relay trigger instead of 12V. This prevents relay activation. Trace the wire feeding relay pin 86 to find voltage drop. Check for bad connections, corroded grounds, or damaged wiring between power source and relay.
